TLDR
Fossilized hominid crania from Herto, Middle Awash, Ethiopia are described and provide crucial evidence on the location, timing and contextual circumstances of the emergence of Homo sapiens.Abstract:
The origin of anatomically modern Homo sapiens and the fate of Neanderthals have been fundamental questions in human evolutionary studies for over a century. A key barrier to the resolution of these questions has been the lack of substantial and accurately dated African hominid fossils from between 100,000 and 300,000 years ago. Here we describe fossilized hominid crania from Herto, Middle Awash, Ethiopia, that fill this gap and provide crucial evidence on the location, timing and contextual circumstances of the emergence of Homo sapiens. Radioisotopically dated to between 160,000 and 154,000 years ago, these new fossils predate classic Neanderthals and lack their derived features. The Herto hominids are morphologically and chronologically intermediate between archaic African fossils and later anatomically modern Late Pleistocene humans. They therefore represent the probable immediate ancestors of anatomically modern humans. Their anatomy and antiquity constitute strong evidence of modern-human emergence in Africa.read more

TL;DR: This article attempts to date the conditions, terms and places of the first emergence of the main human viral epidemics (HIV, influenza, measles, smallpox), supported by genetically mitigated heterozygous forms of infections.

Lithic Variability and Cultures in the East African Middle Stone Age
TL;DR: In this article, the relation between lithic variability in the East African MSA and its meaning in terms of the structure of human groups is investigated, critical for interpreting the behavioral and evolutionary processes that led to Homo sapiens expansion within and out of Africa.

Zooarchaeology of the Middle Stone Age in Magubike Rockshelter, Iringa Region, Tanzania
TL;DR: The analysis of the faunal remains from Middle Stone Age deposits of Magubike rockshelter was undertaken to contribute to the modern human behavior debate as discussed by the authors, which implicates hominins as the key taphonomic agent in the accumulation and modification of the Faunal assemblage.

TL;DR: A set of unique event polymorphisms associated with the non‐recombining portion of the Y‐chromosome (NRY) addresses this issue by providing evidence concerning successful migrations originating from Africa, which can be interpreted as subsequent colonizations, differentiations and migrations overlaid upon previous population ranges.

Out of Africa again and again.
TL;DR: A coherent picture of recent human evolution emerges with two major themes: first is the dominant role that Africa has played in shaping the modern human gene pool through at least two—not one—major expansions after the original range extension of Homo erectus out of Africa, and second is the ubiquity of genetic interchange between human populations.
