47. Two digs are consistently cited as offering the first ‘proof’ of prehistoric warfare. The first is Jebel Sahaba in northern Sudan, where in 1964 archaeologists found sixty-one skeletons dating back approximately thirteen thousand years, of which twenty-one bore traces of a violent death. More recent analysis reduces this number to four. See Robert Jurmain, ‘Paleoepidemiolgical Patterns of Trauma in a Prehistoric Population from Central California’, American Journal of Physical Anthropology (12 April 2001). The people of Jebel Sahaba lived on the fertile banks of the Nile and built a necropolis for their dead, making it probable that they were already living in settlements. The second frequently mentioned site is Naturuk, near Lake Turkana in Kenya, where twenty-seven skeletons (bearing traces of violence) were found, estimated to be ten thousand years old. When archaeologists published this discovery in Nature in 2016, global media seized on it as the definitive ‘proof’ that humans are innately warlike creatures. But the significance of the Naturuk find is still contested. Numerous archaeologists have pointed out that the banks of Lake Turkana were a fertile location where hunter-gatherers converged, making it quite plausible that they had already consolidated their belongings and given up their nomadic lifestyle. A few months after this article appeared, Nature published a reaction from another team of archaeologists who questioned the validity of the conclusion that these ‘victims’ had met a violent end at all. This latter article went ignored by most media. See Christopher M. Stojanowski et al., ‘Contesting the Massacre at Nataruk’, Nature (24 November 2016). Even without these controversies, it is important to realise that–apart from Jebel Sahaba and Naturuk–there is no evidence for any prehistoric war, in stark contrast to the surfeit of uncontroversial archaeological evidence (in the form of cave paintings and mass graves) for war in the period after humans began living in permanent settlements and farming.

9. It probably wouldn’t have been possible to rein in overconfident chieftains without the simple yet effective innovation of projectile weapons, which is to say we learned to throw stones, hurl spears and shoot arrows. Comparison of excavated Homo skeletons shows that, over time, our shoulders and wrists evolved, making us better pitchers. Whereas humans have very good aim, chimpa
nzees and orangutans do not (an angry chimp might occasionally throw things, but usually misses). Archaeologists think our projectile weapons were probably quite a bit more refined than anything Neanderthals had. According to evolutionary anthropologist Peter Turchin, this should be considered the pivotal invention in the history of humankind, even outranking fire, farming and the wheel. Without projectile weapons, more aggressive members of our species would have had significantly more offspring and Homo puppy could never have domesticated itself.
10. Individually, foragers prefer the company of their own kin. If men have sole authority, they favour their own families. If men and women share authority, however, they have to compromise. They’ll want to live with both sides of the family, resulting in a more complex social network. This is exactly what we see among nomadic hunter-gatherers. See M. Dyble et al., ‘Sex Equality Can Explain the Unique Social Structure of Hunter-Gatherer Bands’, Science, Vol. 348, Issue 6236 (15 May 2015).

Marriage dovetails perfectly with our nature, Homo puppy being one of the few mammals to engage in ‘pair binding’–aka romantic love. Granted, we’re not all heroes at staying faithful till death do us part, but the science says that a loving relationship is a universal human desire. See Christakis, Blueprint, p. 168.
