Definition: Natural selection is the process where individuals with traits better suited to their environment survive and reproduce more, passing those traits on.
Examples:
- Dark moths became common on soot-darkened trees because birds more easily spotted and ate lighter moths.
- Some bacteria survive antibiotics due to resistant mutations and then reproduce, making the population resistant.
Sentence using it: Natural selection helped polar bears develop thick fur and white coats to survive in the Arctic.
