Experts Studying The 14,000-Year-Old Remains Of A Frozen Siberian Puppy Made A Genetic Breakthrough

Scientists are poring over the body of a puppy; but this is no ordinary animal. The young pup has lain frozen in the Siberian permafrost for 14,300 years. Painstakingly, the researchers extract samples of tissue from cartilage, liver and muscle. And once they’ve analyzed the samples in the lab they make a groundbreaking discovery – and it may have huge implications for science.
