Animals should be eating us left right and centre because essentially, humans are weak save only thier intellectual capacity.
Well, that and our innate viciousness, ability to throw rocks, and capacity to run all damn day until the antelope keels over from exhaustion.
We are the weaponized ape, the best hunters and fighters ever born, the only proof of which I need offer is that we have the leisure time to have this conversation.
Look, human's arent all that special, you are disillusioned to the fact we are the best fighters and therefore the most able and best in general, a chimpazee is way stronger, vicious and can throw rocks and use simple tools aswell as co-ordination in attacking and can outrun a human. A primitive ape runs rings around "weaponized" brainy ape.
Imagine a elephant with the stature of a chimpanzee or ape, increase the population of this particular elephant species and brain capacity and eventually they would become a major threat if left un-noticed, by picking up where we left off at modern day forming thier own identity they may even overtake humans and make the same claims on how great they are.
Disadvantaged only by thier low adaptability they would overpower the human race with thier intellect, senses and brute strength.
