Runaway Social Selection in Human Evolution
2022
Frontiers in Ecology and Evolution
Darwin posited that social competition among conspecifics could be a powerful selective pressure. Alexander proposed a model of human evolution involving a runaway process of social competition based on Darwin's insight. Here we briefly review Alexander's logic, and then expand upon his model by elucidating six core arenas of social selection that involve runaway, positive-feedback processes, and that were likely involved in the evolution of the remarkable combination of adaptations in humans.
