hmm... still i'm not sure. i mean, dogs seem like a good example, except i don't know exactly how much 'brains' they have. insects then? still, very little idea. umm... maybe shellfish? or shrimp? crawfish? dude i seriously don't know, but i might look into it. what it might be is that it has to be the right KIND of brain goo, not just the quantity. like, elephants have bigger motion areas or something... know what i mean? whereas humans have bigger.. lobes is it... so we can do abstract thought better.
