What is a Population?

The video explores Earth's biosphere, ecosystems, and the concept of populations in biology. It discusses how populations form, often through isolation due to geographic barriers or human activities. Isolation impacts genetic diversity, leading to less varied gene pools. The video also covers the effects of catastrophic events and human development on populations, highlighting genetic bottlenecks and their consequences. It concludes with the role of population biology in species evolution, explaining how genetic changes in isolated populations can lead to new species.

Explain the concept of genetic bottlenecks and their significance.
