The Origin of Species — Speciation, Reproductive Isolation, and Hybrid Zones Explained | Chapter 24 of Campbell Biology Welcome to Last Minute Lecture! This post unpacks speciation and the formation of new species, as covered in Chapter 24 of Campbell Biology . Learn how reproductive isolation leads to genetic divergence, what defines a biological species, and how allopatric and sympatric speciation create Earth’s biodiversity. Watch the full video summary below and subscribe for clear, chapter-by-chapter biology study guides! Introduction: What Is a Species? Speciation is the evolutionary process by which new species arise, bridging microevolution and macroevolution. The biological species concept defines a species as a group of populations whose members can interbreed and produce viable, fertile offspring—but not with other such groups. The emergence of new species (speciation) is key to understanding the unity and diversity of life. Reproductive Isolation: Barriers to...
