Theory of Evolution

Definition

The scientific explanation for the diversity of life, proposing that species change over time through natural selection and genetic variation.

Key Features

• Natural Selection: Traits that enhance survival are passed on to offspring.
• Genetic Variation: Differences in DNA drive adaptation.
• Common Descent: All life shares a common ancestor.

Real World Examples

• The development of antibiotic-resistant bacteria through natural selection.

Applications

• Medicine: Understanding disease resistance and vaccine development.
• Conservation: Identifying and preserving species at risk.
