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.
S napretkom u DNK tehnologiji, sada možemo započeti sekvencionirati genome drugih izumrlih vrsta mamuta koje sam spomenuo, a želim razgovarati samo o dvije vrste, vunenom i kolumbijskom mamutu, koji su živjeli vrlo blizu jedan drugome u vrijeme vrhunaca ledenih doba, i masivnih glečera u Sjevernoj Americi, te su tad vuneni potisnuti na subglacijalne ekosustave i došli su u kontakt sa svojim rođacima koji su živjeli na jugu, i tamo su dijelili refugij, a čini se i malo više od refugija.
