What do woolly mammoths eat




















What did giant mammals like woolly mammoths eat when they roamed the Arctic during the last ice age? A DNA analysis has solved that mystery and helps explain the rise and fall of giant mammals. Up until now, the diet of mammoths and other large herbivores that grazed in the Arctic 15, to 50, years ago has been a bit of a puzzle, according to Grant Zazula, a paleontologist with the Yukon government who co-authored the study published Wednesday online in the journal Nature.

That's because scientists had previously analyzed ancient pollen and concluded that there wasn't much vegetation in the Arctic during the ice age, just a small amount of grass. Meanwhile, paleontologists were uncovering the bones of ice age woolly rhinos, horses, and bison that would have needed generous amounts of food to keep their massive bodies fuelled up. Now, an international team led by Eske Willerslev, director of the Centre for Geogenetics at the Natural History Museum of Denmark, has come up with a vastly different picture of what the ice age Arctic looked like — and what kind of food was available.

By analyzing the DNA of plants preserved in the permafrost during the ice age, the team concluded that the Arctic landscape was not a bleak, grassy prairie at all, but had a lush cover of small, nutritious plants called forbs — "things like poppies and buttercups and anemones, little flowering plants," said Zazula.

Forbs include many plants that humans eat, including dandelion, sunflower, alfalfa, watercress, parsley and carrot. Because they eat plant material, mammoths are called herbivores.

Other types of animals have teeth adapted for eating meat. These animals are called carnivores. They have a set of very sharp molars that they use for tearing meat. Adult woolly mammoths could effectively defend themselves from predators with their tusks, trunks and size, but juveniles and weakened adults were vulnerable to pack hunters such as wolves, cave hyenas and large felines.

Woolly mammoths lived on flat tundra and grasslands south of the ice sheets or continental glaciers.

These areas were thought to have been covered in mosses, shrubs, and grasses. Russian scientists examined the preserved bones of a fully grown woolly mammoth that roamed the Earth about 10, years ago. The local inhabitants found its remains in a Siberian Lake in the north part of the country. The mammoth is any member of the extinct group of elephants found as fossils over every continent except South America and Australia and in some regions of North America.

They are members of the family Elephantidae. Therefore, woolly mammoths were elephants. Scientists believe that woolly mammoths evolved , years ago from the populations of steppe mammoths found in Siberia. DNA revealed that woolly mammoths had more similarities genetically to the modern Asian elephant than to the African species. Studies have reported that woolly mammoths and modern elephants share a common ancestor split into different species about six million years ago.

Mammoths were herbivores and fed mainly on grass and ate other types of flowers and plants such as dandelions or milkweed. Mammoths are believed to have needed to consume pounds of vegetation a day for survival.

Mammoths were not meat-eaters. Others feel that climate change was responsible. Hunting may have tipped the balance once the mammoth population had declined significantly. Other studies suggest that one of the last known groups of woolly mammoths died out due to a lack of drinking water.
