The extinct beasts had a form of antifreeze blood that kept their bodies supplied with oxygen in the sub-zero temperatures, according to a study of DNA extracted from 43,000-year-old mammoth remains.
A genetic adaptation in the woolly mammoths' haemoglobin – the molecular cage that carries oxygen in the blood – allowed them to thrive at high latitudes without losing much heat.
