What is evolution? What is it you think drives evolution? Who do well in evolution and who get weeded out and why? Some kind of answers to those questions will solve much of the mystery.  |
If plants and animals evolve in response to the changes in the biosphere; like a change in climate, maybe an introduction or disappearance of flora and fauna that would totally alter their way of life, thus creating a change of their position in the food change or eating habits, like evolving to elude beig eaten, or evolve to be harder, better, faster, stronger plant and/or animal etc. So if plants and animals evolve because they have to adapt, human don't have to the changing world around them humans can alter the habitat they live and create tools, instead of adapting on the genetic level like plants and animals, so why would they have to evolve - it would be a mute point.
Cheetas are lean mean hunting machines, they evolve to run fast, and take out their prey, on the other hand human don't have to evolve for speed they can just create say a bow and arrow right to hunt and kill, right? That would deminish the need to evolve into a fast running species or some subspecies of super fast humans who can chase after prey, while the rest of the species would live a more sedentary lifestyle as like being hunter/gathers or into some kind of husbandry.
Some scientist once siad that the human race could not survive as a species if it wasn't for their intellect. He point out that humans aren't the fastest, or the strongest, and without the domiciles they know how to build, and the clothes they know how to make, the human species would not be suitable to live all over the world like they actually do.
So in short it's human's intelligence that stops us as humans from evolving.
