International Scientists team have recovered the oldest DNA (Deoxyribonucleic acid) on record from the teeth of Siberian Mammoths.

Points To Note

  • Deoxyribonucleic acid was extracted from the molars of mammoths.
  • These mammoths were found in the north-eastern Siberia some 1.2 million years ago.
  • Deoxyribonucleic acid was recovered and sequenced from the remains of three individual mammoths.
  • The mammoths were among the large mammals who dominated Ice Age landscapes.


The remains of the mammoths were discovered in the early 1970s. However, since then, new scientific methods were required to extract the Deoxyribonucleic acid.


  • The oldest of the 3 mammoths was discovered near Krestovka river.
  • Scientists study reveal that, this mammoth was 1.2 million years old.
  • Another mammoth was discovered near the Adycha river and is 1 to 1.2 million years old.
  • While, the 3rd mammoth was recovered from Chukochya river (Russia). It is around 7 lakh years old.


The Mammoth is the species of extinct elephantid of genus Mammuthus. It was equipped with the long, curved tusks and a covering of long hair. They were found from the Pliocene epoch to the Holocene some four thousand years ago. The species existed in the Europe, North America, Africa and Asia. They belonged to the family Elephantidae. The Elephantidae family also comprises of two genera of modern elephants and their ancestors.

DNA (Deoxyribonucleic acid)

DNA is a composed of two polynucleotide chains. These polynucleotide chains are coil around each other and form the double helix. The helix carries the genetic instructions for the growth, development, functioning, and reproduction of organisms and viruses. It is a self-replicating material carrying the genetic information of the living organisms.
