b. the animals use exactly the same traits to identify appropriatemates.
c. differences in these traits caused
d. the adaptive value of these traits can be explained.

Which of the following most likely demonstrates that classification is the basis of evolutionary relatedness?
A. Organisms that share similar characteristics are impliedly understood to have common ancestors, thus having an evolutionary relationship.
B. Classification is to organize organisms into groups based on their differences and similarities and evolutionary history, so as evolution changes, classification will also change
C. Classification based on evolutionary relatedness always infer that all organisms that evolved similarly shares the same history.
D. Homologous structures among organisms depicts the same evolutionary history or paths.
All of the following are true about phylogenies, EXCEPT:
a.
They are considered an unbiased reconstruction of evolutionary relationships.
b.
We use them to predict the emergence of traits in the fossil record.
c.
They are, at best, a hypothesis about the relationships among extant species.
d.
We use the rule of parsimony to reconstruct evolutionary history.
