Selection and Speciation

The three species pictured do not share a common ancestor, yet have evolved to have a similar anatomy and life style. This is an example of ?

• Homologous Structures

• Divergent Evolution

• Vestigial Organs

• Convergent Evolution

• Extinction

• Coevolution

• Convergent evolution

Bursts of change followed by periods of stability.

• Punctuated equilibrium

• Gradualism

• Extinction

• Speciation

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

The three species pictured do not share a common ancestor, yet have evolved to have a similar anatomy and life style. This is an example of ?

• Homologous Structures

• Divergent Evolution

• Vestigial Organs

• Convergent Evolution

Convergent evolution is when

• Species share traits due to a common ancestor

• Species have similar traits because of similar environment

• Species have same traits due to different environments

What is allopatric speciation?

• Species occupy different roles in the habitat.

• Species mate at different times of the year.

• Populations become geographically or physically separated.

• Populations diverge in the same location, but can no longer reproduce together.
