We still remain in second place for muscle density out of all the species on this planet, beaten out only by the chimpanzee.
What does that mean? That we're the second strongest animal, pound for pound? If yes, I'd like to see you wrestle a black bear into submission, they're only slightly heavier than humans.
No. It means that we have the highest muscular tissue density. We're second strongest pound for pound of
muscle tissue. Black Bears have more muscle tissue than us, but only by that feature is a black bear stronger than a human. Plus, the teeth, jaw strength, size, and claws help to make wrestling them unarmed difficult in the extreme.
Point is, humans are weaksauce for our size. That's because we're not built for power but rather for endurance. And we're pretty damn fuel-efficient, as large mammals go.
We are, in fact, Game Breakers for our size, even though we are built for endurance before power. The whole "Now dominate the entire planet." thing is fairly decent proof of that. In strength by weight, we're stronger than every species besides the chimpanzee, who are about 10% stronger per pound.
Humans are not weaksause in any area except natural disease resistance, and we're using technology to make that not a problem. Which means that, yes, humans are now the munckins of the world. It's a good thing animals can't talk, or they'd be ragequitting on us all the time.
