• convergent evolution
• coevolution
• speciation
• adaptive radiation

What is convergent evolution?

• evolution toward similar traits in unrelated species
• evolution toward different traits in closely related species
• elimination of a species from Earth
• the rise of two or more species from one existing species

Sharks and dolphins both have streamlined bodies that allow them to move through water efficiently, this is an example of which type of evolution?

• Divergent
• Coevolution
• Convergent
• Artificial

In convergent evolution, organisms share physical similarities because they 

• have a common ancestor
• live in similar environments
• develop homologous structures
• are closely related

Two organisms change in response to each other forming a specialized relationship.

• Coevolution

• Convergent Evolution

• Gradualism

• Extinction

What describes a group of organisms that can interbreed and produce fertile offspring?

• species

• speciation

• population

• hybrid

What describes a group of organisms from the same species living in the same area?

• species

• speciation

• population

• hybrid

________ can cause speciation when a population becomes separated from each other due to a river. The 2 populations evolve to become 2 different species.

• reproductive isolation

• temporal isolation

• geographical isolation

• sympatric isolation
