An international team led by Harvard Medical School scientists has produced the first genome-wide ancient human DNA sequences from west and central Africa. The data, recovered from four individuals buried at an iconic archaeological site in Cameroon between 3,000 and 8,000 years ago, enhance our understanding of the deep ancestral relationships among populations in sub-Saharan … Read more
A new study in the journal Nature Sustainability overturns long-held interpretations of the role humans played in shaping the American landscape before European colonization. The findings give new insight into the rationale and approaches for managing some of the most biodiverse landscapes in the eastern U.S. The study, led by archaeologists, ecologists, and paleoclimatologists at Harvard, Emerson … Read more
A new species of prehistoric scorpion from the early Siluarian period (approximately 437.5 to 436.5 million years ago) is described in a study in Scientific Reports. The findings suggest that Parioscorpio venator is the oldest-known scorpion reported to date and may have been capable of leaving its marine habitat and venturing onto land, a behaviour similar … Read more
Human behaviour is influenced by many things, most of which remain unconscious to us. One of these is a phenomenon known among perception psychologists as “pseudo-neglect”. This refers to the observation that healthy people prefer their left visual field to their right and therefore devide a line regularly left of centre. A study published on … Read more
Christopher Columbus’ accounts of the Caribbean include harrowing descriptions of fierce raiders who abducted women and cannibalized men – stories long dismissed as myths. But a new study suggests Columbus may have been telling the truth. Using the equivalent of facial recognition technology, researchers analyzed the skulls of early Caribbean inhabitants, uncovering relationships between people groups and … Read more
The research, published in the Journal of Royal Society Interface, shows that Palaeolithic hominins selected different raw materials for different stone tools based on how sharp, durable and efficient those materials were. They made these decisions in conjunction with information about the length of time the tools would be used for and the force with which … Read more
New evidence reported from the Maldives, in the Indian Ocean, shows that sea level has not been stable over the passed 2,000 years but has varied by up to 0.9m on two occasions. Records of sea level change over the past 2,000 years from the Atlantic and Pacific oceans show sea level has been stable, … Read more
The 170,000-year-old charred remains of starchy plant parts from Border Cave, South Africa provides the earliest direct evidence for the collecting and cooking of carbohydrate-rich rhizomes, a new study reports. The findings suggest that palatable rhizomes from Hypoxis sp.– a genus of small flowering plants – may have been a reliable and transportable staple food for Middle … Read more
Without a doubt, Tyrannosaurus rex is the most famous dinosaur in the world. The 40-foot-long predator with bone crushing teeth inside a five-foot long head are the stuff of legend. Now, a look within the bones of two mid-sized, immature T. rex allow scientists to learn about the tyrant king’s terrible teens as well. In the early … Read more
The new study by paleontologists from the University of Chicago, published this week in the Proceedings of the National Academy of Sciences, uses CT scanning to examine the shape and structure of fin rays while still encased in surrounding rock. The imaging tools allowed the researchers to construct digital 3D models of the entire fin of … Read more
