Scientists have discovered ancient fossil chromosomes preserved in a glass-like state in the skin of a 52,000-year-old female woolly mammoth that died near the Indigirka River in Siberia .
Chromosomes are threadlike structures composed entirely of DNA that reside in the cells of all living things.
The half -life of DNA is 521 years , making the preservation of long sequences extremely rare.
Moving forward, scientists hope that similar fossil chromosomes could be discovered in other specimens. “Ancient Egyptian priests believed that mummification prepared a person or animal to be reanimated in a future life,” the scientists wrote in their study published in the journal Cell . “They may have been closer to the mark than has been realized.” Thanks for your feedback!
