Genes solve the mystery of mammoth extinction: multiple genetic defects

Mammoth (Mamath primigenius), also known as a mammoth (long mammoth), is a ridged animal door, vertebrate sub-gate, lactation, real beast sub-gang, long nose, true long-nosed sub-eye, elephant, mammoth genus of an animal adapted to the cold climate. Once one of the world’s largest elephants, it is one of the largest mammals ever to survive on land, with prairie mammoths weighing up to 12 tons. It is a behemoth of the ice age.

Genes solve the mystery of mammoth extinction: multiple genetic defects

As one of the largest animals on land, mammoth extinction has been one of the issues scientists study, there is widespread speculation that climate change is the cause of extinction, human ancestors over-killing led to extinction is also deeply rooted.

But new research suggests that mammoth extinction may be due to its genes.

Recently, scientists “resurrected” the genes of mammoths found on the Siberian island and compared them with other Asian elephant genes to find that there are many problems with mammoth genes.

The study found that the island’s mammoths had a range of genetic defects, including problems with male fertility, neurodevelopment, insulin signals, and even the ability to smell flowers, and that the reason could be that the island’s mammoths were isolated from the mainland and had a smaller population (300-500). Inbreeding has deprived them of the opportunity to reproduce.

Of course, genetic problems do not explain why mammoths would go extinct altogether, but they offer more clues to current research and suggest that new technologies could solve more mysteries about prehistoric research.
