mammoth : any of a genus (Mammuthus) of extinct Pleistocene mammals of the elephant family distinguished from recent elephants by highly ridged molars, usually large size, very long tusks that curve upward, and well-developed body hair — Webster
Mammoth is any species of the extinct genus Mammuthus, one of the many genera that make up the order of trunked mammals called proboscideans. The various species of mammoth were commonly equipped with long, curved tusks and, in northern species, a covering of long hair. They lived from the Pliocene epoch (from around 5 million years ago) into the Holocene at about 4,000 years ago, and various species existed in Africa, Europe, Asia, and North America. They were members of the family Elephantidae, which also contains the two genera of modern elephants and their ancestors.
The oldest representative of Mammuthus, the South African mammoth (M. subplanifrons), appeared around 5 million years ago during the early Pliocene in what is now southern and eastern Africa. Descendant species of these mammoths moved north and continued to propagate into numerous subsequent species, eventually covering most of Eurasia before extending into the Americas at least 600,000 years ago. The last species to emerge, the woolly mammoth (M. primigenius), developed about 400,000 years ago in East Asia, with some surviving on Russia’s Wrangel Island in the Arctic Ocean until as recently as roughly 3,700 to 4,000 years ago, still in existence during the construction of the Great Pyramid of ancient Egypt. — Wikipedia

Naturalists Alfred Russel Wallace and Charles Darwin both presented the theory of evolution at the same time in 1858. They thus changed both the course of biology and how we understand the natural world around us.

A new study shows that 87 genes have been affected by deletions or short insertions during the course of the mammoth's evolution. The researchers note that their findings have implications for international efforts to resurrect extinct species, including the woolly mammoth. The study was published today in the journal iScience by researchers at the Centre for Palaeogenetics in Stockholm, a collaboration between Stockholm University and the Swedish Museum of Natural History.
- CT scanner captures entire wooly mammoth tuskon August 9, 2022 at 6:33 pm
For the first time, researchers successfully captured CT images of an entire wooly mammoth tusk, according to a new "Images in Radiology" article published in the journal Radiology. Researchers were able to do a full scan of the tusk in its entirety—or in toto—using a newer clinical CT scanner. The new technology allows for large-scale imaging without having to do multiple partial scans.

Mineral-rich waters originating from the Apennine Mountains of Italy flowed through ancient Rome's Anio Novus aqueduct and left behind a detailed rock record of past hydraulic conditions, researchers have said. Two studies characterizing layered limestone—called travertine—deposits within the Anio Novus are the first to document the occurrence of anti-gravity growth ripples and establish that these features lend clues to the history of ancient water conveyance and storage systems.
