Divergence

The video explains how species evolve within populations. It discusses the role of reproductive isolation in accumulating genetic differences between groups of the same species. Additionally, it highlights how local environmental factors can lead to divergence in populations that are not isolated, especially when spread over large areas.

What is the primary focus of species evolution?

• Ecosystems

• Populations

• Communities

• Individual organisms

What happens when two groups of the same species become reproductively isolated?

• They become extinct

• They merge into one group

• They remain identical

• They accumulate genetic differences

Which factor can lead to divergence in populations that are not isolated?

• Local environmental differences

• Climate change

• Genetic mutations

• Predator presence

How does a large area affect population divergence?

• It causes extinction

• It has no effect

• It prevents divergence

• It can enhance divergence

What is a possible outcome when populations are spread over a large area?

• Increased genetic diversity

• Uniformity in genetic traits

• Decreased population size

• Immediate extinction
