Did mammoths and elephants coexist?
The DNA revealed that woolly mammoths had more genetic similarities to modern Asian elephants than to the African species, though not by much, Hofreiter’s team reports. Modern elephants and woolly mammoths share a common ancestor that split into separate species about 6 million years ago, the study reports.
Are mammoths and elephants cousins?
Mammoths and elephants are close cousins belonging to the same taxonomic family, the Elephantidae. Elephantids, as they’re called, also belong to the broader biological group Proboscidea: an order of otherwise extinct beasts, such as mastodons and deinotheres.
Did woolly mammoths turn into elephants?
As members of the family Elephantidae, woolly mammoths were themselves elephants. Their last common ancestor with modern-day elephants lived somewhere in Africa about 6 million years ago.
