The
famous Columbian mammoth — an 11-ton creature known for traversing North
America during the last ice age — might actually be the same species as the
Eurasian steppe mammoth, a new study finds.
The
discovery suggests that the first mammoth to enter North America was the
Eurasian steppe mammoth, and not its ancestor, a European creature
called Mammuthus meridionalis. The two species differed greatly — the
steppe mammoth had many more adaptations to living in cold weather.
The
finding helps to rewrite the story of the evolution of the mammoth in North
America, said study co-researcher Adrian Lister, a research
leader of
paleontology at the Natural History Museum in London.
