Three different bird species are represented by the letters R, S, and T. Species S and T show similar coloration. The enzymes found in Species R and T show similarities. Species R and T also exhibit many of the same behavioral patterns. Which figure best shows the relationship between species R, S, and T?

Answer 1

It is likely that Species R and T are more closely related to each other than to Species S. Therefore, the relationship between the three species can be represented as follows:

R ---- T
\ /
\ /
S

This shows that Species R and T are more closely related to each other compared to Species S.
