One crucial question my friend asked me, "How come not all Chimpanzees evolved to humans if Darwin's theory is not a flawed one?".
A quick Google came back with relatively diverse articles and it is quite confusing as to speak.
I was refreshing my knowledge about common ancestor, what-not the flaw of pentadactyl and biochemical/molecular argument and the over emphasize on homology.
Right at the end of this particular article however,
It is hard to resist the conclusion that something must have happened to the ancestors of Homo sapiens which did not happen to the ancestors of gorillas and chimpanzees (1989, pp. 17-18, emp. added).
That “something” actually is “Someone”—the Creator.
To be honest, I lol-ed at the very last line, which is not part of a quote but rather the writer's opinion. The author used the word "actually" rather than "could be".
My question is, errr.. how exactly you knew that?
Anyway, back to the initial Q. I would settle for the "The discovery of the skeleton of an early human, who lived 4.4 million years ago, shows that humans did not evolve from chimpanzee-like ancestors" argument. They argue that the common ancestor has to be pushed back further than chimpanzee, humans did not evolve from chimpanzee-like ancestors.
So lets reframe the Q, what is the common ancestor of chimpanzees and humans rather than humans evolved from chimpanzee.
Evolution is not a straight line, where entire populations change into new species all at the same time. Often times, a small group breaks away from a population and begins to evolve independently of the source group. The source group does not need to go extinct, and is generally unaffected by the development of the smaller group. This is called "Allopatric Speciation," and it is just one of many ways that new species can evolve.
