Neandertal genome in one week's time?

Wed, 2009-02-04 15:02 -- John Hawks

Rex Dalton reports that Svante Pääbo's presentation at the AAAS meetings next week will have a little surprise:

Project leader Svante Pääbo will announce the results of the preliminary genomic analysis at the American Association for the Advancement of Science annual meeting in Chicago, Illinois, which starts on 12 February.

"We are working like crazy at the moment," says Pääbo, adding that his Max Planck colleague, computational biologist Richard Green, is coordinating the analysis of the genome's 3 billion base pairs.

...

Pääbo says that his group will publish a first draft of the entire Neanderthal genome later this year, as a single read of all base pairs. However, some published human genomes had all their base pairs read eight to ten times before publication. The team says that its single-read of the Neanderthal genome is sufficient for publication because the technique used does not rely on the same DNA reassembly process used in conventional 'shotgun' sequencing.

Three billion base pairs. Perhaps 4000 amino acid substitutions between them and us, and an unknown number of regulatory changes. There are likely to be some surprising similarities, as well as many surprising differences.

We're going to have plenty of work.

Anyway, the story doesn't specify what will be new about next week's announcement. I'm sure there will be some surprises.

Neandertals

For years, I've worked on their bones. Now I'm working on their genes. Read more about the science studying these ancient people.

Denisova

From a finger bone of an ancient human came the record of a completely unexpected population. My lab is working on the science of the Denisova genome.

Acceleration

The advent of agriculture caused natural selection to speed up greatly in humans. We're uncovering some of the ways that populations have rapidly changed during the last 10,000 years.

Malapa

Just outside Johannesburg, the Malapa site is producing some of the most exciting finds in human evolution. This site is the headquarters of the Malapa Soft Tissue Project.
