You are correct. We should be very careful not to anthropomorphize evolution. It has no goal, no purpose. We use these words abstractly.
Well, because organisms are limited by the real world of physics, chemistry and biology. It would ne nice if they could simply operate perfectly until some major organ failed catastrophically, but evolution hasn't reached that stage yet.
Uh. Well, that's fundamental to the very concept. Organisms that can survive can reproduce to pass on their traits. But there's no goal of what traits might allow survival of the next generation. No thinking ahead. Let's try the other way. If it did have a goal, what do you think it might be?
In effect it leads to species that might be better suited to survive a given situation, but it's a passive process. Bad designs die out, good designs survive. Purpose requires a sense of the future, which evolution totally lacks.
I don't know I asked evolution why it did not have intelligence Shrugged its shoulders and said Don't know
But of course We've been best buddies ever since he teamed up with Darwin Why do you think I live in Darwin?
