The Department of Anthropology at Harvard University is pleased to share a new commentary by [Christina Warinner](/people/christina-warinner) and more published in *Nature*, titled "Ancient DNA data hold insights into past organisms and ecosystems — handle them with more care."

The article explores how DNA recovered from ancient remains is "transforming our understanding of organisms and ecosystems from tens, thousands and even millions of years ago," as well as the need to better preserve this growing amount of data.

> Most DNA sequence data are now archived in dedicated, publicly accessible databases, and the ancient DNA field has been heralded by some as a poster child for best practices in genetic data sharing[4](https://www.nature.com/articles/d41586-024-03993-z#ref-CR4),[5](https://www.nature.com/articles/d41586-024-03993-z#ref-CR5). However, as the pace of ancient DNA research has increased — largely thanks to the latest capabilities in DNA sequencing (see ‘A sampling surge’) — so, too, have problems with data archiving.
> 
> Often, only some of the data obtained in any one study are uploaded to publicly available databases. Furthermore, the associated metadata — information on the age of the sample, where it was found, how the DNA was extracted and chemically treated, and so on — are frequently inaccurate or incomplete.
