El origen de la especies

The video explains how species have evolved over billions of years, forming a diverse array of life. It describes species as populations that are reproductively isolated and how new species form through evolutionary processes. Geographical isolation, such as mountains and rivers, can lead to speciation by dividing populations and driving genetic differentiation. Natural selection further enhances these differences, leading to new species. Speciation is typically slow but can accelerate with rapid environmental changes.

What role does natural selection play in the differentiation of species?

Explain how rapid environmental changes can affect the process of speciation.
