Looking back on 2014, month by month, summing up the news — by the numbers.
According to a study published in the journal Science, at least 20% of the Neanderthal genome can be found in modern-day Europeans and Asians. Between 1% and 3% percent of human DNA comes from Neanderthals. “Individually, we are a little bit Neanderthal,” Joshua M. Akey, lead author of the study, told the Los Angeles Times.
By putting together these fragments of DNA, collected from 379 European and 286 East Asian subjects who took part in the analysis, they recovered about 20% of the Neanderthal genome, although subjects from East Asia retained more of it than Europeans.
