Shanlin Liu and colleagues relied on historical DNA (hDNA)—genomic data incidentally preserved in specimens housed in natural history collections—to investigate the evolutionary history of the rhinoceros family (Rhinocerotidae). Although this approach offers unique benefits, such as the ability to ascertain the biogeographical origins of organisms, it remains a relatively underutilized resource because hDNA is often to some extent degraded, a situation not easily remediable under current methodological paradigms and with extant DNA extraction and analysis technologies.
Information in the text best supports which statement about hDNA?
It may be underused because of its controversial status among scientists.
A
It tends to be much more degraded than other types of DNA of comparable age.
B
It may yield insights that other types of genomic data cannot.
C
It has thus far proved valuable mainly to researchers studying mammals.
D
