Answers
Explanation:
answer is Natural selection.
Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others.
Darwin's process of natural selection has four components.
Variation. Organisms (within populations) exhibit individual variation in appearance and behavior. ...
Inheritance. Some traits are consistently passed on from parent to offspring. ...
High rate of population growth. ...
Differential survival and reproduction
Natural selection is still happening in humans
In some countries, the population has acquired 'lactase persistence', meaning that people make lactase throughout their lives. In European countries we can thank one specific gene variation for our lactase persistence, which is called '-13910*T'.
