The idea is that this one review paper provides citations to the primary research - I was trying to make it easy for you.

Re: Re:

All DIRECT evidence of evolution available to date is evidence of gene LOSS. Yet again, I'd like to see citations that show that "ALL direct evidence of evolution available to date is evidence of gene loss," not just you cherry-picked citations. If you don't like these inferences, please ...

Don't you just love it when someone is trying to debunk evolution, yet they obviously don't know anything about it? And when you show them how they are wrong, they continue to argue.... I have wondered why it is that they think that they are qualified to make this criticism? Do they tell a physician...

Re: Evolutionary mechanisms

Since natural selection tends to reduce variation does it also hold true at the ecological level in fauna flora interactions? Using cat's example of slow rabbits getting eaten and reducing variation of this species, will this help increase variation of certain plants since there will no longer be c...

Re: Evolutionary mechanisms

Male birds of species X have bright plumage because those individuals that had it (ancestors) propagated more than those that did not have it. There is no way to prove it since there are no males without bright plumage today. What?????? Sexual selection (one sex selecting the other based on traits)...

Re: Re:

That most mutations are harmless. That wikipedia page talks about one gene: the major histocompatibility complex, class II, DQ beta 1, also known as HLA-DQB1. One gene does not demonstrate "that most mutations are harmless." Earlier, I wrote that "most mutations are harmful and/or ne...

Re: Re:

You are right and wrong at the same time. Translocation and duplication take place - fact. This can result in a new trait - fact. However, we talking about the SAME (already present in the gene pool) DNA material. "This extraneous DNA, if further modified can become an entirely new gene that p...

Re: A little help

1) All life came from a single specimen? Probably. 2) All evolution stems from random mutations? (random being the key question here) Yes. Those random mutations are then selected for or against. They may also be neutral but subject to future selection. 3)Related to question 2, but environment does...

Re:

I just find the title of this thread hilarious. It would be like asking, "Is rocket science as simple as we think?!" Admittedly, evolution is, at its heart, a deceptively simple idea, but the implications are endlessly complex and fascinating. You're right about evolution being a simple c...

Re: Re:

Genes/alleles were always there in the gene pool. No, they got into the gene pool via mutation. They were retained in the gene pool because they were either beneficial or neutral. Thanks. I will retract word "always". I meant to say "Genes/alleles were already there in the gene pool....
