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: Geochemical analysis of the epigenetic coating over the engravings and experimental replication show that the engraving was made before accumulation of the archaeological layers, and that most of the lines composing the design were made by repeatedly and carefully passing a pointed lithic tool into the grooves, excluding the possibility of an unintentional or utilitarian origin.

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.

TL;DR: The discovery of three stratified and buried archaeological sites in the Nefud Desert is described, which includes the oldest dated occupation for the region and stone tool assemblages are identified as a Middle Palaeolithic industry that includes Levallois manufacturing methods and the production of tools on flakes.

TL;DR: It is found that the Sahara was not uniformly ameliorated between ~130 and 75 thousand years ago (ka), as has been stated, and populations at the Eurasian gateway were strongly structured, which has implications for refining the demographic parameters of dispersals out of Africa.
