TLDR
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.About:

Critical reassessment of putative Acheulean Porosphaera globularis beads
TL;DR: Acheulean sponges belonging to the Late Cretaceous species Porosphaera globularis have been interpreted as the oldest known beads by some researchers as mentioned in this paper, however, this seems contradicted by the fact that according to Smith, W.G. [1884] the specimens bearing microchipping and abrasions were found by him and ‘‘not touched or manipulated by the workmen''.

Abstract: In this study, we compared the effectiveness of instrumental neutron activation analysis (INAA) of bulk ochre to laser ablation-inductively coupled plasma mass spectrometry of homogenized ochre chips (HOC LA–ICPMS) at distinguishing among three ochre sources in northern Malawi. Both techniques upheld the Provenance Postulate; however, HOC LA–ICPMS required less sample material than INAA and facilitated fast, inexpensive replicate observations that allowed for more robust statistical analysis. Our results indicated that HOC LA–ICPMS is a maturing technique that will be a valuable option for analysing artefacts that require minimally destructive sampling but are too large to fit into the laser cell for direct ablation. With regard to the statistical procedures used, stepwise canonical discriminant analysis was demonstrated to be a highly effective method for distinguishing among ochre sources, even in the presence of significant intra-source and intra-sample heterogeneity. Continued development of the HOC sample preparation technique will expand the range of archaeological ochre artefacts that can be included in provenance studies and prevent bias towards artefacts of convenient-to-analyse dimensions.

New Experiments and a Model-Driven Approach for Interpreting Middle Stone Age Lithic Point Function Using the Edge Damage Distribution Method.
TL;DR: This study provides a method with which landscape-scale questions of early modern human tool-use and site-use can be addressed and provides evidence for variable MSA behavioral strategies of stone point utilization on the landscape consistent with armature tips at KP1, and cutting tools at PP13B and DK1, as well as damage contributions from post-depositional sources across assemblages.

Experimental and archaeological investigations of backed microlith function among Mid-to-Late Holocene herders in southwestern Kenya
TL;DR: In this article, an experimental and comparative approach was taken to evaluate the circumstances driving the deployment of microlithic tool technologies by food-producing mobile herders during the mid-to-late Holocene in southern Kenya.
The Major Transitions in the History of Human Transformation of the Biosphere
TL;DR: In this article, the authors provide a new framework for the research in the history of human transformation of the biosphere, focusing on the major transitions which resulted in a considerable increase in our species' impact on the Biosphere (in relation to the state before the transition).

Age dating and the orbital theory of the ice ages: Development of a high-resolution 0 to 300,000-year chronostratigraphy
Douglas G. Martinson,Nicklas G Pisias,James D. Hays,John Imbrie,Theodore C. Moore,Nicholas J Shackleton +5 more
TL;DR: Using the concept of "orbital tuning", a continuous, high-resolution deep-sea chronostratigraphy has been developed spanning the last 300,000 yr as mentioned in this paper.

Mitochondrial DNA and human evolution
TL;DR: All these mitochondrial DMAs stem from one woman who is postulated to have lived about 200,000 years ago, probably in Africa, implying that each area was colonised repeatedly.
