For palaeontologists, DNA is infuriatingly fragile. Its lengthy chains start to interrupt aside shortly after loss of life, destroying beneficial details about the deceased mum or dad organism. Not like bones, footprints and even faecal matter, which might comfortably survive—in fossilised kind—for thousands and thousands of years, DNA hardly ever lasts far more than 100. In current many years scientists have found that some exceptionally well-preserved our bodies do nonetheless have readable fragments of genetic code a whole lot of 1000’s of years after loss of life. However these have been tiny scraps. They lack a lot of the precious data that an intact genome supplies.
