Welcome to this comprehensive lecture on Adaptive Radiation, a crucial topic in Evolutionary Biology for Class 12, NEET, and CUET 2026 aspirants. In this video, we break down how a single ancestral species can rapidly diversify into a variety of forms to fill different ecological niches.
What You Will Learn:
Definition of Adaptive Radiation: Understand why this process is considered a type of divergent evolution.
Darwin’s Finches: The classic story of how birds on the Galápagos Islands evolved unique beak shapes based on their feeding habits (seeds, insects, or cactus).
Australian Marsupials: How a variety of marsupials (like the kangaroo, Tasmanian wolf, and koala) evolved from a single ancestral stock within the isolated Australian continent.
Trigger Factors: Why environmental changes, new habitats, and mass extinctions (like the end of the dinosaurs) spark these "evolutionary bursts."
Adaptive Radiation vs. Convergent Evolution: Learn the difference between these two concepts and how they relate when multiple radiations occur in the same area.
