We challenge the view that our species, Homo sapiens, evolved within a single population and/or region of Africa. The chronology and physical diversity Pleistocene human fossils suggest morphologically varied populations pertaining to H. sapiens clade lived throughout Similarly, African archaeological record demonstrates polycentric origin persistence regionally distinct material culture in variety paleoecological settings. Genetic studies also indicate present-day structure Africa extends...
The manufacture of flaked stone artifacts represents a major milestone in the technology human lineage. Although earliest production primitive tools, predating genus Homo and emphasizing percussive activities, has been reported at 3.3 million years ago (Ma) from Lomekwi, Kenya, systematic sharp-edged tools is unknown before 2.58-2.55 Ma Oldowan assemblages Gona, Ethiopia. organized part suite characteristics that often associated with adaptive grade shift linked to Recent discoveries...
Abstract Multiple lines of genetic and archaeological evidence suggest that there were major demographic changes in the terminal Late Pleistocene epoch early Holocene sub-Saharan Africa 1–4 . Inferences about this period are challenging to make because shifts past 5,000 years have obscured structures more ancient populations 3,5 Here we present genome-wide DNA data for six individuals from eastern south-central spanning approximately 18,000 (doubling time depth African DNA), increase quality...
The habitual consumption of large-animal resources (e.g., similar sized or larger than the consumer) separates human and nonhuman primate behavior. Flaked stone tool use, another important hominin behavior, is often portrayed as being functionally related to this by necessity a sharp edge for cutting animal tissue. However, most research on both issues emphasizes sites that postdate ca. 2.0 million years ago. This paper critically examines theoretical significance earlier origins these two...
Early modern humans fundamentally altered ecology and landscapes in southern-central Africa using fire.
Studies of bone surface modifications (BSMs) such as cut marks are crucial to our understanding human and earlier hominin subsistence behavior. Over the last several decades, however, BSM identification has remained contentious, particularly in terms identifying earliest instances butchery; there been a lack consensus over how identify or differentiate made by non-human actors varying effectors. Most investigations have relied on morphology butchery their patterning. This includes marks, one...
The identification of butchery marks in the zooarchaeological record has consistently been debated. Much experimental work done to understand causal agents behind some bone surface modifications, but recent controversies show that there is still no consensus. Terminology not consistent between researchers, and ambiguity how characteristics are described interpreted. There also a lack understanding what causes individual variables within made by different agents, which compounded mark...
This opinion piece argues that Homo sapiens evolved within interlinked groups living across Africa, and not in a single region of East Africa. Millennia separation gave rise to diversity human forms, complex mix archaic modern features different places at times over the last 300,000 years ultimately shaped our species.
Relatively little is known about Nubia's genetic landscape prior to the influence of Islamic migrations that began in late 1st millennium CE. Here, we increase number ancient individuals with genome-level data from Nile Valley three 69, reporting for 66 two cemeteries at Christian Period (~650-1000 CE) site Kulubnarti, where multiple lines evidence suggest social stratification. The Kulubnarti Nubians had ~43% Nilotic-related ancestry (individual variation between ~36-54%) remaining...
We argue for implementation of informed proxy or relational autonomy consent in human aDNA research, where the deceased may be represented by living people research affects. Embracing underlying principles and process has potential to transform (1) enriching outcomes learning from collaborating with interested affected persons; (2) empowering potentially impacted stipulate evidence information flow; (3) guarding researchers against actual perceived violations providing a common set...
Abstract Aim Palaeoecological data are crucial to understanding the historical extinction of blue antelope ( Hippotragus leucophaeus ). This study examined late Quaternary fossil evidence bearing on antelope's calving and migratory habits. Location Cape Floristic Region CFR ), South Africa. Methods Blue mortality patterns were reconstructed from dental remains assemblages spanning last c . 200,000 years located in 's winter year‐round rainfall zones. Two demographic measures examined: (1)...
The Southern Montane Forest-Grassland mosaic ecosystem in the humid subtropics southern Rift Valley of Africa comprised environmental context for a large area which modern human evolution and dispersal occurred. Variable climatic conditions during Late Pleistocene have ranged between hyperarid, changing character transforming it at different points time into barrier, refuge, corridor eastern African populations. Alluvial fans presently blanket areas adjacent to major river systems, were key...
