Evolutionary Advantage

Nature is a conservative mistress and will often not imbue its creation with features that do not serve a purpose.

Human beings can see a wide spectrum of colors, for example, because we eat a wide variety of foods including fruits, nuts, and meat and this allows us to see easily when it is ripe or spoiled.

This is often exploited by fast food companies which use bright reds and yellows to trick our brains into eating more. Ever notice how much red and yellow there is in your usual hamburger joint?

It's a fun game to play, observing why different adaptations came to be. The way our ears are shaped helps us determine where sounds come from.

Our eyes on the front of our heads give us stereoscopic vision and allow us to gauge distances. The tendons in our feet and legs make us fantastic long-distance runners.

Loud noises startle us and get our adrenaline pumping in case we need to run to safety.

One thing that's universal among humans as well is what is known as the uncanny valley which is the discomfort and fear felt by humans as representations of humans approach (but don't

quite reach) reality. I wonder why, in our history, we evolved such a powerful aversion to things that looked very much like humans but clearly were not.
