I was, in answer to your following critique...Barbarian observes:
Those aren't contradictory. The first merely gives the scientific definition, and the second gives the consequences. Evolution is a change in allele frequency in a population. Speciation is a consequence of that change. Evolution can happen without speciation.
It cites Darwin's theory, (and says so) which is not current evolutionary theory. Darwin merely noted natural selection produced descent with modification. Modern evolutionary theory adds Mendel's discovery.
Which is true. But the proper scientific definition is the one I gave you. Has been since the "modern synthesis following the re-discovery of Mendel's work.
It's the precise definition for Darwin's theory. That theory has since been modified to include genetics. And it correctly states that it's Darwin's theory that is being defined.
Don't think so. You were, I thought, arguing that those two different things were not being properly defined. As you see, they are.
Pleased to clear that up. Darwin's statement is quite correct; it merely doesn't add the findings of genetics, which cleared up a difficult problem for his original theory. The four basic points of Darwinism are observably true, of course.

So you agree that "On the Origin of Species" is one of those "sources that don't have much to do with science". I give you too little credit, apparently.Yep.
Yes, there we are...and I was really beginning to think highly of your posts--not agreeing with the content, but at least acknowledging that you write and research them well.Barbarian observes:
Don't think he called it "evolution" though. Everything I've read from him called it "acquired characteristics."
...
Ah, The Descent of Man came later. So there you are.
Great bait and switch technique. Somewhere, somehow, organisms must gain complexity in order for evolution from one organism to another. You can't start with a single-celled creature and end up with a system-of-cells creature without gaining some complexity. IT CAN'T ALL BE DUE TO LOSS OF FUNCTION or the first creatures would have been the most complex, and Darwin knew it.But by "progression", he meant fitness, not complexity or "higher" organization. Indeed, in his chapter on rudimentary organs, he discussed how organisms might lose functions through evolution.
Now, it could be that all that we see today is a loss of function, sometimes allowing a slight benefit in fitness. You really want to hang the whole hat of evolution on only the "directly observed"? Not that I disagree--that is really all you have. Everything else is an alternate creation myth.
Loss of function, then, gets back to that word "descent", doesn't it.
Because those scientist have convinced themselves that they are right, despite falling for their own illogic. Creationists are not the only presuppositionalists.Usually, because they don't listen. And, so many creationists spend much time and energy fighting an enemy they have themselves constructed while amused or bemused scientists watch the proceedings.
