Difficult

Separated Populations

APBIO-GZBWWR

A dam is constructed on a river, leading to the formation of a large reservoir. A population of beetles is separated into two populations that no longer have any contact with each other.

Several hundred years later, a scientist hypothesizes that the two beetle population have become different species.

What evidence would support their hypothesis?

A

A Cytochrome C protein comparison reveals that there is only one amino acid difference between the populations.

B

A DNA comparison reveals that the DNA of the two populations is 99% identical.

C

The two populations have different exoskeleton color patterns.

D

When members of the two populations are combined in a lab setting, they do not interbreed.
