Genomic analysis details eastern gorilla's declining genetic health

Science
Dec. 27 (UPI) -- New analysis of the critically endangered Grauer's gorilla's genome suggests the species' health is suffering from a loss of genetic diversity. Scientists sequenced the genomes of several eastern gorilla specimens collected a century ago and compared the results to the genomes of modern Grauer's gorillas. The results, published Thursday in the journal Current Biology, showed Grauer's gorillas have accumulated harmful mutations as they have lost genetic diversity. "We found that the genetic diversity in Grauer's gorilla has declined significantly in just a few generations," Tom van der Valk, a doctoral student at Uppsala University in Sweden, said in a news release. Over the last several decades, poaching and habitat losses in the Democratic Republic of the Congo have led ...
