Scientists find woolly mammoth DNA while digging through squirrel faeces
Scientists discovered ancient DNA from woolly mammoths and other animals in frozen squirrel faeces in Canada's Yukon territory. The DNA, aged 3,000 to 700,000 years, was found in sealed-off burrows and includes genetic material from wolves. The US company Colossal aims to 'de-extinct' woolly mammoths.
