Note I said nothing about "survival of the fittest", which as you say is a poor explaination of the process of evolutionary change. Any examination of that process actually shows something more, as you say again, mutual. A bird has no need for better eyes if that bug he eats doesn't develop better camoflage nor does the bug need anything better if the bird's eyes don't get better.
If you will limit this to humans only, I will say deep thinking, indeed. We are the only creatures known to educate. It is fine distinction for some but, watching the mother Lion hunt and then the cubs try to figure it out, is not educating. They are allowed to watch. Some don't get it.
Nope, apes that have been taught sign language (or was it chimps) have been seen teaching their children american sign language.
Education is but a form of mutual aid.
Actually, an evolutionary arms race is an example of competitive natural selection. I think you're looking for interspecies mutual aid. I'm talking about behavior in the evolutionary sense. Let's keep this coherent, you said that capitalism resembles nature, I explained that according to nature, cooperation is by far a better strategy than competition. We don't conduct capitalism with other species. Or maybe we do, maybe that is the problem.
Not really, no. Sure some collaboration between parties with temporarily aligned interests, but other than that, it's all competition, creating more losers than winners.
So are Zebra stripes.
