The woolly mammoth (M. primigenius) was the last species of the genus.
Most populations of the woolly mammoth in North America and Eurasia, as well as all the Columbian mammoths (M. columbi) in North America, died out around the time of the last glacial retreat, as part of a mass extinction of megafauna in northern Eurasia and the Americas.
Until recently, the last woolly mammoths were generally assumed to have vanished from Europe and southern Siberia about 12,000 years ago, but new findings show some were still present there about 10,000 years ago.
Slightly later, the woolly mammoths also disappeared from continental northern Siberia.
A small population survived on St. Paul Island, Alaska, up until 3750 BC, and the small mammoths of Wrangel Island survived until 1650 BC.
Recent research of sediments in Alaska indicates mammoths survived on the American mainland until 10,000 years ago.

A definitive explanation for their extinction has yet to be agreed upon.
The warming trend (Holocene) that occurred 12,000 years ago, accompanied by a glacial retreat and rising sea levels, has been suggested as a contributing factor.
Forests replaced open woodlands and grasslands across the continent.
The available habitat would have been reduced for some megafaunal species, such as the mammoth.
However, such climate changes were nothing new; numerous very similar warming episodes had occurred previously within the ice age of the last several million years without producing comparable megafaunal extinctions, so climate alone is unlikely to have played a decisive role.
The spread of advanced human hunters through northern Eurasia and the Americas around the time of the extinctions, however, was a new development, and thus might have contributed significantly.

Whether the general mammoth population died out for climatic reasons or due to overhunting by humans is controversial.
During the transition from the Late Pleistocene epoch to the Holocene epoch, there was shrinkage of the distribution of the mammoth because progressive warming at the end of the Pleistocene epoch changed the mammoth's environment.
The mammoth steppe was a periglacial landscape with rich herb and grass vegetation that disappeared along with the mammoth because of environmental changes in the climate.
Mammoths had moved to isolated spots in Eurasia, where they disappeared completely.
Also, it is thought that Late Paleolithic and Mesolithic human hunters might have affected the size of the last mammoth populations in Europe.
There is evidence to suggest that humans did cause the mammoth extinction, although there is no definitive proof.
It was found that humans living south of a mammoth steppe learned to adapt themselves to the harsher climates north of the steppe, where mammoths resided.
It was concluded that if humans could survive the harsh north climate of that particular mammoth steppe then it was possible humans could hunt (and eventually extinguish) mammoths everywhere.
Another hypothesis suggests mammoths fell victim to an infectious disease.

A combination of climate change and hunting by humans may be a possible explanation for their extinction.
Homo erectus is known to have consumed mammoth meat as early as 1.8 million years ago, though this may mean only successful scavenging, rather than actual hunting.
Later humans show greater evidence for hunting mammoths; mammoth bones at a 50,000-year-old site in South Britain suggest that Neanderthals butchered the animals, while various sites in Eastern Europe dating from 15,000 to 44,000 years old suggest humans (probably Homo sapiens) built dwellings using mammoth bones (the age of some of the earlier structures suggests that Neanderthals began the practice).
However, the American Institute of Biological Sciences notes that bones of dead elephants, left on the ground and subsequently trampled by other elephants, tend to bear marks resembling butchery marks, which have allegedly been misinterpreted as such by archaeologists.

Many hypotheses also seek to explain the regional extinction of mammoths in specific areas.
