With advances in ancient DNA technology, we can actually now start to begin to sequence the genomes of those other extinct mammoth forms that I mentioned, and I just wanted to talk about two of them, the woolly and the Columbian mammoth, both of which were living very close to each other during glacial peaks, so when the glaciers were massive in North America, the woollies were pushed into these subglacial ecotones, and came into contact with the relatives living to the south, and there they shared refugia, and a little bit more than the refugia, it turns out.
Com os avanços na tecnologia sobre DNA antigo, podemos realmente começar a sequenciar os genomas desses outros tipos de mamutes extintos que mencionei, e queria apenas falar de dois deles, o peludo e o 'Columbian', que estavam vivendo muito próximos um do outro durante os picos glaciais. Portanto, quando as geleiras eram maciças na América do Norte, os peludos eram empurrados para esses ecótonos subglaciais e entravam em contato com os parentes que viviam ao sul, e ali compartilhavam o refúgio, e um pouquinho mais que refúgio, na verdade.
