Beth Shapiro and other researchers studying the history of organisms have long urilized andent DNA-DNA recovered from anclent organic material that has been preserved under natural conditions. However Lee Hslang Liow and colleagues' 2020 study of the evolutionary relationships between thirty seven species of metazoans Instead relled on historical DNA-genomic data uncidentally preserved in speciment that are housed in natural history collections-this capitalizing on the research potential offered by a wast but hitherto relatively understhiked source of finsight into the biological past. for Review Which choice best describes the function of the underlined portion in th A It specifies potentinl applications of the approach that Llow and in their study. B It offers commentary on the significance of the approach that I. colleagues used for their study C It explains why the research methodology selected by Llow and widely used. D It emphasizes the importance of Llow and colleagues' findings metazoans.

## Step 1
The problem is a reading comprehension question, which requires understanding the context and the role of the underlined portion in the sentence. The underlined portion is "this capitalizing on the research potential offered by a vast but hitherto relatively understudied source of insight into the biological past."

## Step 2
The sentence is discussing the research methodology used by Liow and his colleagues, which involved using historical DNA preserved in specimens. The underlined portion is explaining why this methodology is significant.

## Step 3
The underlined portion does not specify potential applications of the approach (option A), nor does it explain why the methodology is widely used (option C). It also does not emphasize the importance of Liow and colleagues' findings (option D).

## Step 4
The underlined portion is providing commentary on the significance of the approach used by Liow and his colleagues. It is explaining why this methodology is important and why it is a significant contribution to the field of study.
