Colossal Biosciences has focused on identifying key traits of extinct animals by studying ancient DNA, with a goal to genetically "engineer them into living animals," said CEO Ben Lamm.

The researchers' analysis suggests that this type of splicing arose in a common ancestor of plants, animals, and fungi, but it was lost from fungi soon after they diverged from plants and animals.

Experiments on mice could see hairy, genetically modified elephants living in the Arctic, a US company claims.
