Topic 1 Evolution: Patterns of Evolution

Question 1

• This type of evolution occurs when two or more species that originated from a common ancestor become increasingly different over time as a result of speciation.

Answer 1

Divergent Evolution

Question 2

• This type of evolution occurs when two unrelated species evolve to share more similar traits due to adapting to a similar environment (analogous traits)

Answer 2

Convergent Evolution

Question 3

• This type of evolution occurs when two related species make similar evolutionary changes after their divergence from a common ancestor

Answer 3

Parallel Evolution

Question 4

• This evolution occurs between two species. Each causes the other one to evolve, which results in the evolution of both species. An example of this is the coevolution of predators and prey, where the evolution of a more effective predator will cause the prey to evolve better ways to defend itself

Answer 4

Coevolution
