And by the way: It is not “survival of the fittest.” It is “survival of the sufficient”. You only have to be just fast enough, just strong enough, just smart enough, etc. to survive. If the gazelle would evolve to be faster, the cheetahs would go hungry. If the cheetahs would evolve to go faster, they would be prolific and consume their main food source. If they evolved speed together, tit for tat; then they would be supersonic by now.
BTW, creation allows for changes within an animal group. Darwin utterly fails because of no transference between major animal groups.
And therefore, monkeys change into chess-masters.
Fittest does not solely mean fastest. It also means healthiest and smartest, among other things, so your supersonic supposition is off-base.
” You only have to be just fast enough, just strong enough, just smart enough, etc. to survive. “
No. the only requirement is that you reproduce at least as fast as you die.
