That's only worked with one species, it's not going so well for the rest. How many hominid species even exist now? 4 or 5? If humans could not talk we would be done for, though Neanderthals could talk I think.

I don't think they can migrate that fast and many animals like zebras probably can go faster maybe even tigers, tigers still travel long distances because they have long ranges. Cats also adapted to pretty much every climate too but that is generally different species I suppose whereas humans can go everywhere. Though the domestic cat itself is actually fairly versatile, they are one of the most widespread animals in Australia, even more so than foxes(foxes don't seem to like the tropics).

Humans can build boats and rafts and use them to travel further though.

That just shows how weak they are and it often does not work anyway, that leopard just doesn't look hungry.
