How can you tell two species apart? It’s not always simple. In this episode of Crash Course Biology, we’ll learn about speciation—a process that can happen over millions of years, or within a single generation. Along the way, we’ll discover how a single species can split into two and how a reptile from New Zealand continues to stump scientists.

Chapters:

A Living Fossil 00:00

Species & Evolution 2:16

Species Concepts 3:36

What Separates Species 5:40

Allopatric Speciation 6:52

Sympatric Speciation 8:38
