Competition of resources causes us to battle for them, and by this nature selects who's the most fit. But by fitness I'm not talking about who is the strongest, ants can lift 100x's their weight, no human can do that but yet we can crush an ant and think nothing of it. There is also the example of dinosaurs who were one of the strongest and biggest animals on Earth. It is proven by their extinction that they weren't fit for their environment so they were killed off. Also fitness isn't shared genetically, just because your parents were smart doesn't mean that you are going to be just as smart. This is where Nature vs. Nurture comes in. Your parents might play the guitar, that doesn't mean automatically that you are going to love guitar, but because you have been around the guitar all your life you might pick up an intrest from your surroundings.

Just for the record, I would like to point out an exaggeration. Ants can, at most, lift approximately fifty times their weight. The reason why human cannot do this can be explain as such: Mass increases as a cube of length, while muscle mass increases as the a square of length. This means that if a person were to grow 10 times taller, they would be 1,000 times heavier but only 100 times stronger. As such, more of the individual's muscles must work on holding up the heavier mass. Creature A, weighing 1 ounce, would have an easier time lifting 2 ounces (twice its weight), than a 100 pound creature would have lifting 200 lbs. Despite the proportion of 2:1 in both of these cases, the latter still has to lift less weight, as one hundred pounds is 1600 times heavier than one ounce.
