Scientists have successfully created a 3D reconstruction of 52,000-year-old chromosomes from freeze-dried woolly mammoth skin found in Siberia, revealing active genes in the skin cells when the mammoth was alive. This groundbreaking achievement in ancient DNA research could aid efforts to de-extinct the mammoth by integrating its genes into modern elephants.
Scientists have successfully reconstructed the mitochondrial genome of the extinct wooly rhinoceros using DNA extracted from fossilized feces of cave hyenas. The study contradicts previous theories about the wooly rhino's range expansion and provides important insights into regional differences among woolly rhino populations. The genetic material was obtained from a single coprolite sample, highlighting the value of ancient DNA analysis. This discovery offers a better understanding of the wooly rhinos that once roamed the Earth and their historical past.
