Population genetics helps us learn how species change and adapt over time. Here are some key ideas:
Gene Variability: There are different versions of genes, called alleles. This gives species a variety of traits. Some traits may help them survive better in changing environments.
Natural Selection: Some traits are more helpful than others. When we look at Peppered Moths during the Industrial Revolution, we see that their darker color helped them survive better in polluted areas. Over time, more moths developed this favorable trait.
Genetic Drift: Sometimes, random changes happen in a population. These changes can create big differences, especially in smaller groups of animals or plants.
All of this shows how genetics and evolution work together in nature!
