@MadJW,
Before reporting your post for name-calling, I'll make one last (and probably useless) effort to explain natural selection. Two excellent examples are the woolly mammoth and the woolly rhinoceros. Both had a mutational propensity toward long and coarser hairs than other mammoth and rhinoceros. It did not hamper their reproductive opportunity, so there were always such individuals around. During the last ice age, that heavier hair favored them in exploiting the new environment arising from the periglacial conditions. Over tens of thousands of generations, individuals with much thicker hair had a reproductive advantage, and the woolly mammoth and the woolly rhinoceros became even "woollier." However, when the ice age came to an end, those heavy coats were not only no longer an advantage, they were a liability. So both species died off. End of story.
I see you as just a snide, ignorant individual who mocks others because you cannot understand, and precisely because you are ignorant. Everyone is, of course ignorant, because no one knows everything. The trick is not to shoot your mouth off about topics you don`t understand. Of course, you`ve also got that moronic god-did-it bullsh*t going on, too.
