Really excited to see this published! Some of the ancient bear work came out of my PhD studies many years ago, and @alexander_salis @KierenJMitchell + a large team have continued + expanded it in a way I couldn’t have to deliver this impressive story today!https://t.co/pSesIx4Nij

How cool are ice age bears and lions? My coauthors @alexander_salis @KierenJMitchell @DeepFriedDNA @michael_s_y_lee et al and I used ancient DNA to reveal multiple synchronous waves of dispersal in both brown bears and lions across the Bering Land Bridge. https://t.co/4GZm9NKWTP

Super excited not only to see this research on ancient DNA from bears and lions published at last, but also as a cover story with my brother's Alaskan brown bear photo on the front of @molecol!

The Bering Land Bridge was the mode of transportation for hundreds of species to inhabit North America. This article discusses how glacial periods that opened and closed the land bridge affected lion and bear genomes and their turnover rates #MUevolution22 https://t.co/38bHPds8qU

It's true! Mammoths had a section of their trunk that worked as a trunk cosy in case the sensitive tip of their trunks got a bit chilly. Knowing baby mammoth Lyuba had a cosy trunk makes me inordinately happy! How warm is your snout?
