Ancient genome reveals its secrets
Date:8/30/2012

This release is available in German.

The analyses of an international team of researchers led by Svante Pbo of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, show that the genetic variation of Denisovans was extremely low, suggesting that although they were present in large parts of Asia, their population was never large for long periods of time. In addition, a comprehensive list documents the genetic changes that set apart modern humans from their archaic relatives. Some of these changes concern genes that are associated with brain function or nervous system development.

In 2010 Svante Pbo and his colleagues sequenced DNA that they isolated from a finger bone fragment discovered in the Denisova Cave in southern Siberia. They found that it belonged to a young girl of a previously unknown group of archaic humans that they called "Denisovans". Thanks to a novel technique which splits the DNA double helix so that each of its two strands can be used for sequencing, the team was able to sequence every position in the Denisovan genome about 30 times over. The thus generated genome sequence shows a quality similar to genomes that have been determined from present-day humans.

In a new study, which is published in this week's issue of the journal Science, Svante Pbo and his colleagues compare the Denisovan genome with those of the Neandertals and eleven modern humans from around the world. Their findings confirm a previous study according to which modern populations from the islands of southeastern Asia share genes with the Denisovans. In addition, the genomes of people from East Asia, and South America include slightly more genes from Neandertals than those of people in Europe: "The excess archaic material in East Asia is more closely related to Neandertals than to Denisovans, so we estimate that the proportion of
