Artificial Selection Breeds Organisms for Human Goals, Not Survival

In artificial selection, humans choose which individuals reproduce, based on traits useful to people.
This differs from natural selection, where the environment decides which traits spread.

How Selective Breeding Works

Identify a desirable trait, such as high milk yield, disease resistance, or fast growth.
Allow only individuals with that trait to breed.
Repeat over many generations, so the trait becomes stronger and more common.
