Natural Selection

Imagine a race where the fastest runners get a gold medal and a snack, but the slowest runners don't. Because the fast runners are healthy and strong, they have kids who are also fast runners. Over a long time, everyone in the family becomes a great runner. This is how nature picks the best "tools" for animals to stay alive.

You are a living collection of "winning" traits. Every breath you take is a "thank you" to the billions of ancestors who were fast enough, smart enough, or tough enough to pass the baton to you.

Natural Selection operates as a non-random filter on random genetic variation. It is the differential survival and reproduction of genotypes. By modulating allele frequencies within a population's gene pool, it optimizes "fitness." It connects to Game Theory, where strategies yielding the highest payoff (survival) become the dominant Nash Equilibrium in a biological ecosystem.

SOUND: Listen to bird calls in a forest; the ones heard over the wind are the ones that survive to find mates.

SMELL: Smell a flower. It smells sweet specifically to trick a bee into visiting so the flower can make seeds.

TASTE: Bite into a sour lemon. That "zing" is the plant's way of saying "don't eat me yet."

TOUCH: Feel the thick fur of a dog. That fur is there because his ancestors would have frozen without it.

SIGHT: Look at a green grasshopper on a green leaf. It is "invisible" so it doesn't get eaten.

BODY: Balance on one foot. Your ability to stay upright is a "tool" honed over millions of years.
