Text
Beth Shapiro and other researchers studying the history of organisms have long utilized ancient DNA—DNA recovered from ancient organic material that has been preserved under natural conditions. However, Michael G. Campana and colleagues’ 2017 study of the evolutionary origins of a fungal pathogen affecting bats instead relied on historical DNA—genomic data incidentally preserved in specimens that are housed in natural history collections—thus capitalizing on the research potential offered by a vast but hitherto relatively underutilized source of insight into the biological past.
Which choice best describes the function of the underlined portion in the text as a whole?
It specifies potential applications of the approach that Campana and colleagues used in their study.
A
It emphasizes the importance of Campana and colleagues’ findings about the DNA of pathogens.
B
It offers commentary on the significance of the approach that Campana and colleagues used for their study.
C
It explains why the research methodology selected by Campana and colleagues is not widely used.
D
