The earliest indication of Upper Palaeolithic modern human migration into Europe is a series of modern human teeth with Neronian industry stone tools found at Mandrin Cave, Malataverne in France, dated in 2022 to between 56,800 and 51,700 years ago. The Neronian is one of the many industries associated with modern humans classed as transitional ...
Based on a dataset of average population density of hunter-gatherer groups collected by Lewis R. Binford, which indicate a mean density of 0.1223 humans per km 2 and a median density of 0.0444 humans per km 2, the combined human population of Africa and Eurasia at the time of the LGM would have been between 2,998,820 and 8,260,262 people.
A scanner used to measure bone density using dual energy X-ray absorptiometry. Bone density, or bone mineral density, is the amount of bone mineral in bone tissue.The concept is of mass of mineral per volume of bone (relating to density in the physics sense), although clinically it is measured by proxy according to optical density per square centimetre of bone surface upon imaging.

It was first described in the scientific literature by David Eberth, Donald Brinkman, and Vaia Barkas in 2010 after more than ten years of research. The Hilda mega-bonebed is significant because the behavior of the preserved dinosaurs themselves was the dominant cause of its existence, rather than the stratum's geological history like most ...
A bone point, a possible arrowhead that pushes back the origin of bow and bone arrow technology to 61,000 BP, at least 20,000 years earlier than the previous earliest example; [20] [21] The earliest known bone needle , dated to 61,000 BP, with wear similar to that found in bone needles used to puncture animal hide ; [ 20 ]
The seven footprints, found amidst a clutter of hundreds of prehistoric animal prints, are estimated to be 115,000 years old. Many fossil and artifact windfalls have come from situations like this ...
About 10 million people age 50 years and older in the U.S. have osteoporosis, a disease that weakens bones, causing them to more easily break. While the majority are women, about 2 million are men.
An artist's rendering of a temporary wood house, based on evidence found at Terra Amata (in Nice, France) and dated to the Lower Paleolithic (c. 400,000 BP) [5]. The oldest evidence of human occupation in Eastern Europe comes from the Kozarnika cave in Bulgaria where a single human tooth and flint artifacts have been dated to at least 1.4 million years ago.
