Human evolution and dispersals of Homo sapiens

I am investigating the relationship between human evolution and temporal advances in technology, and the function of prehistoric stone tools, to better understand the distinctive abilities of Homo sapiens. In particular, I am interested in the reasons why Homo sapiens, who expanded into Eurasia, achieved an increase in population size, whereas indigenous humans went extinct after the arrival of Homo sapiens. As hunting was undeniably an important skill for subsistence for prehistoric hunter-gatherers, I try to elucidate the emergence and dispersal process of complex projectile technology using spearthrowers and bows-and-arrows.
