What is genetic dating anthropology?
This method compares the amount of genetic difference between living organisms and computes an age based on well-tested rates of genetic mutation over time. Since genetic material (like DNA) decays rapidly, the molecular clock method cant date very old fossils.
What is the oldest DNA ever found?
Scientists say they have discovered the oldest DNA on record. It was found in the teeth of mammoths that lived in northeastern Siberia up to 1.2 million years ago. A mammoth was a kind of early elephant that lived during the Ice Age.
