Using the cladogram:  a common ancestor of amphibians and ray-finned fish would have

• a bony skeleton
• four limbs
• scaly skin
• eggs with shells

The condition in which there are barriers to successful interbreeding between individuals of different species in the same community is referred to as 

• sexual dependency
• reproductive isolation
• geographic isolation
• adaptive radiation

The wing of a bat and a humans' arm have different functions and appear very different.  Yet, the underlying anatomy is basically the same.  therefore, these structures are examples of

• geographic isolation
• analogous structures
• homology
• reproductive isolation

• 16 percent
• 32 percent
• 48 percent

The differences in sparrow songs among sympatric species of sparrows are examples of

• geographic isolation
• convergent evolution
• behavioral isolation
• mechanical isolation

NGSS.HS-LS2-8

Two allopatric species of sparrows have very similar niches when compared to two sympatric species of sparrows.  What would be a good explanation for this?

• The allopatric species have no competition with one another so therefore can occupy similar niches
• The sympatric species are usually mechanically isolated from one another
• The sympatric species diverged from a common ancestor
• The allopatric species are behaviorally isolated from one another
