Fossils of ancient chromosomes found for the first time in 52,000-year-old woolly mammoth skin

A study has made a significant discovery by finding fossil chromosomes in a piece of woolly mammoth skin. The researchers found the 52,000-year-old remains in Siberia, and the freezing temperatures helped preserve the chromosomes in detail. Unlike previous DNA samples, which were fragmented, these chromosomes provide a more complete genetic picture. The structure of the chromosomes suggests a new method of preservation, offering potential for further research on extinct species. The researchers also hope to apply this methodology to samples from other species in museum collections, unlocking new insights into ancient genomes.
