In 2004, a method of extracting DNA from within tusks and horns of elephants and rhinos was produced. Now, ten years later, this method is being used by scientists in Asia. DNA is being extracted from ivory confiscated from illegal sources, and is being used to track back the range of the animal from which it originated. This method is proving to be key in identifying the poaching ‘hot spots’ of elephants and rhinos in Africa.
