TLDR
Stone artifacts from the Bose basin, South China, imply that Acheulean-like tools in the mid-Pleistocene of South China imply that Mode 2 technical advances were manifested in East Asia contemporaneously with handaxe technology in Africa and western Eurasia.Abstract:
Stone artifacts from the Bose basin, South China, are associated with tektites dated to 803,000 ± 3000 years ago and represent the oldest known large cutting tools (LCTs) in East Asia Bose toolmaking is compatible with Mode 2 (Acheulean) technologies in Africa in its targeted manufacture and biased spatial distribution of LCTs, large-scale flaking, and high flake scar counts Acheulean-like tools in the mid-Pleistocene of South China imply that Mode 2 technical advances were manifested in East Asia contemporaneously with handaxe technology in Africa and western Eurasia Bose lithic technology is associated with a tektite airfall and forest burningread more

The revolution that wasn't: a new interpretation of the origin of modern human behavior.
Sally McBrearty,Alison S. Brooks +1 more
TL;DR: The African Middle and early Late Pleistocene hominid fossil record is fairly continuous and in it can be recognized a number of probably distinct species that provide plausible ancestors for H. sapiens, and suggests a gradual assembling of the package of modern human behaviors in Africa, and its later export to other regions of the Old World.
Journal ArticleDOI
Paleolithic Technology and Human Evolution
TL;DR: This work has shown that stone tool technology, robust australopithecines, and the genus Homo appeared almost simultaneously 2.5 million years ago, and once this adaptive threshold was crossed, technological evolution was accompanied by increased brain size, population size, and geographical range.

Earliest Pleistocene hominid cranial remains from Dmanisi, Republic of Georgia: taxonomy, geological setting, and age.
Leo Gabunia,Abesalom Vekua,David Lordkipanidze,Carl C. Swisher,Reid Ferring,Antje Justus,Medea Nioradze,Merab Tvalchrelidze,Susan C. Antón,Gerhard Bosinski,Olaf Jöris,Marie A.De Lumley,Givi Majsuradze,Aleksander Mouskhelishvili +13 more
TL;DR: Paleontological, archaeological, geochronological, and paleomagnetic data from Dmanisi all indicate an earliest Pleistocene age of about 1.7 million years ago, supporting correlation of the new specimens with the Koobi Fora fossils.

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.

Stereospecific alkane hydroxylation by non-heme iron catalysts: mechanistic evidence for an Fe(V)=O active species.
Kui Chen,Lawrence Que +1 more
TL;DR: These studies serve as a synthetic precedent for an Fe(V)=O species in the oxygen activation mechanisms postulated for non-heme iron enzymes such as methane monooxygenase and Rieske dioxygenases.

Intercalibration of standards, absolute ages and uncertainties in 40Ar/39Ar dating

TL;DR: McDougall et al. as mentioned in this paper derived intercalibration factors for McClure Mountain hornblende (MMhb-1), GHC-305 biotite, GA-1550, Taylor Creek sanidine (TCs), relative to Fish Canyon sanidine(ACs), were derived from 797 analyses involving 11 separate irradiations with well-constrained neutronfluence variations.

Age of the earliest known hominids in Java, Indonesia
TL;DR: The hominid fossils, a juvenile calvaria of Pithecanthropus and a partial face and cranial fragments of Meganthropus, commonly considered part of the Asian Homo erectus hypodigm, are at least 0.6 million years older than fossils referred to as Homo erectu from Olduvai Gorge, Tanzania, and comparable in age with the oldest Koobi Fora Homo cf.

The oldowan reassessed: a close look at early stone artifacts
TL;DR: Early Stone Age assemblages called "Oldowan" and early "Developed Oldowan" are discussed, based on the results of a long-term study of Plio-Pleistocene sites at Koobi Fora, Kenya and an extensive experimental research program of replicating and using early stone artifact forms.
