Have you ever observed crows? They’re very intelligent according to a lot of studies. If you observe them for some time, you’ll notice how the intelligence gives them an edge. Basically, crows will try and steal from every other species around. Mostly food, but also other stuff they deem useful.

Now, with that knowledge, observe humans. The early humans also stole stuff from every other species. You could also argue that the most successful humans (in terms of wealth) also tend to steal everything, but that’s beside the point, just view those as lagging in terms of evolution.
