• Mutation

Which types of natural selection lead to speciation?

• Stabilizing, directional, and disruptive

• Directional, disruptive, and artificial

• Disruptive, stabilizing, and sexual

• Artificial, sexual, and stabilizing

How has evolution influenced the world?

• It has had no significant impact.

• IIt has increased biodiversity.

• It has only influenced the animal kingdom.

• It has decreased biodiversity.

What can different types of isolation amongst a species lead to?

• Extinction of the species

• Formation of a new species (speciation)

• Decrease in genetic diversity

• No change in the species

Based on the diagram, which anatomical part of the horse shows significant changes over time?

• Tail

• Tooth

• Mane

• Hoof

What type of selection favors the intermediate phenotype over the extremes?

• Directional selection

• Disruptive selection

• Stabilizing selection

• Sexual selection

What does disruptive selection favor in a population?

• Intermediate phenotypes

• Both extreme phenotypes

• Only the most common phenotype

• Phenotypes that are not present in the population

What can cause a population to become geographically isolated?

• Urban development

• Mountains, islands, etc.

• Climate change

• Overhunting by predators

What is a likely outcome when a species is geographically isolated?

• The species will not meet any environmental challenges.

• The species will evolve in the same way as the original population.

• The species will meet different environmental challenges and evolve independently from the original population.

• The species will go extinct.
