    ABSTRACT: The present paper examined the assumption of strong reproductive isolation (RI) between Homo neanderthalensis and Homo sapiens, as well as the question of what form it might have taken, using insights from the parallel case of chimpanzee–bonobo hybridization. RI from hybrid sterility or inviability was thought unlikely based on the short separation-to-introgression timeline. The forms of RI that typically develop in primates have relatively short timelines (especially for partial implementation); they generally preclude mating or influence hybrid survival and reproduction in certain contexts, and they have the potential to skew introgression directionality. These RI barriers are also consistent with some interpretations of the archaeological and fossil records, especially when behavioral, cognitive, morphological, and genetic differences between the two human species are taken into consideration. Differences potentially influencing patterns of survival and reproduction include interspecies violence, Neandertal xenophobia, provisioning behavior, and ontogenetic, morphological, and behavioral differences affecting matters such as kin and mate recognition, infanticide, and sexual selection. These factors may have skewed the occurrence of interbreeding or the survival and reproduction of hybrids in a way that might at least partially explain the pattern of introgression.

    ABSTRACT: For a human population geneticist, an interest in Africa hardly requires an explanation. With the highest time depth of human history and over 2000 linguistic groups spreading across highly diverse geographical settings, Africa harbors a tremendous variety of genetic patterns that remain to be explained. My own interest in African populations started with São Tomé, a tiny plantation island located at the heart of the Gulf of Guinea that was peopled by slaves imported from the adjacent areas of the mainland. Presently, I am still interested in insular populations related to the slave trade, like the Cape Verde Archipelago, facing Senegal. Moreover, I became involved in the study of genetic diversity of continental areas like Angola and Mozambique, lying at the southwestern and southeastern edges of the Bantu expansions, respectively. The area of Angola, in particular, is especially interesting for understanding the push of Bantu-speaking peoples out of the rain forest into the arid steppes of southwestern Africa. In southern Angola, the cultural and geographical proximity between Bantu and Khoisan cattle herders poses intriguing questions about the development of the relatively isolated Southwest African pastoral scene and the nature of the interactions between the vanguard of the Bantu expansions and the non-Bantu peoples from the desert.
