Divergencia

The video explains how isolation of species groups leads to genetic differences over time. It also discusses how local environmental factors can cause divergence among populations, even if they are not isolated, especially when spread over large areas.

What happens to two groups of the same species when they are isolated from each other?

• They become identical over time.

• They accumulate genetic differences.

• They stop evolving.

• They immediately become different species.

What is the primary focus of the first section?

• The effect of isolation on genetic differences

• The role of environmental factors in species evolution

• The impact of large areas on population spread

• The immediate effects of interbreeding

How can local environmental differences affect populations?

• They have no effect on populations.

• They make populations more similar.

• They cause populations to merge.

• They can lead to divergence among populations.

What is a possible outcome when a population is spread over a large area?

• The population becomes more uniform.

• The population decreases in size.

• The population remains unchanged.

• The population experiences divergence.

Which of the following is NOT a factor in genetic divergence?

• Isolation of species groups

• Local environmental differences

• Large geographical spread

• Immediate interbreeding
