Molecular studies have changed many of the phylogenetic relationships previously identified by morphological studies. These changes indicate that ________.
A) molecular and morphological studies rarely agree
B) molecular studies add additional information to morphological studies and improve our understanding of evolutionary history
C) molecular studies are less reliable than morphological studies
D) molecular studies are extremely time consuming and expensive and really don't add additional information to our understanding of evolutionary history

Question

Quizplus · Accepted Answer

Molecular studies provide additional genetic information that can reveal more accurate relationships between organisms than morphological studies alone. The combination of both types of data can lead to a better understanding of evolutionary history. It is important to note that molecular and morphological studies can sometimes disagree, but this does not negate the value of either approach. Additionally, while molecular studies can be time consuming and expensive, they have become increasingly accessible and affordable as technology has advanced.
