It's pretty much all we have going for us. An animal half our size (a dog, for example) can kill us easily in a physical match. Even our method of locomotion (slamming our weight down on the heel and transferring it to the ball) is kinda dumb.
In regards to an animal half-, same-, or treble-our-size (and MUCH larger), some cases this is true; in other cases it is absolutely false.
Many animals can be outwitted and can be eliminated by superior intellect and even simple tool use. We weren't around to see out forefathers trick mammoths into running off cliffs, or slaying them with at-latls (javelin throwers that magnify the velocity of a hurled javelin). Be we did it all the time with bone and stone implements. Or a bit of leather cord, a woven pocket, and a smooth stone can also be turned into a lethal implement, felling targets at range before they know we're there.
Most would agree that a German Shepherd is a formidable foe against a non-combat-trained human, but with simple neck-kicking techniques, our WWII boys managed to eliminate them without wasting ammunition and making noise. Cleverness beats physical superiority.
There are many other examples that can be stated here, but I think you get the idea; Although intellect takes preparation to be put into use (combat training, ambush, building simple tools, etc), it usually kick tha arse of pure physical superiority.
If you get a chance, watch "The Jagged Edge", where a party of men are hunted by a humongous bloodthirsty bear. One man who was familiar with the past managed to defeat what seemed to be unbeatable odds. A great lesson for our kids.
