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.

Which of the following evidence would support their hypothesis?


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


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


The two populations have different exoskeleton color patterns.


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