An international team of researchers has sequenced the nearly complete genome of two Siberian woolly mammoths — revealing the most complete picture to date — including new information about the species’ evolutionary history and the conditions that led to its mass extinction at the end of the Ice Age.
“This discovery means that recreating extinct species is a much more real possibility, one we could in theory realize within decades,” says evolutionary geneticist Hendrik Poinar, director of the Ancient DNA Centre at McMaster University and a researcher at the Institute for Infectious Disease Research, the senior Canadian scientist on the project.
“With a complete genome and this kind of data, we can now begin to understand what made a mammoth a mammoth — when compared to an elephant — and some of the underlying causes of their extinction which is an exceptionally difficult and complex puzzle to solve,” he says.
While scientists have long argued that climate change and human hunting were major factors behind the mammoth’s extinction, the new data suggests multiple factors were at play over their long evolutionary history.
