|At least eight genes that rose to prominence in human DNA since the time of the ancient relatives, called Denisovans, affect nerve growth and language... The cognitive power conferred by these genes may have keyed the development of complex thinking skills, culture and civilization... Almost every cell in an organism holds a complete copy its genome, the chemical code for making proteins and tissues... Eight are linked to genes involved in brain function, the study said. Four of these genes -- called SLITRK1, KATNA1, ARHGAP32 and HTR2B -- are known to be involved in nerve growth and function... Human intelligence relies on the brain's ability to link ideas, memories and experiences through its networks of neurons... These genes may provide some explanation for modern humans' ability to see things from another person's viewpoint, as well as to conceal things and lie...|
