Using Genomics To Trace Ice Planet History: Octopus DNA Reveals West Antarctic Ice Sheet Collapse During Last Interglacial

Genetic analyses of an Antarctic octopus show that the West Antarctic Ice Sheet (WAIS) collapsed during the Last Interglacial ~129,000 to 116,000 years ago when temperatures were only about 1 […]
