The culinary creations of Neanderthals might be a little basic for our modern tastes, but a new study suggests that they could cook up a warm stew – even if they didn’t have any pots or pans.
It has long been known that Neanderthals, who lived around 30,000 years ago, were skilled with fire – and now palaeontologists think they may have invented boil-in-the-bag cuisine.
Experts had thought that Homo sapiens were able to thrive, while Neanderthals died, thanks to their ability to heat up food, but new evidence suggests that Neanderthals boiled their food too.
Cooking makes certain nutrients and higher levels of fat available to a digestive system compared to some raw foods.
John Speth, an archaeologist at the University of Michigan, told a meeting at the Society for American Archaeology in Austen Texas: ‘I think it’s pretty likely the Neanderthals boiled’.
His belief is based upon ancient bones and spears National Geographic reported.
Professor Speth thinks that Neanderthals boiled their food in a bag made of skin - likely an animal’s paunch - or a bark tray, which would have worked because water will boil at a temperature slightly lower than the one needed to set the material holding it on fire.
‘You can boil in just about anything as long as you take it off the flame pretty quickly,’ he explained. Animal bones found at sites known to have been used by Neanderthals are 90 per cent free of gnawing marks, which suggests that fat had been heated and cooked off. A 2011 study also hints that Neanderthals might have heated grains. However, other academics are not so sure. Mary Stiner of the University of Arizona in Tucson, said she is ‘not convinced’ that they went as far as boiling food in bags or on bark.
Eskimos do something similar.
