The evolution of mammoths

The earliest known mammoth is the Pliocene African mammoth, which lived in tropical Africa and entered the Pleistocene. Mammoths left Africa and went to Eurasia and North America. The earliest known mammoth in Asia and Europe was the Romanian mammoth in the early Pleistocene. In the Middle Pleistocene, the mammoth population became more and more diverse, and the true mammoth in the colder regions of Eurasia and the imperial mammoth in the warmer regions of North America were both representative groups. In the late Pleistocene, the real mammoth entered North America, replacing the larger imperial mammoth. Later, the largest mammoth species in North America (similar to the imperial mammoth, without long hair) evolved. The largest mammoth population may be the grassland mammoth mainly produced in Eurasia, which evolved from the southern mammoth in the warm area of Eurasia. The most famous woolly mammoth group is smaller than the above group.

Mammoths are more fierce than elephants nowadays.

In fact, in the middle and late Cenozoic era, the long-nosed order developed into a world-wide and once prominent family mainly along two evolutionary routes. One of them is the main line of evolution, an elephant evolved from an ancient mastodon, and the other is a small branch that evolved into phobia, but it became extinct in the middle and late Pleistocene.

Since ancient times, many kinds of elephants have been differentiated. Archaeopteryx, about the size of an underage Asian elephant, has a tapir-like nose and no ivory. It is an evolutionary branch of the long nose order. It was completely extinct in the early Oligocene, and it was not the direct ancestor of elephants, nor even represented the early proboscis. Archaeopteryx's lifestyle has deviated from the mainstream of the long nose order, but it is indeed the most famous one of the early long nose orders. Later, mastodons, shovels and phobias gradually appeared, and by the Miocene, they had developed very prosperously and had a wide variety. The wheel of history suddenly turned to the Quaternary, before which elephants quickly disappeared, and at the same time, new kinds of elephants appeared. Saber-toothed elephant, ancient toothed elephant and mammoth are typical representatives of elephant family. Elephants were divided into three mountains before entering modern times. Saber-toothed elephants occupied the southern and tropical regions. The ancient ling image occupied the subtropical region in the central region, and then went north to the snowy region. Its overlord was mammoth! Mammoths are related to elephants today. However, it is much more fierce than today's elephants! Adult mammoths are huge, and other animals pose no threat to them on the plains. Scientists claim that although female mammoths may be gentle in peacetime, they are extremely violent when raising their young. At this time, mammoths will suddenly attack any seemingly "threatening" animal, and their opponents will often be run over before they are "awake". Male mammoths, like male African elephants today, live alone and have a worse temper. There is no doubt that mammoths are at the top of the whole food chain. However, it takes 15 years for young mammoths to develop and shape. Therefore, fierce predators can easily harm these young elephants, especially the small group of saber-toothed tigers. Although the saber-toothed tiger was only a medium-sized saber-toothed tiger, it was the carnivore who liked to attack mammoths most at that time. A large number of mammoths drowned in mud flats were found in asphalt pits in the United States, which attracted blade-toothed tigers and wolf-fearing fossils and eventually died here. Because they will eat dead mammoths, they are likely to attack mammoth cubs. Old and frail mammoths may also be attacked by giant carnivores such as giant short-faced bears or cave bears. There are other large herbivores who once lived with mammoths, and mammoths dare not provoke them easily. For example, the American mastodon, which is also covered with long hair, and the largest horned rhinoceros, the platon rhinoceros, are not smaller than the woolly mammoth, and they may become the survival competitors of the mammoth.
