Ancient human DNA from a 10000 years old "chewing gum"

In recent decades ancient DNA has been continuously used as a part of the tool-kit for studying human history and evolution. Ancient human DNA is found in both organic and inorganic material, for example, bones, teeth, mummified materials, coprolites, soil, etc. Bones and teeth harbor the... click to read more
