New genetic studies are helping scientists see when the extinct animals may have evolved some of their signature traits.
also located a gene with several mutations that may have been responsible for the woolly mammoth’s tiny ears.“We wanted to know what makes a mammoth a woolly mammoth,” said study co-author and paleogeneticist David Díez-del-Molino of the Centre for Palaeogenetics in Sweden.
An 18,000 year-old woolly mammoth tusk that was discovered in northeastern Siberia in 2015. Its genome was sequenced and is used in a new study.The team compared 23 Siberian woolly mammoth genomes with 28 modern-day Asian and African elephant genomes. Though woolly mammoths are hypothesized to have been on Earth, their genes had accrued a large number of mutations specifically during those 700,000 years in Siberia.
