Ancient DNA refers to genetic material extracted from archaeological remains. It provides insights into the evolutionary history of species. Researchers analyse ancient DNA to understand migration patterns and population dynamics. This field enhances our knowledge of human ancestry and interactions with other species. It also sheds light on past climates and environments, contributing to our understanding of historical geography and ecology.
