Last woolly mammoths offer clues to why they died out
UC geosciences professor discusses inbreeding in Earth's last mammoths
Science News Explores turned to a University of Cincinnati geosciences expert for context about a new study examining a genetic bottleneck in the world's last woolly mammoths.
Researchers from Stockholm University examined the genetics of remains from mammoths found on Russia's Wrangel Island, home to the last living population of the elephant-like leviathans of the Ice Age.
They found that the mammoths initially suffered from genetic mutations from inbreeding, but the population recovered within a few generations and remained stable. This suggests inbreeding may not have led to their extinction on the island.
UC College of Arts and Sciences Assistant Professor Joshua Miller told Science News Explores the study was remarkable. He was not part of the investigation but uses the latest scientific techniques to study mammoths and other prehistoric animals.
Miller said the study offers more clues to explain the demise of mammoths on Wrangel Island and offers promising insights into helping endangered species today using similar genetic tracking techniques.
Miller has trekked across the Arctic National Wildlife Refuge to study both historic and present migration patterns of caribou. And he uses tools such as isotopic analysis to answer questions about prehistoric animals.

The average time to clinical diagnosis of endometriosis is nine years. Definitive diagnosis of the disease is difficult, and until recently, has relied on laparoscopic surgery. Now, as Medscape recently reported, novel clinical recommendations, advanced diagnostic tools and research into inflammation and immune responses, are bringing promise that women with endometriosis will find relief sooner and without surgery, according to experts, including Katie Burns, PhD, University of Cincinnati College of Medicine associate professor.
