I think the problem for megafauna was being relative easy targets for human
projectile weapons and hunting tactics. It seems like the mega in megafauna
was an adaptation both for heat regulation but also defense against
predators. The entry of humans into the ecosystem upset all that -- because
being big no longer had the same impact.
I'm not sure, though, any predator really wouldn't take more than its fill.
Yes, say, a big cat will probably not continue to hunt until a whole herd
is decimated if it's already taken enough to eat for the duration, but it
will breed until something checks further expansion, no? It's just that big
cats, to stick with this example, usually are not as proficient as humans
here, no? Certainly not with regard to something like the megafauna.
