"Revolutionary: Woolly Rhino DNA Recovered from Hyena Scat"

Scientists have reconstructed the mitochondrial genome of a European Woolly Rhinoceros for the first time by extracting DNA from fossilized hyena feces, shedding light on the species' population dynamics and genetic distinctiveness from the Siberian population. The research, published in Biology Letters, suggests a split in populations dating back around 450,000 years ago and highlights the potential for further insights into extinct species and future wildlife populations through the study of ancient DNA.

Ancient Poop Unlocks Secrets of Extinct Wooly Rhinos

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.

Extracting ancient DNA from artifacts reveals human history.

Scientists have successfully extracted human DNA from a Paleolithic pendant, revealing that it belonged to a Siberian woman who lived around 25,000 years ago. The pendant was discovered in Denisova Cave in southern Siberia, which is known for its human occupation by Neanderthals, Denisovans, and modern humans. The new DNA extraction method used was nondestructive and involved submerging the artifact in a buffer bath of sodium phosphate. The researchers believe this method could be used on other ancient artifacts, but caution that proper equipment must be worn to avoid cross-contamination.
