Researchers mapped the mammoth family tree by extracting DNA from fossils. Also, scientists found some sessile animals living under Antarctica's ice shelf, and they're really cool.

      Lo interesante son los lobos gigantes prehistóricos, leones gigantes prehistóricos de América, junto el águila de hast, si pudiera estudiarse sus cuerpos y como funcionan, así como que tipo de mitocondrias, células madre, membranas celulares y otras cosas tenían, antes de expirar el adn pues tiene períodos de vida y conservación de 12 000 años o 10 000 años, quizás en frío, congelado y en algo como miel de abeja reina, 14 000 años, sugerencia.

    At 2:35, I don't understand. If Unknown Mammoth #2 interbred with Woolly Mammoth to create Columbian Mammoth, then there would be Unknown Mammoth #2 and Woolly Mammoth DNA in Columbian Mammoths. But that's not what Hank said. He said "That other separate group was a partial match for Columbian Mammoths and a partial match for Woolly Mammoths." That makes it sound like Unknown Mammoth #2 was the product of Woolly Mammoth and Columbian Mammoth interbreeding, not the other way around. A mule has DNA from a horse and donkey. A horse and donkey don't acquire common DNA because they produce a mule. You've got genes flowing backwards along the tree of life. What am I missing?

    I think they are going to be able to sequence Some later Homo Erectus DNA. Recently, they used teeth protein to sequence Homo Antecessor from Spain (Dated 800k years ago) and found that Homo Antecessor is a close Sister Lineage to the one that Homo Sapiens, Neanderthals and Denisovans split from. My guess is if they sequence Erectus they are going to find lots of DNA that was found in the Modern Human Genome, Neanderthal Genome and Denisovan Genome that goes back to Erectus. In fact, there is already some evidence for that already with respect to Skin pigment alleles, both lighter and darker, dating back > 1 million years. See Crawford et al 2017 " Loci associated with skin pigmentation identified in African populations".
