Logically,which of the following should cast the most doubt on the relationships depicted by an evolutionary tree?
A)Some of the organisms depicted by the tree had lived in different habitats.
B)The skeletal remains of the organisms depicted by the tree were incomplete (in other words,some bones were missing).
C)Transitional fossils had not been found.
D)Relationships between DNA sequences among the species did not match relationships between skeletal patterns.

Question

Quizplus · Accepted Answer

DNA sequences are considered more reliable indicators of evolutionary relationships than morphological features such as skeletal patterns, so if there is a mismatch between the two sets of data, it should cast the most doubt on the accuracy of the evolutionary tree. A and B may introduce some uncertainty, but they would not necessarily contradict the relationships on the tree. C, while important, is not as essential to the accuracy of the tree as the other factors mentioned.
