It is tempting to see human evolution through the prism of technological breakthroughs that brought tangible material benefits. When our ancestors learned to make projectile weapons, for instance, they could hunt more effectively and secure more reliable sources of meat. Softer aspects of life, such as the ways we socialise, might seem less important to the success of our species. But Lynn, who is based at the University of Alabama, says we socialise not because we like to, but because we need to.
