Speciation and Extinction

The video explores the concepts of speciation and extinction, explaining how species evolve into new ones or disappear entirely. It uses examples like the Tapuiasaurus and the three-spined stickleback to illustrate speciation. The video also discusses adaptive radiation, where species rapidly diversify, and mass extinctions, highlighting the K-T extinction event that led to the disappearance of dinosaurs. The interplay between evolution, environment, and these processes is emphasized.

Discuss the impact of human activity on species extinction as mentioned in the video.
