Debate:Is the theory of macroevolution true?

Post Your Thoughts

Yes

Arguments for * All life on Earth shares common ancestor

• All life on Earth shares common ancestor

1. All life on Earth shares molecular features.
   1. Same macromolecules (DNA, RNA, protein)
   2. Same monomers for those macromolecules (five nucleotides, twenty standard amino acids)
   3. Same chirality of molecules. DNA in all complex life forms is right-handed, research suggests[1] that left-handed DNA would work just as well.
      1. If life forms did not have common ancestors we would expect to see a fairly even distribution of left and right handed DNA.
   4. Genetic system:
      • Ribosome structure
      • tRNA structure
      • The universal genetic code (and slight deviations from it)
      • Information encoded in nucleotide polymers (DNA or RNA).
2. Differences between organisms can be explained by known mechanisms of genetic mutation.
   • Counter: There has not been enough time for mutation to generate existing biological diversity.
     • Counter: There has been enough time enough time to generate existing biological diversity.
     1. The speed of evolution is measured by the darwin (change in an organism's character by a factor of e per million years.) [2]
     2. Evolution in the lab can be as high as 200,000 darwins.
     3. As measured by the fossil record, the average evolutionary rate in the wild is 370 darwins.
     4. A rate of 400 darwins is capable of turning a mouse into an elephant in just 10,000 years.
   • No other (non-human) process has been observed to generate biological diversity.
   • Extensive biological diversity existed before humans had the ability to create new forms by molecular recombination.

>95% of academic biologists support it.

Those who argue against it have a poor understanding of biology.

Comment on logic: I am sorry, but your answer is an appeal to authority, a common logical mistake. But its ok. I am sure there is still more evidence to support your point? David R

Reply: You say that "95% of academic biologists support it." What evidence do you have to support this statement? I have often wondered if there was a place were one could view this sort of information. It would be most helpful.

You go on to say that "Those who argue against it have a poor understanding of biology." Again, what evidence do you have to support this statement? Here are some creation biologists, to name a few:

• Dr. Raymond G. Bohlin, Biologist
• Dr. Andrew Bosanquet, Biology, Microbiology
• Prof. Chung-Il Cho, Biology Education
• Dr. Chris Darnbrough, Biochemist
• Dr. David A. DeWitt, Biology, Biochemistry, Neuroscience
• Dr. Dudley Eirich, Molecular Biologist
• Prof. Carl B. Fliermans, Professor of Biology
• Prof. Robert H. Franks, Associate Professor of Biology
• Dr. Duane Gish, Biochemist
• Dr. D.B. Gower, Biochemistry
• Dr. Bob Hosken, Biochemistry

All of them have doctoral degrees in some sort of biology and all argue against macro-evolution and for creationism. Are you claiming that all of them have a poor understanding of biology? PhilipB 23:29, 17 December 2006 (EST)

Another Reply: I assume that you have a better understanding of biology upon which to base this attack? Please enlighten us; how would a wise biologist refute the facts that seemingly disprove evolution? Where is the host of intermediate links? When have biologists observed an organism acctually gain genetic information through a mutation rather than lose it? BenjaminS

Having studied and worked with scientists for a decade, and spending another decade debating armchair evolutionists, I've found that it is usually someone unsuccessful in the hard sciences (physical, chemistry, biology and you might add mathematics) who is drawn most to evolution. The late evolution-promoter Stephen Jay Gould, for example, was merely a geology major at Antioch College. Big evolution promoter Richard Dawkins was an assistant professor at Berkeley, and then a lecturer, and then it's not clear to me what his academic status was for a while. Meanwhile, real experts, such as Richard Sternberg who has TWO PhDs in evolution fields, have been critical of the theory. But Sternberg was harshly disciplined for daring to question the theory, and few are anxious to risk similar retaliation.

>It is at least a puzzle to understand how Creationism accounts for seemingly-badly-designed aspects of anatomy and physiology. For example, the eyes of cephalopods (squid, octopus) and those of vertebrates (mammals, including humans) are strikingly similar in their general "design" with one conspicuous exception. In the cephalopod eye, the retina is structured exactly as one would expect: the light-sensitive receptors face forward, toward the lens, and the nerve fibers that join to form the optic nerve exit in the back.

In the human eye, however, the retina is structured in a very surprising way that is exactly the reverse. The receptors face backwards, and not only the nerve fibers that collect to form the optic nerve but also all of the blood vessels that nourish it are in front, where they block the view and cast shadows on the retina. The result is that the human eye has a large and seemingly unnecessary blind spot, and that very intricate processing by the brain is necessary to hide the image of the shadows of the blood vessels.

It all works, of course, but it is puzzling as to why an intelligent creator would design it this way, particularly given that the much older cephalopod eye does it the "right" way. No doubt it is possible to explain this (just as it is possible to explain fossils by saying that God created the fossils along with everything else in 4004 BC).

It seems much easier to explain this as a series of incremental adaptations rather than as being "designed" the way a human engineer would design a camera. Of course that does not mean that the incremental adaptations were necessarily guided by pure natural selection as envisioned by Darwin, either. Dpbsmith 14:01, 18 December 2006 (EST)

Reply: I don't know where you got the thing about creationists believing that God created the fossils in 4004 B.C., but I believe that the vast majority of fossils are the product of Noah's flood as it is described in Genesis. ChrisS

Reply: I believe that almost everything you say here provides evidence for creation. Let me explain... in you first paragraph you state that mammals "are strikingly similar in their general 'design'". This is true but does this support macro-evolution? I think not. Wouldn't macro-evolution produce many different types of "eyes" that would work? Why are they all so similar?

You go on to say that in the human the eye is just different from all these other eyes. You say this provides evidence against creation because, if it were true, why is it not the same as the others. Well, doesn't this also support creationism? Why would just one be different? Because our creator was original, he was an artist, not a robot. As for the "very intricate processing by the brain [that] is necessary to hide the image of the shadows of the blood vessels." This is more evidence for creation. Why would natural selection create a process like this? It seems pointless to us, but those "intricate" processes were intricately designed. Maybe our creator was trying to show that he existed... He created this one eye that wouldn't work; if it not for these amazing brain processes. PhilipB 15:11, 18 December 2006 (EST)

It's certainly a point of view... but didn't you feel that you needed to work just a bit to arrive at it?

Although it's certainly possible, I don't believe that God involves himself in the design details of vertebrate anatomy, and I certainly don't believe he goes to the effort of putting in deliberate design errors as a trick to test peoples' faith. I think a lot more likely that God created the general conditions under which evolution by natural selection takes place, and the "wrong" anatomy of the vertebrate retina is the result of the constraints of having evolved in gradual steps. Dpbsmith 11:48, 19 December 2006 (EST)

Reply: There is nothing to indicate that the human eye is an "error"; it works wonderfully. Also under the belief that God is omnipotent, I have no trouble as you do in believing that God would design the details of vertebrate anatomy, especially in light of the arguments against evolution below (with the possible exception of argument #7). Why would he let life progress at random when he could create every thing "fearfully and wonderfully" to reflect his awesome greatness?

BenjaminS

no...

If you have questions about Evolution/Creationism see the articles on this website [[3]]

I would just like to say that the "theory" of Evolution does not even qualify as a theory!! According to the scientific method, after you make a hypothesis, if ANY data comes up that contradicts you hypothesis than it must either be revised or discarded! How come even though there is much evidence that contradicts evolution it is still considered a theory? ChrisS

No: 1. No credible transitional forms (fossils reflecting evolution between species) have ever been found.

Counter Some transitional forms

2. There is no plausible explanation for the evolution of the whale, which is a mammal. Darwin suggested that the whale somehow came from black bears swimming with their mouths open!

3. Evolution cannot be reconciled with the evidence of a massive flood.

4. All mutations are harmful.

5. Species have being going extinct rather than being generated.

6. All unaided things become more disordered and scattered over time.

7. There is vast beauty in the world which would not exist in a purely evolutionary world. "The heavens declare the glory of God, and the firmament shows his handiwork" (Psalm 19:1)

8. Abiogenisis is impossible. Even the simplest life form possible would be way too complicated to spring from nothing.

No: In short... no. In long... there is much evidence against the theory that proves it is false. First of all there is the classic argument that the "missing links" are still missing. Here is what Darwin had to say on the subject.

"Geological research, though it has added numerous species to existing and extinct genera, and has made the intervals between some few groups less wide then they otherwise would have been, yet has done scarcely anything in breaking the distinction between species, by connecting them together by numerous, fine, intermediate varieties; and this having been affected, is probably the gravest and most obvious of all the many objections which can be raised against my views." (The Origin of Species, 6th edition, 1962, Collier Books, NY, p.462.)

Since when you are looking for data from the earth's history the first place you would look is the fossil record. What does the fossil record say? It says macroevolution never happened. There are even less documented "missing links" today then there were in Darwin's day. Obviously, macro-evolutionists want these "missing" links to be found desperately based on the elaborate measures they have gone through to try and fake the public out into believing one has been found. Take, for example, the famous Nebraska Man. He was supposed "evidence" for macro-evolution but in reality he was based entirely on a tooth from an extinct species of pig found among some ancient tools![4] This is only the beginning of the evidence against macro-evolution and I will be adding more to this edit as I get the time!
