Genome recovered from environmental sediments

Context:

Body remains such as skeletons have been widely known to hold crucial information in archeology as they can store neuclear DNA or mitochondrial DNA. Soil sediments too, can store DNA from as early as Paleolithic Age. These sediments are known to hold environmental DNA as well as neuclear DNA. Sediment DNA recovered from various caves, play an important role in tracking the presence of many species. Here we're going to talk about such a study on environmental DNA recovered from a sediment layer.

Let's Deep Dive:


what has been found:

A sediment cluster was examined and sampled. It was a clay based sediment, found in the Satsurblia Cave which is situated at the Southern part of Caucasus Mts. in Georgia. The cave is known as an archeological site of Late Upper Paleolithic Age.

A team of researchers has conducted the study, the team consists of Pere Gelabert, Susanna Sawyer, Anders Bergström, Ashot Margaryan, Thomas C.
