They also found that hundreds of other genes were turned on in Neanderthals, but are off in people living today. Among the hundreds: genes that control the shape of limbs and the function of the brain, traits where modern humans and Neanderthals differ most. &quot;People are fundamentally interested in what makes us human, in what makes us different from Neanderthals,&quot; said Sarah Tishkoff, an expert in human evolution at the University of Pennsylvania, who was not involved in the new study.</p><br clear="all"/>
