Neanderthal and Denisovan genetic admixture with Eurasian modern humans, and a "signature" of Neanderthal admixture in African populations, are widely accepted "facts". Inferences of admixture are based mainly on the assumption that Yoruba, San and/or Pygmy populations contain all African genetic variation. Variants shared among Neanderthals and modern Eurasians, but not present in these Africans, are assumed to reflect 2-4% admixture. However, genetic diversity and geographic structure are...

This is an abstract from the "SAA 2023: Individual Abstracts" session, at the 88th annual meeting of the Society for American Archaeology. 'Ubeidiya, Central Jordan Valley, Israel, is one of the earliest prehistoric sites outside Africa. Extensive excavations in the second half of the twentieth century yielded important archaeological, paleontological, and geological data, which provided insights into early Pleistocene hominins’ expansion out of Africa. The primary geological descriptions of...

International, interdisciplinary fieldwork is at the core of Lawrence Straus' long-term archaeological research. Inspired by such an approach since my involvement with Straus' excavations at the Abri Dufaure in southwest France, I have been conducting field work in the Arabian peninsula, which aims to understand the relationship between climate change and human demography across the Pleistocene. Satellite images and GIS studies have effectively demonstrated that there were wet phases in this...

Similarities between stone tools in northeast Africa and Southwest Asia are considered to reflect either one or more of a number of processes including technological convergence in similar ecological zones, demic dispersal and cultural transfer/cultural diffusion. However, determining the likelihood of these effects is contingent upon accurate estimates of population size – a variable that is rarely discussed explicitly. In this paper, upper and lower bounds for population sizes in the northeast...
