52,000-year-old mammoth meat declared a scientific game-changer

The discovery of 52,000-year-old fossil chromosomes preserved in a glass-like state inside the skin of a woolly mammoth is a groundbreaking find. This sample, which retains the three-dimensional arrangement of DNA fragments, offers a million times more genetic sequence data than previously found ancient DNA fragments. Scientists have reconstructed the entire genomic architecture of the mammoth, bringing researchers closer to the potential de-extinction of this colossal mammal. The mammoth's skin, found in Northern Siberia, preserved its chromosomes due to a process akin to spontaneous freeze-drying, resembling the method used to produce beef jerky. The research team utilized this discovery to identify several active genes that were not present in the mammoth’s modern-day relatives, such as the Asian elephant. This revelation offers tremendous insight into the history and evolution of the mammoth and may greatly aid current de-extinction efforts.

The preservation of ancient DNA in a glass-like state allows scientists to access an unprecedented wealth of genetic information, enabling the reconstruction of entire genomic sequences of extinct creatures. This can lead to significant breakthroughs in understanding the history and evolution of these animals and potentially assist in efforts to bring them back from extinction.

Woolly mammoths roamed the Earth during the last Ice Age, around 400,000 years ago until their extinction around 4,000 years ago. Recent scientific endeavors, supported by companies like Colossal Biosciences, are exploring ways to resurrect the species using advanced genomic technologies. These efforts include projects to integrate woolly mammoth DNA into the genome of their closest living relatives, the Asian elephants, to potentially recreate the species and introduce them back into modern ecosystems.
