Comparative Anatomy: What Makes Us Animals - Crash Course Biology

The video introduces comparative anatomy using a zebra finch named Shoshana to explore similarities and differences in animal anatomies. It discusses animal characteristics like locomotion and heterotrophy, and explains convergent evolution with examples of marine animals. The video highlights Thomas Henry Huxley's contributions to evolutionary theory and examines animal tissues and organ systems. It concludes with an invitation for further learning and engagement.

What is the primary reason for studying comparative anatomy?
