Origin of Species

The video explains how life evolved from simple organisms to a diverse array of species through speciation. Speciation occurs when populations become reproductively isolated, often due to geographic barriers, leading to genetic divergence. Over time, adaptations to different environments result in new species. While speciation is typically slow, rapid environmental changes can accelerate the process, causing a burst of new species.

Describe how natural selection contributes to the divergence of species.
