Scientists led by Dr Svante Paabo from the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany used a toe bone excavated in 2010 in Denisova Cave in southern Siberia to generate a high-quality genome from a single Neanderthal individual.
In 2010, Paabo and colleagues had presented the first draft version of the Neanderthal genome from data collected from three bones found in a cave in Croatia. In this draft version of the Neanderthal genome, each position was determined, on average, once.
"The genome is of very high quality. It matches the quality of the Denisovan genome, presented last year, and is as good as or even better than the multiple present-day human genomes available to date," study researcher Kay Prufer said in a statement.
The analysis of the genome along with other research shows that the Neanderthal individual is closely related to other Neanderthals in Europe and western Russia.
"We will gain insights into many aspects of the history of both Neanderthals and Denisovans and refine our knowledge about the genetic changes that occurred in the genomes of modern humans after they parted ways with the ancestors of Neanderthals and Denisovans," he said.
The group will present a paper describing the genome later this year but the genome sequence is now available online for free to other scientists.
