NEW YORK (GenomeWeb) – An analysis of available ancient genome sequences suggests that the genome of the woolly mammoth, Mammuthus primigenius, began taking on ever more potentially deleterious mutations as populations dwindled and the species got closer to extinction — a finding that may have implications for recognizing species at risk and implementing appropriate conservation measures.
"There is a long history of theoretical work about how genomes might change in small populations," Rebekah Rogers, an integrative biology researcher at the University of California, Berkeley, said in a statement. "Here, we got a rare chance to look at snapshots of genomes 'before' and 'after' a population decline in a single species."/.../
