He's probably the most famous frozen corpse in the world - and now we're one step closer to knowing more about the 5,300-year-old Ötzi iceman.

Ötzi the iceman's full genome has been published in the science journal nature communications, revealing his eye colour and that he was lactose intolerant.

The iceman's mummified body was discovered in 1991 in the Italian Alps, and scientists have been finding out as much as they can about him ever since. One theory is that he was stabbed in the back - and died after fighting his attacker.

Now researchers, led by Professor Albert Zink, of the EURAC-Institute for Mummies and the Iceman, have revealed he had brown eyes and an increased risk of heart disease.

According to previous research he was 5'5 and about 45 years old when he died.
