 Kekinian hunter-gatherers provide our best guess at how early humans and Neanderthals lived. People like the Namibia's Khoisan and Tanzania's Hadzabe gather kerabates into wandering bands of ten to 60 people. The bands combine into a loosely organised tribe of a thousand people or more.

Neanderthal societies may have been similar but with one crucial difference: smaller social grups. Tight-knit tribes What points to this is evidence that Neanderthals had lower genetic diversity. King88bet slot login In small populations, genes are easily lost. If one individu in ten carries a gene for curly hair, then in a ten-person band, one death could remove the gene from the population. In a band of fifty, five people would carry the gene - multiple backup copies. So over time, small grups tend to lose genetic variation, ending
