The study identifies areas of archaeological significance and provides insights into the impact of climate-driven geography on human dispersal.
Researchers at Nagoya University uncover a complex process of cultural change involving multiple stages, contradicting the 'revolution' theory on Homo sapiens' technological advancements. The study highlights the emergence of bladelet technology in the Early Upper Paleolithic as a key milestone.
A recent study reveals that past climate changes and vegetation shifts played a key role in determining when and where early human species interbred. The research suggests that the overlap of habitats led to increased encounters and interactions among groups, increasing the chance of interbreeding.
A team from Kennesaw State University is studying the cultural, historical, and health significance of artisanal alcohol production in Cabo Verde. The researchers aim to understand the economic, social, and environmental impacts of grogue production, a national liquor produced by fermenting sugar cane.
Researchers found that the spotted lanternfly population is largely due to human-mediated dispersal via transportation. The insects can hitchhike on cars, trucks, and trains, making this a critical time of year for monitoring and removal. Public education and outreach are crucial to slowing the spread.
A world-first model highlights favourable routes for Neanderthals and modern humans to expand eastwards into Asia during humid periods. The research identifies two pathways, one through the Alborz and Kopet Dagh Mountains and another along the Zagros Mountains towards Pakistan and Afghanistan.
Climate variability in eastern Africa influenced hominin evolution, leading to anatomically distinct groups and modern human separation. Researchers analyzed lake sediment cores, revealing stable humid conditions, abrupt arid pulses, and extreme environmental shifts.
A new University of Toronto study finds an additional 514 deaths should be added to the official Hurricane Maria death toll due to displaced Puerto Ricans in the US. The study suggests undercounting and highlights the need for equitable disaster preparedness and cross-jurisdiction data sharing.
Researchers at the University of Tsukuba found that allowing cross-border evacuations can reduce evacuation time by 14% and improve public safety. However, intermunicipal cooperation is required to make this approach effective.
