cientists have sequenced what is thought to be the world’s oldest DNA samples, taken from the ancient steppe mammoth, revealing new information about how later species of mammoth evolved and adapted to different climates.

An international team led by researchers at the Centre for Palaeogenetics in Stockholm sequenced DNA recovered from mammoth remains up to 1.2 million years old.

The analyses found the Columbian mammoth species, which inhabited North America during the last ice age, was a hybrid between the woolly mammoth and a previously unknown genetic lineage of mammoth.
