An international research project led by the Institute of Evolutionary Biology (IBE: CSIC-UPF) has created the largest genomic database of Native Americans. Spanish National Research Council (CSIC) —Research into human genomic diversity has a number of applications in biomedicine, evolution, and history. However, many populations have historically been underrepresented on the human genomic map. This is the case of Native American populations, whose history of adaptation and genetic [...]

George Washington University, WASHINGTON (Nov. 4, 2025) —Imagine early humans meticulously crafting stone tools for nearly 300,000 years, all while contending with recurring wildfires, droughts, and dramatic environmental shifts. A recent study, published in Nature Communications, brought to light remarkable evidence of enduring technological tradition from Kenya’s Turkana Basin. An international multi-center research team has uncovered at the Namorotukunan Site one of the oldest [...]

Human hunting drove the extinction of large-bodied terrestrial sloths. American Association for the Advancement of Science (AAAS) —Ancient sloths ranged in size from tiny climbers to ground-dwelling giants. Now, researchers report this body size diversity was largely shaped by sloths’ habitats, and that these animals’ precipitous decline was likely a result of increasing human pressures, which also triggered the extinction of the large-bodied ground-dwelling animals. [...]

A new analysis suggests our language capacity existed at least 135,000 years ago, with language used widely perhaps 35,000 years after that. Massachusetts Institute of Technology —It is a deep question, from deep in our history: When did human language as we know it emerge? A new survey of genomic evidence suggests our unique language capacity was present at least 135,000 years ago. Subsequently, language might have entered social use 100,000 years ago. Our species, Homo sapiens, is [...]

Universitat Autonoma de Barcelona —A pre-Columbian society in the Amazon developed a sophisticated agricultural engineering system that allowed them to produce maize throughout the year, according to a recent discovery by a team of researchers from the Institute of Environmental Science and Technology (ICTA-UAB) and the Department of Prehistory at the Universitat Autònoma de Barcelona, (Spain); the Universities of Exeter, Nottingham, Oxford, Reading and Southampton (UK); the [...]

Conny Waters - AncientPages.com - More than 10,000 Pre-Columbian archaeological sites likely rest undiscovered throughout the Amazon basin, estimates a new study. Geographical distribution of known and newly discovered pre-Columbian geometric earthworks in Amazonia. (A) Map of previously reported and newly discovered earthworks (purple circles and yellow stars, respectively) reported in this study across six Amazonian regions: central Amazonia (CA), eastern Amazonia (EA), Guiana Shield (GS), [...]

An investigation covering four different parts of Brazil carried out analysis of genomic data from 34 fossils, including larger skeletons and the famous mounds of shells and fishbones built on the coast, and revealed differences between communities. FUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO—An article* published on July 31 in Nature Ecology & Evolution reveals that Luzio, the oldest human skeleton found in São Paulo state [...]
