Ancient humans not to blame for mass island extinction

Ancient humans not to blame for mass island extinction 4 May 2021 Human arrival had minimal impacts on biodiversity loss. An international research team has debunked a popular theory that ancient humans caused mass animal and plant extinctions on newly inhabited islands.  Archaeologists and palaeontologists, including from Griffith University and The Australian National University (ANU), compared records of human arrival and extinctions on islands spanning the past 2.6 million years, finding little overlap between the two events.   Co-researcher and ANU Professor Sue O Connor said the evidence did not reveal early modern humans to be the destructive agents that they re often portrayed to be .  

Ancient Australian superhighways suggested by massive supercomputing study | Science

Share Uluru, also known as Ayers Rock, is just one example of a prominent landmark that the earliest people in Australia could have used as a navigational aid. Simon Bradfield/iStock Ancient Australian ‘superhighways’ suggested by massive supercomputing study May. 4, 2021 , 3:05 PM When humans first set foot in Australia more than 65,000 years ago, they faced the perilous task of navigating a landscape they’d never seen. Now, researchers have used supercomputers to simulate 125 billion possible travel routes and reconstruct the most likely “superhighways” these ancient immigrants used as they spread across the continent. The project offers new insight into how landmarks and water supplies shape human migrations, and provides archaeologists with clues for where to look for undiscovered ancient settlements.
