Humans are the result of 'braided' genetic streams, not a 'tree' of evolution
A new paper explores humankind’s ‘braided’ stream of evolution, the result of genetic admixture when Neanderthals and other ancient groups met and mixed in ancient times.

Standardization can be applied to a lithic assemblage via raw material selection, blank production, blank selection, and/or retouch. Here we explore the baseline level of morphological standardization achievable through blank production alone. By quantifying how little morphological variability is inherently involved in different blank-producing lithic technologies that span much of the Stone Age, we seek to gain a long-term perspective on the evolution of lithic standardization. 728 flakes were knapped from 26 cores of 7 different lithic technologies: bipolar, multiplatform, discoidal, Levall...
CS:GO players have officially been killing each other since the time of the first cave paintings, as Steam stats reveal the huge hours poured into Valve’s FPS
The reconstruction of the original morphology of bones and teeth after sampling for physicochemical (e.g., radiocarbon and uranium series dating, stable isotope analysis, paleohistology, trace element analysis) and biomolecular analyses (e.g., ancient DNA, paleoproteomics) is appropriate in many contexts and compulsory when dealing with fossil human remains. The reconstruction protocols available to date are mostly based on manual re-integration of removed portions and can lead to an imprecise recovery of the original morphology. In this work, to restore the original external morphology of sam...
British researchers say the ancient engravings of animals on the flat surfaces of stones known as plaquettes appear to move when exposed to flickering flames of a hearth fire.
