New Studies Find Many Genes Influence Left- or Right-Handedness Scientists have long-posited that one single gene may determine whether a person is left- or right-handed (the latter, of course, being dominant, with 90% of people favoring their right). This theory does take into account the fact that environment factors (including geography and culture) likely play a critical role, too. Now, however, several studies involving millions …
Scientists have long-posited that one single gene may determine whether a person is left- or right-handed (the latter, of course, being dominant, with 90% of people favoring their right). This theory does take into account the fact that environment factors (including geography and culture) likely play a critical role, too. Now, however, several studies involving millions of participants reveal that dozens of genetic variations may …
From a one inch wad of birch pitch, chewed and spat out by a hunter-gatherer referred to as Lola around the year 3,700 BC, scientists were able to piece together an entire genetic snapshot—which goes so far as to include the meal she ate that day. The findings were published in the journal Nature Communications and represent the first time researchers “have been able to …
