There are a lot of caveats, but a Stone Age genome makes humanity look old.

Genetic variants linked to Alzheimer’s disease and heavy smoking are less frequent in people with longer lifespans, suggesting that natural selection is weeding out these unfavorable variants in some populations, according to an analysis of the genomes of 210,000 people in the U.S. and UK.
In a paper published in the journal Genome Biology and Evolution, University of Houston Professor Dan Graur says that the functional portion of the human genome probably falls between 10% and 15%, with an upper limit of 25%. These figures are very different from one (about 80%) given in 2012 by the Encyclopedia of DNA Elements (ENCODE) project, but more optimistic than the 2014 estimate (8.2%) by Rands et al.
We’ve been swapping DNA for a long time.
When our ancestors first migrated out of Africa around 60,000 years ago, they were not alone. At that time, at least two other species of hominid cousins walked the Eurasian landmass—Neanderthals and Denisovans.
Their descendants live on.
At Jef Boeke’s lab, you can whiff an odor that seems out of place, as if they were baking bread here.
The effort completed in 2003 used the best technology available but now scientists could do more
