Natural Selection: Survival of the Fittest (Part 5)

What You'll Learn

Adaptations develop over many generations through natural selection. Structural adaptations (like thick fur), behavioral adaptations (like migration), and physiological adaptations (like venom production) all help survival.

Key Words
