We need to clear one or two things up here. Evolution by natural section has nothing to do with the favouring or disfavouring of individuals within a species. Natural selection is concerned with the non-random (think about it) survival - survival - of heritable traits (as Darwin might have said) or genes (as we might say) within gene pools. The weakest and slowest wildebeest might well be the one caught by the lioness, but don't jump to conclusions here. That poor beest might have got caught because it was a bit older and therefore slower, or because it had an injured back leg, or because it was lumbered with a huge foetus inside it. Nothing there to do with genes. That poor thing might well have lived a full reproductive life before it got caught. Its genes will go on and on. The only way its genes will not go on and on, or go on and on a bit less, is if it gets caught young, or is somehow a bit less appealing to males. Discuss! Let's counsel against being simplistic. Please read "Origin" cover to cover. Especially before you bombard me with PMs telling me how I'm getting it so "tactically" wrong apropos of idiot pete. Honestly, guys, he doesn't matter.
