The scientists have recovered the oldest DNA on record from the teeth of siberian mammoths. highlights the DNA was extracted from the molars of mammoths. these mammoths were found in the north estern siberia some 1.2 million years ago.DNA was recovered and sequenced from the remains of three individual mamoths
elephant cousins that were among the large mammals that dominated Ice age landscapes entombed in permafrost conditions conducive to preeservation of ancient genetic material.
While the remains were discovered starting in the 1970s, new scientific methods were needed to extract the DNA.
The oldest of the three, discovered near the Krestovka river,was approximately 1,2 million years old.Another,from near the adycha river was approximately 1 to 1.2 million yeats old. the third, from near the chukochya river,was roughly 700,000 years old.
