YECs on Fossils and the “Evolutionary Timeline”

Because Young-Earth Creationists are so defensive of their model that requires the earth to be between 6,000 to 10,000 years old, they are always out to discredit the scientific date of the earth with anything they can fish out. They feel that if their interpretation of the Bible is wrong -to hell with other legitimate interpretations,- then their whole world will fall apart. This leads many YECs to make many bogus arguments for a young earth like  the decay of the magnetic field, the recession of the moon, etc, etc., etc., yada, yada, yada…. Then, another favorite tactic they use is to point out a fossil find and claim it is “out-of-place,” and that therefore the timeline is all wrong, and therefore their model of a 6,000 year old universe has to be right. I see this particular argument used more by Brian Thomas who is employed by the Insitute for Creation Research than anywhere else.

One of my favorite examples of  Thomas’s use of the “fossil out-of-place” argument is  from an article entitled “Fossil Footprints Trample Evolutions Timeline.” — It talks about arthropod trace-fossil foot prints which were found in Pre-Cambrian strata in Nevada. Thomas presented this find as if it were a blow to the Evolutionary theory because it would require some reevaluation of determining when arthropods appeared. It never occurred to them that this find actually hurts Creationism more than it could ever hurt the present theory of Evolution. More precisely, this discovery hurts the favorite Creationist argument about the so-called Cambrian”explosion” because it shows that complex, animal life was around 30 million years before.

There are several other examples that the Institute cites, and I’ll address some of them here just to show how they 1) show ignorance of the person making the claim, and 2) how are completely irrelevant to the topic of the “evolutionary timeline.” Further reading of ICR claims on the subject will show any informed person how the Institute takes certain scientific discoveries and takes them out of context to try to refute Evolutionary theory.

  1. One claim that the Thomas makes is that a  newly discovered amber trapped spider web too old for the timeline. A news article he cites of this fossil find, in fact, shows that spider webs had evolved long before it was first thought, however when one does more research on spider evolution, the apparent “harm” done to the timeline really doesn’t exist. This fossilized web’s age is estimated at 140 million years, while  the evolution of spiders is thought to have started some 400 million years ago. That gives the web about 260 million years to evolve, so there is no harm done here.
  2. Another claim that he made is that the T-Rex body structure evolved 60 million years “too early.” This claim is based on a newly discovered relative of the tyrannosaurs now called Raptorex. I seriously cannot help but see the irrelevance of this fossil to debunking the so-called “timeline.” It never crosses Thomas’ mind that rather than hurting the current theory of evolution, this helps it by aiding the construction of a phylogeny of the tyrannosaurs.
  3. Claims of human artifacts, such as evidence of boats and jewelry, are used to say that we have always been the same species. We now know that Homo neandertalensis had fassion sense, but nobody disputes this, so it is irrelevant. Also, multiple mtDNA tests show they are not the same species as Homo sapiens, despite the YEC model’s insistence. And the evidence that Homo erectus was a mariner is really not news since we knew that for over a decade (at least since 1998). Hence, this is also irrelevant.
  4. Another apparent contradiction of the timeline is the discovery of fossil ambers dating to the Carboniferous which lasted from 355 to 300 million years ago, though the first flowering plants known to the fossil record appear during the Cretaceous (125 million years ago). The Brian Thomas criticizes the scientist who discovered them of  evolutionary bias because he said this doesn’t necessarily mean that flowering plants appeared so early, but that it shows that aspects of them were starting to make an appearance. But at the same time, he doesn’t provide any credible evidence to the contrary, so they affectively fail to show how the timeline was falsified.

The only thing some of the examples above show is a slight reevaluation of  some of the current scientific understandings., but that’s all. On the other hand, some of the examples don’t affect out understandings at all. This kind of makes me wonder if the employees at ICR sees any unexpected scientific find as an inherent refutation of Evolutionary theory as we know it.

As I see it, ICR has a very odd definition of an “out-of-place” fossil. In one post entitled Cambrian Fossils Found in the Wrong Place,” it is argued that since soft-bodied creatures were thought to be stem ancestors to the Cambrian fauna were found in some of the same layers, one could not have evolved into the other because  the argument for evolution  “relies on the absence of these creatures in higher layers to support the assumption that they ‘diverged’ into ‘later’ life forms.” –This reminds me of the argument “If humans evolved from apes, why are there still apes.”  Even if  a certain animal evolved into another species, there is no reason to assume that evolutionary ecenario “relies” on the absence of the mother species.

So really, not a single one of the examples given of “out-of-place” fossils given by the Institute refute any of  the important aspects of Evolution, and any revision that is made from them, so far, is only minor. Any fossil that actually refutes our scientific understanding should be unexplainable, like fossil rabbits in the Cambrian, and so far, the Young-Earthers have failed.

The Truth on the Cambrian “Explosion”

The fifty-three million year period known as the Cambrian is important to the fields of geology and biology because that was when many major groups of kinds of creatures with hard parts and shells, appear in the fossil record. This has been called the “age of trilobites” which were marine arthropods. — During this period of time, there was a unique episode in the history of  life, an apparent evolutionary radiation in which life seems to “explode” in the fossil record. Complex marine animals with hard, preservable parts appear over a rapid span of time in the geological record. This event has been called the Cambrian “explosion.”

At the time Charles Darwin published Origin of Species in 1859, the fossils in the Cambrian were the oldest known ancient life, and paleontology and research in the fossil record hadn’t advanced as much as it has recently. — Darwin himself commented on it saying,

To the question why we do not find rich fossiliferous deposits belonging to these assumed earliest periods prior to the Cambrian system, I can give no satisfactory answer. . . . Nevertheless, the difficulty of assigning any good reason for the absence of vast piles of strata rich in fossils beneath the Cambrian system is very great, and may be truly urged as a valid argument against the views here entertained.

Darwin’s statement, that the lack of fossils before the Cambrian, could be used as “a valid argument” against his theory has struck a chord with critics of Evolutionary theory into the present. In fact, it is hard to find many Intelligent Design and Creationist publications that do not talk about the apparent lack of fossil life before the Cambrian, using it as a “refutation” of Darwinian Evolution — “Darwinism,” as they call it.  The apparent radiation of life that occurred called the Cambrian “explosion” is what they appeal to saying that this was the fauna in this strata appeared “all of a sudden, with no evolutionary ancestors.”

If it could be shown that animal species, in fact, appeared without any kinds of evolutionary ancestors, then Evolutionary Theory would be in trouble. That is a fact. However, if the scientific literature were to show that these fauna had viable ancestors, then there is no problem for the scientific consensus.

First of all, it should be pointed out that the Cambrian “explosion” was only explosive in geologic terms. It is usually estimated to have lasted between 10 to 25 million years —- which is a far cry from the impression that Intelligent Design proponents attempt to give when they say that phyla appear “all of a sudden.” Though rapid in geologic terms, it is hardly rapid on the time scale, and it is not far-fetched to allow plenty of evolution within that time period. It would appear that Antievolutionists are confused by the usage of the word “explosion.”

The claim that phyla appeared “all of a sudden with no viable ancestors” would also be damaging . . . if it were true. But it is not. There is sufficient evidence for animal life before the Cambrian explosion:

  • Complete fossil embryos pre-dating the Cambrian “explosion” by 10 million years were discovered in 2006, and show that animal complexity was already starting to bloom. Fossil embryos are a rare enough find without them being complete.
  • There are plausible pre-Cambrian ancestors for trilobites. For example, there are the Spriggina floundersi, the so-called “Soft-bodied trilobite,” as well as Parvancorina. — Parvancorina is classified, interestingly enough in the Kingdom Animalia, and was possibly even an arthropod. — Also, to make matters worse, there are many transitions between trilobites which are extremely diverse and themselves indicate plenty of Evolution, not just during the 300 million years of their existence, but also during the Cambrian period.
  • Even if non of the examples listed in the last example above were not arthropods or ancestral to trilobites, there is still proof that arthropods did in fact exist before the Cambrian period. Arthropod trace fossils have been found in Nevada in strata dating to 30 million years before the Cambrian, proving that there were animals with legs much earlier than once thought. — Amusingly, some Creationists have attempted to use this one example to refute the Evolution timeline not realizing that this find did more harm to the Creationist argument of the Cambrian “explosion.”
  • There is new fossil evidence of bilateral animals which was recovered from the Doushantuo Formation in China dating from between 40 and 55 million years before the Cambrian. The specimen, called Vernanimalcula, had features like a mouth, a gut, an anus as well as surface pits. This would itself show the Cambrian was not the starting point for complex life.
  • Newly discovered “chemical fossils” have demonstrated evidence that Sponges, as the first Animal life, had already existed around 635 million years ago, or between 90 to 100 million years before the Cambrian “explosion.”
  • The Cambrian “explosion” just doesn’t stand up to the genetic evidence. Molecular clocks indicate a more ancient starting point from between 800 million to 1.2 billion years. This indicates that the fossil record has plenty of gaps, though genetics seems to compensate for what is lacking to a certain extent.

Another detail to consider is that it is plausible that, even though speciation seemingly did pick up during the radiation, it is may in fact not be anything special when compared to other similar radiations that occurred. — Using trilobites as a statistical basis, Bruce S. Lieberman concluded that “speciation rates among olenellid trilobites in the Cambrian radiation were not unusually high.”  He then also said that if these results can be extended to other groups, then special rules aren’t necessary to explain the Cambrian “explosion.”  — This, in my opinion, falsifies the Creationist impression of  rapid and sudden appearance.

Since it is widely agreed by biologists that the Cambrian “explosion” was a real event, there remains the problem of  attempting to explain what caused it, and these explanations are controversial in the scientific community. Plenty of them have to do with environmental changes such as “Snowball Earth”, and also some have proposed that an increase in levels in oxygen in the atmosphere allowing big-bodied animals to thrive. This second proposal could fail assuming that the big-bodied Ediacaran fauna (existing 30 million years before the Cambrian) are in fact animals. One model indicates it -as well as other radiations- may have “changes in the pattern of gene regulation.” On the other hand, indications show that Hox and other developmental control genes were already in existence before the radiation, though genomic repattering during the early Cambrian which involved some key genes and regulators.

But then again, there are scientists that are starting to question whether or not it was even a real event based pre-Cambrian fossil evidence as well as genetics, a lot of which is given above. Naturally, if this is the case, then there is no need to explain it, much less resort to the supernatural.

Any objective look at the Scientific evidence shows that the so-called Cambrian “explosion” cannot be used as evidence for a “creation event” because of its suddenness.  As a matter of fact, some of the fossil finds would seem to muffle the “explosiveness”  since it is now clear that complex life existed at least around 40 to 55 million years before. The implications of this is that there are possible evolutionary ancestors to the Cambrian multicellular life.  — Antievolutionists should update their claims if they want to retain any credibility.

The “Global” Deluge – Is it Unbiblical?

To explain the geologic record, Creationists read the Biblical story of Noah and the flood into the evidence. They look at the fossil record and reason that these are creatures that just didn’t make it in the Ark and perished when the flood waters overtook them. The story of Noah is one of the most famous stories in the Bible, and gives a lesson about renewal of the old. But Young-Earth Creationists propose that Noah is more than myth: He is real, historical person, and that his flood covered the entire planet.

I will not argue against the existence of  Noah as a historical person. Personally, I have no reason to believe that he didn’t exist, being a Christian. But what I will argue against is that the flood covered the entire planet since I believe the evidence in the geologic record points against it. — And I have yet more reasons than just geology to suspect the flood was a “local” event, and not universal which I will focus on in this post.

The reason why YECs insist on a global flood is because their model demands it. It is supposed to account for the fossil record, and it is based on their interpretation of the story found in the book of Genesis. There are also some “hard” atheists that use the same arguments against the idea that Genesis allows for a local flood in an attempt to say that acceptance of an old earth or Evolution is incompatible with Christianity. My personal assessment of the claims made by both groups is that they are wrong and misguided. In fact, I think the reading of  a “local” flood in Genesis is not only plausible, but also Biblical.

The basic Biblical support that Creationists have for a global flood is the universal language which is used in the Genesis account:

  • I am going to bring floodwaters on the earth to destroy all life under the heavens, every creature that has the breath of life in it. Everything on earth will perish. (Genesis 6: 17)
  • Seven days from now I will send rain on the earth for forty days and forty nights, and I will wipe from the face of the earth every living creature I have made. (Genesis 7: 4)

The language from these verses is most definitely universal, so it is no wonder that modern readers, Creationists and “hard” atheists alike, understand the “global” deluge as the only viable interpretation of the flood account. — Notice my stress on the term “modern readers.” — Though somewhat convincing at first glance, universal language is hardly an indicator that the Biblical account was intended to teach that the planet as a whole was covered in water. Such usages of the term  “All under heaven” have been used to describe geographically limited areas. For example, during the time of the Roman Empire, the Romans claimed to rule the “whole earth.”  Also, In ancient China, the domain of the emperor was said to be “all under heaven,” but obviously this only applied to China and neighboring states, and not to nations far out its reach.

In fact, the Bible itself uses this universal term in geographically limited contexts as well. For example, Acts 2: 5 says, “Now there were staying in Jerusalem God-fearing Jews from every nation under heaven.” — Obviously, “all under heaven” does not mean the entire planet. It most certainly does not include other regions like North America, Japan, as well as China and Korea. These terms were simply a way of expressing one’s self in ancient times, and they didn’t have the same meaning as they do today.

Another detail to take into account is the Hebrew word for “Earth” which is אֶרֶץ (pronounced as “eretz”) which is used in the flood story. — Though this word can be understood and the entire planet, it also has several other meanings like ground, soil, land, country, territory, district, and region. Most of these can actually be substituted for “Earth,” showing that the flood can be understood as covering a local region or territory.

A couple of Atheist and Creationist rebuttals to the “local” flood that I read object on the basis that the flood story says that the mountains were covered,

The waters rose and increased greatly on the earth, and the ark floated on the surface of the water. They rose greatly on the earth, and all the high mountains under the entire heavens were covered. The waters rose and covered the mountains to a depth of more than twenty feet. (Genesis 7: 18: 20 )

Certainly this could falsify the local flood, right? — Wrong! Objections made of the basis that the waters covered the “mountains” are only dependent on English literalism which is not a legitimate reading of the Bible if the word in the original language can be understood differently. — The Hebrew word for “mountains” is הַר (pronounced as “Har”) which also means hill or even hill country. So the passage can simply be understood as saying that the flood waters elevated over the hills by over twenty feet.

Granted, this information doesn’t prove that  global flood isn’t what the writers of Genesis intended to write about. It only shows that a local flood is a legitimate understanding from the Biblical text. — If we left it all here, we would think that both interpretations, though different from each other, are harmonious with the Bible itself, but I have no intention of leaving it to that. It is my contention that the global flood is unbiblical, not just simply irrational. — Now, is there any Biblical evidence to back me up? You bet there is! — One of the best pieces of evidence comes from the prelude to the flood story itself,

The Nephilim were on the earth in those days—and also afterwardwhen the sons of God went to the daughters of men and had children by them. They were the heroes of old, men of renown. (Genesis 6: 4)

The Nephilim were a race of pre-flood people. Some commentators blame them for the evil in the world which caused God to bring the flood. But notice that the story says they were “on the earth in those days — and also afterward.” This implies that not only wasn’t the flood sent to destroy this race of people, they survived the flood.  They are mentioned to still be living in the time of Moses (Numbers 13: 33 ). This could only logically be true if the flood was a local event, and not global. — The one objection I ran across for this point is that the Nephilim that were around before the flood were probably not the same as those that existed afterwards. However, even if I grant that Numbers 13:33 is talking about an unrelated race, that doesn’t explain why Genesis 6:4 implies that  pre-flood and post-flood Nephilim shared a common progeny as they are both associated with “the sons of God who went to the daughters of man”  implying that they managed to survive the flood.

Then there is also the drainage of the flood. Genesis 8: 1 says that a wind was used to cause the waters to recede which would have been pointless if the flood were global because the water that got blown away would simply have been replaced my different water that wasn’t there previously. — Also, Noah is said to have sent a dove which returned with an olive leaf (Genesis 8: 11). This is also evidence against a global flood because the time allowed in the Bible for the recession of the waters would not allow an olive tree to have grown by then. Also, the salt water of the flood would have destroyed much of the plant lifeeven the olive trees, not to mention the terrestrial conditions on the earth wouldn’t have been suitable for plant growth for a while.

Interestingly enough, even the writings of Flavius Josephus, the first century Jewish historian, seem to give credence to a local flood when one reads between the lines. After his retelling of the flood, he mentions other historians which mention similar events, and then quotes Nicolaus of Damascus,

Nicolaus of Damascus, in his ninety-sixth book, hath a particular relation about them; where he speaks thus: There is a great mountain in Armenia, over Minyas, called Baris, upon which it is reported that many who fled at the time of the Deluge were saved; and that one who was carried in an ark came on shore upon the top of it; and that the remains of the timber were a great while preserved. This might be the man about whom Moses the legislator of the Jews wrote.” (Antiquities of the Jews 1: 94-94)

This is significant for two reasons: 1) Because Josephus believes that Nicolaus is describing the flood of Noah, and 2) he mentions that there were many that fled and were saved from the deluge, and he seemingly differentiates them from the passengers on the ark. This implies that these other non-Noachian survivors had different means of escape besides the Ark of Noah.  This would only make sence in the light of a local flood, not a global one. — Also, it is notable that Josephus does not correct Nicolaus as to others escaping the flood besides the passengers on the ark, implying that he agrees with him. It would be out of character for Josephus to not correct him if he disagreed with him.

The idea of a local, non-global, flood has plenty of support. The original Hebrew shows that this particular understanding id viable, and the Bible itself confirms it by implying that other people (i.e., the Nephilim) survived it. That latter detail should surely be a stumbling block to anyone who believes in a global flood. However, it is not problematic if one embraces the local flood. — In fact, for these reasons, I consider the local flood the only viable understanding of the Genesis story, and that the “global” flood is not only irrational but also unbiblical.

Devoluton and an Evolutionary “Ladder”

When I first began reading Creationist arguments, I ran across the claim that humans as well as all other species were deteriorating. — One well known Creation Scientist I read claimed that the first humans lived for several hundreds of years and were therefore superior to all humans alive today. And based on that reasoning, he claimed that we were “devolving,” not evolving — devolving since the time of Noah’s flood. My reading of Creationist and Intelligent Design lit is that for evolution to be true, everything has to lead to an improvement.

Joseph Mastropaolo, a Creation “scientist,” for example, talks about medical disabilities and harmful mutations saying that this argues against evolutionary theory. He says that if evolution were true, then there should be less mutations less disease.

From the medical literature, the evidence suggesting evolution is zero and the evidence suggesting the exact opposite, devolution, is more than 15,400. Obviously, evolution is the exact opposite of reality.

Just as a side note, Mastropaolo’s insistence that evolutionary theory makes the prediction that there should be less disease fails to take into account that the viruses and bacteria that are responsible for sickness and disabilities evolve as well, so the persistance of disease is perfectly consistent with evolution. — Also, he says,

If evolution is true, then we should observe a decrease in human mutations, medically designated human genetic disorders, over time according to one definition of evolution, change over time, and another definition, natural selection. [ . . . ] The actual data show that genetic disorders doubled every 13 years through the sixties, seventies and eighties. In the nineties, genetic disorders doubled in about half the time, every seven years.

How ’bout that? I guess for evolution to be true, harmful mutations and genetic defects should become less frequent as time goes on. This is quite an over-simplistic understanding of how evolution works. — I think I’m being too generous by even describing his description of the process as an “understanding” because that’s not how evolution works at all. It doesn’t ensure against more disabilities in the future, and it certainly never claimed to guarantee that the occurence of detrimental mutations would be reduced in the future.

Such claims and insinuations are common in Creationists literature. Their perception is that there is a certain requirement that there there is a dictated direction from the simple to the complex, and that anything that seemingly goes in the opposite “direction” is a refutation of evolutionary theory. — The idea of “devolution” is based on the common misconception that evolution is directionary, that is, that increasing complexity is a necessary outcome for evolutionary change. The truth is that evolution doesn’t dictate any such trend. It has no pre-ordained direction.

The idea of a “ladder” of progression was proposed by several, but notably by the French naturalist Jean Baptist de Lamarck who believed that the simplest life forms were on the bottom while the most complex forms (i.e., humans) were on the top. Charles Darwin, however, did not subscribe to Lamark’s ideas, considering them unreliable. In fact, by the time Darwin had appeared on the scene, the idea of a chain was losing it’s support, but Darwin was the one that ultimately demolished it. — He envisioned a tree with the branches dividing, and so on, though modern evolutionary theory is shown as more of a “bush.”

Rather than just adding, evolution often reduces as well. Tapeworms lose their guts, cavefish lose their eyes, and humans lose their appendix. The ancestors of these particular species had fully functioning versions of these particular organs, though the modern counterparts are either semi-functional or non functional. There is no reason why apparently “simple” creatures cannot have evolved from more complex ancestors, and there is reason why this would happen: If you don’t use it, you tend to lose it.

The claim that devolution occurs rather than evolution shows that Creationists either do not understand evolution, or they feel the need to redefine it so they can make it look like a pseudo-scientific absurdity. The reality is that ‘devolution’ is not a legitimate biological term. So far, I haven’t been able to find it in any science textbook. The only people who use the term tend to be just laypeople or Creationists.

As a final observation, talk about “devolution” and an evolutionary “ladder” actually causes a fundamental contradiction of another common Creationist fallacy: The claim that Darwinian Evolution is based on pure chance. If evolutionary theory dictates that organisms absolutely have to become more complex, then how could evolution be based on pure coincidence? Logically, you cannot accept both ideas. Though to be honest, Evolution isn’t based on pure chance: Though mutations are random occurences, Natural Selection is the exact opposite of chance.

The fact of the matter is, the concept of an “Evolutionary ladder” is an oxymoron. It has no place in modern biology, so if you hear anyone  using such a term, you can be sure that person doesn’t understand evolutionary theory.

Evolution, Theory and Falsifiability

A while ago, I was reading a book entitled The Reluctant Mr. Darwin which gives details about the time that Darwin was developing his theory of Evolution. I was developing an interest in Darwin the man rather than just his theory of natural selection which was why I got the book in the first place. What happened was, a member of a certain church saw the book, and we got into a short discussion. After our really short discussion about Darwin and Evolution, he said to me “It’s a theory,” putting plenty of stress on “theory.” A lot of Creationists love to use the “Evolution is a theory” argument, apparently, because that semantics technicality gives them a justification to reject it all together.

The argument that evolution is just a theory is made on ignorance of the scientific method, or methodological naturalism. This is made up of several steps such as 1) observation, 2) hypothesis, 3) testing, 4) revision, and 5) theory. — Notice that hypothesis and theory are two separate steps in the scientific method. They layperson uses the two terms interchangeably. Not so in the scientific community.

Some of the mentioned steps of the scientific method are self-explanatory, but it works like this: A hypothesis is used to explain a certain observation in nature. The hypothesis is used to make a prediction, that is, if the hypothesis predicts that X should happen, and it does, then it has support. However, you need to keep testing the hypothesis against other predictions that it makes, and if it does not pass them, then it needs to be revised. On the other hand, if it passes every test given, then it becomes a theory. — To a scientist, a theory is well supported by the evidence. It is not just a hair-brained idea that was just dreamed up. Indeed, scientific “theories” are described “proven hypothesis” and are more like scientific laws.

From this, to say that evolution is “just a theory,” Creationists are unwittingly saying Evolution is well substantiated and tested. Evolution, therefore, is only a “proven hypothesis,” it is only as useful as a scientific law. When Creationists argue along these lines, they are crossing definitions of the same term which is really not a valid line of argument. Indeed, pulling out the “it’s only a theory” card is nothing more than semantics.

Casey Luskin, who is a well-know Intelligent Design proponent at the Discovery Institute in an essay he wrote on the subject recommends against resorting to calling evolution a theory because it can imply to Evolutionists that the Creationist/ID proponent cannot cite evidence against it. — He then points out,

The “evolution is just a theory” line can come off as if the speaker really thinks “evolution is just a guess, so I don’t have to believe it if I don’t want to.” In fact, neo-Darwinian evolution as a whole is not merely a guess and most Darwinian scientists will provide reasons why they think it is the best explanation for the diversification of life.

I agree very little with Casey Luskin, but he cannot be more right in this case. When this argument is used, the implication is since evolution is a theory, there is an excuse to simply dismiss it purely our of convenience. — “It’s convenient for me, therefore I will reject it. It’s a theory, not a fact.” — Under this logic, we could dismiss other scientific theories such as germ theory, plate tectonics, the big bang, general relativity, and also gravitation. All of these are theories, and yet they have been verified by the data against observations that very well could have falsified them. — And that’s part of science right there. In order to become a theory, the proposal has to make prediction that can be falsified if it’s wrong. If later observations go against the proposal, then it has been falsified. If not, it has been verified, and it moves into becoming a scientific theory.

One of the most obvious predictions that Evolution makes is that ancient life forms in the fossil record have to show some change and transformation from certain species to others. So intermediate features between ancient fossilized creatures and modern living animals have to be discovered to verify this particular prediction. — And it so happens that fossils that seem to fit this description, in fact, exist. There are intermediate fossils between land mammals and whales, transitions between fish and tetrapods, as well as intermediate forms between ape-like creatures and modern humans.

Another prediction that is made is genetic similarity between species. And no, I don’t mean the 95 to 98% DNA similarity between humans and chimps, though there is that to. I’m talking about shared plagiarized molecular mistakes shared between different species. — Shared plagiarized errors in genetics imply a common source (or ancestor) for differing species, much like shared copying mistakes between different publications indicate that the more recent writer copied from the other.

Considering that Evolution has been tested by these predictions, and even others, common descent is just as much a legitimate part of science as any other scientific theory. And this is despite the claim made by some creationists that evolution doesn’t even meet the standard of a respectable hypothesis. In fact, there is a lot more evidence for evolution than what I have mentioned here. — The fact that there were discoveries that could have been able to falsify evolution, and that it has been verified, shows that it is more than just a hypothesis.

The Birth of an Evolutionist

Having been raised in the Seventh-Day Adventist Church, I grew up hearing the theory of Darwinian Evolution often scorned as an atheistic  rationality against God. I was raised to believe that the earth was no more than 6,000 years old and that therefore “we didn’t come monkeys.” In fact, the SDA church is the source for the modern YEC movement. Young Earth Creationism was a requirement for me when I was baptized into the church and officially became a member.

As I went to private schools run by the church, we were often indoctrinated into Creationism. I remember in my sixth grade science book, the flood of Noah was used as an explanation for geological formation, and that humans and dinosaurs co-existed, and that humans were individually created separately from apes. — Ironically, the same textbooks classified humans as primates along with monkeys and apes. — However, despite all the Creationist indoctrination i was put through,  little by little, I began losing faith in a Young Earth.

I began using common sence to determine that the earth and universe was much older than 6,000. It was basically all because of starlight and light speed. I reasoned that if light took millions of years to reach us here on earth, then the universe had to be older. — However, I still didn’t consider Carbon-14 and other dating methods because I was taught all my life that they were inaccurate. I then revised the belief in the creation week into long ages much like progressive creationists though I had no idea progressive creationists existed. I then also concluded that the flood of Noah was a local event because it was the only explanation that seemed to make sense. Certainly this would be acceptable, wouldn’t it?

A recently as the summer of 2008, I had stayed away from evolution thinking that there was no reason to accept it, or rather “to believe” in it. Finally, in all my ignorance of evolutionary theory, I left a comment on a blog that talked about Evolution being “both theory and fact.” — I ignorantly commented that Evolution was only a hypothesis, and nothing more, but that I accepted an old earth. This then drew other comments calling me ignorant . . . and I was.  I had no real response.

I then decided to look up what scientists said about Evolution. I was then troubled by all the support that it enjoyed in the scientific community. The fossil and genetic evidence I ran across bothered me, and the YEC apologetics I found online didn’t give me any comfort. The most convincing Creationist I read online was Harun Yahya, but I think that was only because he was not a YEC. He accepts the old age of the earth. As a result, I took more comfort in his works than I did from organizations like Answers in Genesis and the Insitute for Creation Research, though this isn’t to say I never read up on them.

In short, I did everything possible to avoid accepting that Evolution could possibly be true for the next full year. After all, I thought that if Evolution were true, then that would inherently mean that God was not our creator. I began reading Micheal Behe’s Darwin’s Black Box and Harun Yahya’s The Evolution Deceit, and used the arguments in those books against Evolution. I then was countered by even better arguments against those given in those particular books.

By July of 2009, I was finally losing what little faith in Creationism I still had. Though in the early part of that month, I was still an Old-Earth Creationist, my comments about Evolution became less and less dogmatic. I finally made statements like “I am a Creationist, but Evolution may in fact be true.” — What finally got rid of any doubt of harmonizing God and Evolution was a short three video series I randomly found on YouTube which beautifully ( and it can be watched by clicking here.) For at least a couple of days after this, I considered the points made, and I finally decided to do more investigation about the topic. By investigation, I mean unbiased with no preconceptions. This research fully convinced me that Evolution was indeed a scientific fact, and that God was fully in harmony with Science.
