Convergent and Divergent Evolution.

When unrelated species evolve similar characteristics because they live in similar

environments

• Divergent Evolution

• Speciation

• Convergent Evolution

• Punctuated equilibrium

Species from the same ancestor accumulate differences over time since they live in different environments

• convergent evolution

• divergent evolution

• co- evolution

Species that are not related develop similar features since they live in the same environment.

• convergent evolution

• co- evolution

• divergent evolution

Shows how different groups of organisms have changed over time.

• fossil record

• homologous structures

• embryology

A trait or change in lifestyle that helps a plant or animal survive in its environment

• adaptation
