Quite an interesting article on Neanderthal genome studies...

Scientists create genetic blueprint of Neanderthal

"An international team Thursday said it has completed a draft of the genome (or genetic blueprint) of Neanderthals, which shows that our extinct cousins made "very little, if any" contribution to human genes."

"We are all connected; to each other biologically, to the earth chemically, to the rest of the universe atomically."

"So you're made of detritus [from exploded stars]. Get over it. Or better yet, celebrate it. After all, what nobler thought can one cherish than that the universe lives within us all?"
-Neil DeGrasse Tyson

Just for grins, thought I'd post this nicely done little edit of Quest for Fire.

As far as I could see thus far, that article implied, but did not outright state, that the new sequencing was of Neanderthal nuclear DNA, not of more of the easier-to-find MtDNA. I'm almost certain that this is about nuclear DNA, but I wish it had been stated clearly.

Edit. I missed this:
The draft genome of "nuclear" DNA found in the center of cells required mapping 3.7 million gene elements...
63% is very fine progress, considering the fractured nature of the old genetic material. This is a really big deal, something that might have seemed forever impossible just a few years ago.

Just imagine: Once the sequencing is complete, there may come a day when our understanding of gene expression may allow us to generate Neanderthals in computer simulations.
