TL;DR: It is argued that the chronology and physical diversity of Pleistocene human fossils and the African archaeological record support an emerging view of a highly structured African prehistory that should be considered in human evolutionary inferences, prompting new interpretations, questions, and interdisciplinary research directions.

TL;DR: The emerging picture of the dispersal process suggests dynamic behavioral variability, complex interactions between populations, and an intricate genetic and cultural legacy in Homo sapiens out of Africa.

TL;DR: The emerging picture of Arabia suggests that numerous dispersals of hominin populations into the region occurred, and subsequently followed autochthonous trajectories, creating a distinctive regional archeological record.

TL;DR: Al Wusta shows that early H. sapiens dispersals out of Africa were not limited to winter rainfall-fed Levantine Mediterranean woodlands immediately adjacent to Africa, but extended deep into the semi-arid grasslands of Arabia, facilitated by periods of enhanced monsoonal rainfall.

TL;DR: In this paper, the authors evaluate the palaeoenvironmental setting for hominin dispersals between, and within, northeast Africa and southwest Asia during Marine Isotope Stages (MIS) 7-5 using reconstructions of surface freshwater availability as an environmental proxy.
