Research into differences between chimpanzees and bonobos in 鈥榩reparation鈥 for tool use reveals intriguing sex bias in object manipulation in young chimpanzees 鈥 one that is partly mirrored in human children.
First evidence for a species difference in the innate predisposition for tool use in our closest evolutionary cousins could provide insight into how humans became the ultimate tool-using ape.
New research shows that males with higher 鈥榬eproductive potential鈥 are better distance runners. This may have been used by females as a reliable signal of high male genetic quality during our hunter-gatherer past, as good runners are more likely to have other traits of good hunters and providers, such as intelligence and generosity.
Analysis of a latrine in Jerusalem that dates back over 500 years finds human parasites common in northern Europe yet very rare in Middle East at the time, suggesting long-distance trade or pilgrimage routes and shedding light on prevalent infectious diseases of the age.
Wealth and power may have played a stronger role than 鈥渟urvival of the fittest鈥.
Researchers used the new survey of the Messak Settafet to estimate that enough stone tools were discarded over the course of human evolution in Africa to build more than one Great Pyramid for every square kilometre of land on the continent.
Latest analysis of prehistoric bones show there is no anatomical reason why a person born today could not develop the skeletal strength of a prehistoric forager or a modern orangutan. Findings support the idea that activity throughout life is the key to building bone strength and preventing osteoporosis risk in later years, say researchers.
A genome taken from a 36,000 year old skeleton reveals an early divergence of Eurasians once they had left Africa, and allows scientists to better assess the point at which 鈥榓dmixture鈥 - or interbreeding - between Eurasians and Neanderthals occurred. 探花直播latest research also points to a previously unknown population lineage as old as the first population separations since humans dispersed out of Africa.
New research shows that chimpanzees search for the right tools from a key plant species when preparing to 鈥榓nt dip鈥 - a crafty technique enabling them to feast on army ants without getting bitten. 探花直播study shows that army ants are not a poor substitute for preferred foods, but a staple part of chimpanzee diets.
Research led by the 探花直播 of Leicester, working with the 探花直播 of Cambridge, Loughborough 探花直播 and 探花直播 Hospitals of Leicester, has finally uncovered the truth about Richard III鈥檚 spinal condition.
