Evolution
The earliest known proboscideans, the clade that contains the elephants, existed about 55 million years ago around the Tethys Sea area. The closest relatives of the Proboscidea are the sirenians and the hyraxes. The family Elephantidae is known to have existed six million years ago in Africa, and includes the living elephants and the mammoths. Among many now extinct clades, the mastodon is only a distant relative of the mammoths, and part of the separate Mammutidae family, which diverged 25 million years before the mammoths evolved.

shows the placement of the genus ''Mammuthus'' among other proboscideans, based on hyoid characteristics:
Since many remains of each species of mammoth are known from several localities, it is possible to reconstruct the evolutionary history of the genus through morphological studies. Mammoth species can be identified from the number of enamel ridges on their molars; the primitive species had few ridges, and the amount increased gradually as new species evolved and replaced the former ones. At the same time, the crowns of the teeth became longer, and the skulls become higher from top to bottom and shorter from the back to the front over time to accommodate this.
The first known members of the genus ''Mammuthus'' are the African species '' Mammuthus subplanifrons'' from the

. The former is thought to be the ancestor of later forms. Mammoths entered Europe around 3 million years ago; the earliest known type has been named ''M. rumanus'', which spread across Europe and China. Only its molars are known, which show it had 8–10 enamel ridges. A population evolved 12–14 ridges and split off from and replaced the earlier type, becoming '' M. meridionalis''. In turn, this species was replaced by the steppe mammoth, ''

The woolly mammoth (''Mammuthus primigenius'') is an extinct species of mammoth that lived during the Pleistocene until its extinction in the Holocene epoch. It was one of the last in a line of mammoth species, beginning with '' Mammuthus sub ...
, ''M. primigenius''. The woolly mammoth would replace the steppe mammoth in Europe during the late Middle Pleistocene around 200,000 years ago. A 2011 genetic study showed that two examined specimens of the Columbian mammoth were grouped within a subclade of woolly mammoths. This suggests that the two populations interbred and produced fertile offspring. It also suggested that a North American form known as "''M. jeffersonii''" may be a hybrid between the two species.
By the late Pleistocene, mammoths in continental Eurasia had undergone a major transformation, including a shortening and heightening of the cranium and mandible, increase in molar hypsodonty index, increase in plate number, and thinning of dental enamel. Due to this change in physical appearance, it became customary to group European mammoths separately into distinguishable clusters:
# Early Pleistocene – ''Mammuthus meridionalis''
# Middle Pleistocene – ''Mammuthus trogontherii''
# Late Pleistocene – ''Mammuthus primigenius''
There is speculation as to what caused this variation within the three chronospecies. Variations in environment, climate change, and migration surely played roles in the evolutionary process of the mammoths. Take ''M. primigenius'' for example: Woolly mammoths lived in opened grassland biomes. The cool steppe-tundra of the Northern Hemisphere was the ideal place for mammoths to thrive because of the resources it supplied. With occasional warmings during the ice age, climate would change the landscape, and resources available to the mammoths altered accordingly.
In February 2021, scientists reported that DNA from million-year old mammoth remains had become the oldest ever sequenced.
Etymology and early observations
The word ''mammoth'' was first used in Europe during the early 17th century, when referring to ''maimanto'' tusks discovered in Siberia. John Bell, who was on the Ob River in 1722, said that mammoth tusks were well known in the area. They were called "mammon's horn" and were often found in washed-out river banks. Some local people claimed to have seen a living mammoth, but they came out only at night and always disappeared under water when detected. He bought one and presented it to

of the Irtysh River basin, a belief existed that the mammoth was some kind of a water spirit. According to other Khanty, the mammoth was a creature that lived underground, burrowing its tunnels as it went, and would die if it accidentally came to the surface.
The concept of the mammoth as an underground creature was known to the Chinese, who received some mammoth ivory from the Siberian natives; accordingly, the creature was known in China as ''yǐn shǔ'' 隐鼠, "the hidden rodent".

Like their modern relatives, mammoths were quite large. The largest known species reached heights in the region of at the shoulder and weights of up to , while exceptionally large males may have exceeded . However, most species of mammoth were only about as large as a modern

(which are about 2.5 m to 3 m high at the shoulder, and rarely exceeding 5 tonnes). Both sexes bore tusks. A first, small set appeared at about the age of six months, and these were replaced at about 18 months by the permanent set. Growth of the permanent set was at a rate of about per year.
Based on studies of their close relatives, the modern elephants, mammoths probably had a

period of 22 months, resulting in a single calf being born. Their social structure was probably the same as that of African and Asian elephants, with females living in herds headed by a matriarch, whilst bulls lived solitary lives or formed loose groups after sexual maturity.
Scientists discovered and studied the remains of a mammoth calf, and found that fat greatly influenced its form, and enabled it to store large amounts of nutrients necessary for survival in temperatures as low as . The fat also allowed the mammoths to increase their muscle mass, allowing the mammoths to fight against enemies and live longer. Woolly mammoths evolved a suite of adaptations for arctic life, including morphological traits such as small ears and tails to minimize heat loss, a thick layer of subcutaneous fat, long thick fur, and numerous sebaceous glands for insulation , as well as a large brown-fat hump like deposit behind the neck that may have functioned as a heat source and fat reservoir during winter.
Diet
Depending on the species or race of mammoth, the diet differed somewhat depending on location, although all mammoths ate similar things. For the Columbian mammoth, '' M. columbi'', the diet was mainly

. American Columbian mammoths fed primarily on cactus leaves, trees, and shrubs. These assumptions were based on mammoth feces and mammoth teeth. Mammoths, like modern day elephants, have hypsodont molars. These features also allowed mammoths to live an expansive life because of the availability of grasses and trees.
For the Mongochen mammoth, its diet consisted of herbs, grasses, larch, and shrubs, and possibly
alder
Alders are trees comprising the genus ''Alnus'' in the birch family Betulaceae. The genus comprises about 35 species of monoecious trees and shrubs, a few reaching a large size, distributed throughout the north temperate zone with a few sp ...
. These inferences were made through the observation of mammoth feces, which scientists observed contained non-arboreal pollen and moss spores.
European mammoths had a major diet of C3 carbon fixation plants. This was determined by examining the isotopic data from the European mammoth teeth.
The arctic tundra and steppe where the mammoths lived appears to have been dominated by forbs, not grass. These were richer in protein and easier to digest than grasses and wooden plants, which came to dominate the areas when the climate became wetter and warmer. This could have been a major contributor to why the arctic megafauna went extinct.
The Yamal baby mammoth Lyuba, found in 2007 in the Yamal Peninsula in Western Siberia, suggests that baby mammoths, as do modern baby elephants, ate the dung of adult animals. The evidence to show this is that the dentition (teeth) of the baby mammoth had not yet fully developed to chew grass. Furthermore, there was an abundance of ascospores of coprophilous fungi from the pollen spectrum of the baby's mother. Coprophilous fungi are fungi that grow on animal dung and disperse spores in nearby vegetation, which the baby mammoth would then consume. Spores might have gotten into its stomach while grazing for the first few times. Coprophagy may be an adaptation, serving to populate the infant's gut with the needed

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 similarwarming episodes had occurred previously within the

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.

, was roughly concurrent with the Wrangel population. The close relationship between decreasing mammoth populations and steppe, as well as the lack of a sudden decline that would be associated with the human overkill hypothesis, indicates that humans and mammoths may have coexisted for millennia, and thus humans may have only played a minor role in the species' extinction.
Many hypotheses also seek to explain the regional extinction of mammoths in specific areas. Scientists have speculated that the mammoths of Saint Paul Island (Alaska), an isolated enclave where mammoths survived until about 8,000 years ago, died out as the island shrank by 80–90% when sea levels rose, eventually making it too small to support a viable population. Similarly, genome sequences of the Wrangel Island mammoths indicate a sharp decline in genetic diversity, though the extent to which this played a role in their extinction is still unclear. Another hypothesis, said to be the cause of mammoth extinction in Siberia, comes from the idea that many may have drowned. While traveling to the Northern River, many of these mammoths broke through the ice and drowned. This also explains bones remains in the Arctic Coast and some of the New Siberian Islands.
