Closing in on Sequencing the Neanderthal Genome

This news is from tomorrow’s New York Times:

Scientists in Germany Draft Neanderthal Genome

It’s about 63% complete at this point.  We live in magical times, scientifically.  Unbelievable.

Some nice tidbits from the article:

The Neanderthal genome, when fully analyzed, is expected to shed light on many critical aspects of human evolution. It will help document two important sets of genetic changes: those that occurred between 5.7 million years ago, when the human line split from the line leading to chimpanzees, and 300,000 years ago, when Neanderthals and the ancestors of modern humans parted ways; and second, the changes in the human line after it diverged from Neanderthals.

An early inference that can be drawn from the new findings, which were announced Thursday in Leipzig, Germany, is that there is no significant trace of Neanderthal genes in modern humans. This confounds the speculation that modern humans could have interbred with Neanderthals, thus benefiting from the genes that adapted the Neanderthals to the cold climate that prevailed in Europe in last ice age, which ended 10,000 years ago. Researchers have not ascertained if human genes entered the Neanderthal population.

Unfortunate for me – I had long been in the camp that speculated that Neanderthals weren’t actually a true species by the definition of inter-breeding.  I had expected that we’d discover some genetic evidence of interbreeding.

We’re in such early days of understanding our genome, it may be hard to appreciate how the advances in information science and genomics will profounding affect our understanding of species, both current & extinct.

I’m going to be on the lookout for more formal academic writings on this research.  A little surprised to see this come out today, instead of Tuesday, which is the official “Science Times” day…
