Ancient Dna

Ancient DNA is any type of DNA found in ancient, long-dead organisms. This type of DNA may be preserved even in non-fossilized remains for thousands of years, and can sometimes give us insight into the origins, evolutionary histories, and migrations of organisms and populations. Ancient DNA can also be studied to answer questions about human health, societal relationships, and loss of species. Ancient DNA can help us to better understand the relationships between our ancestors and the world around them, and to see how they responded to changing environments and climate over the centuries. It has also been used in criminal investigations, to study infectious disease, and to explore long-term climate change.
