we’re more neandertal than we thought


modern people of european and asian ancestry carry slightly more neandertal dna than previously realized.about 1.8 to 2.6 percent of dna in non-africans is an heirloom of ancient human-neandertal interbreeding, researchers report online october 5 in science. that corresponds to 10 to 20 percent more neandertal ancestry than previous estimates — and it may carry consequences for human health and behavior, say paleogeneticist janet kelso of the max planck institute for evolutionary anthropology in leipzig, germany, and colleagues. analysis of dna from an about 50,000-year-old neandertal woman from vindija cave in croatia allowed kelso and colleagues to find the extra ancestry contribution. among the gene variants modern humans inherited from neandertals are ones associated with higher chol..






you may be more 'neanderthal' than you thought


the genome of a female neanderthal, whose bones were found in the vindija cave in croatia (shown here), revealed our extinct relatives passed along genes that play roles in many diseases today.  (© mpi f. evolutionary anthropology/ j. krause) a female neanderthal who lived in what is now croatia 52,000 years ago is revealing that our "caveman" relatives may have passed on genes that play roles in cholesterol levels, eating disorders, arthritis and other diseases today, the researchers who sequenced her genome say.and some modern humans are carrying around more neanderthal dna than scientists had thought: the study found that the genomes of modern human populations that originated outside africa hold between 1.8 and 2.6 percent neanderthal dna. that's much higher...
