Surprising similarities in stone tools of early humans and monkeys      (via sciencedaily.com) 

Researchers have discovered artefacts produced by old world monkeys in Thailand that resemble stone tools, which historically have been identified as intentionally made by early hominins. Until now, sharp-edged stone tools were thought to represent the onset of intentional stone tool production, one of the defining and unique characteristics of hominin evolution. This new study challenges long held beliefs about the origins of intentional tool production in our own lineage.

Assessing the potential risks of ocean-based climate intervention technologies on deep-sea ecosystems      (via sciencedaily.com) 

An international team of experts convened remotely as part of the Deep Ocean Stewardship Initiative's Climate Working Group to consider the deep-sea impacts of ocean-based climate intervention (OBCI). A research team has analyzed the proposed approaches to assess their potential impacts on deep-sea ecosystems and biodiversity. Their findings raise substantial concern on the potential impacts of these technologies on deep-sea ecosystems and call for the need for an integrated research effort to carefully assess the cost and benefits of each intervention.

Island-inhabiting giants, dwarfs more vulnerable to extinction      (via sciencedaily.com) 

Island-dwelling mammal species often expand or contract in size, becoming giant or dwarf versions of their mainland counterparts. A new Science study from a global team shows that those giants and dwarfs have faced extreme risk of extinction -- an existential threat exacerbated by the arrival of humans.

Plant roots fuel tropical soil animal communities      (via sciencedaily.com) 

A research team has shed new light on the importance of plant roots for below-ground life, particularly in the tropics. Millions of small creatures toiling in a single hectare of soil including earthworms, springtails, mites, insects, and other arthropods are crucial for decomposition and soil health. For a long time, it was believed that leaf litter is the primary resource for these animals. However, this recent study is the first to provide proof that resources derived from plant roots drive soil animal communities in the tropics.

The world's first horse riders      (via sciencedaily.com) 

Researchers have discovered evidence of horse riding by studying the remains of human skeletons found in burial mounds called kurgans, which were between 4500-5000 years old. The earthen burial mounds belonged to the Yamnaya culture. The Yamnayans had migrated from the Pontic-Caspian steppes to find greener pastures in today's countries of Romania and Bulgaria up to Hungary and Serbia.

Archaeological study of 24 ancient Mexican cities reveals that collective forms of governance, infrastructural investments, and collaboration all help societies last longer      (via sciencedaily.com) 

Some cities only last a century or two, while others last for a thousand years or more. Often, there aren't clear records left behind to explain why. Instead, archaeologists piece together clues from the cities' remains to search for patterns that help account for why certain places retained their importance longer than others.

Wisconsin cave holds tantalizing clues to ancient climate changes, future shifts      (via sciencedaily.com) 

A newly published study of a stalagmite found in Cave of the Mounds reveals previously undetected history of the local climate going back thousands of years. Researchers describe evidence for an ice age punctuated by massive and abrupt warming events across much of the Northern Hemisphere.

Earlier take-off could lead to fewer bumblebees and less pollination      (via sciencedaily.com) 

With the arrival of spring, bumblebee queens take their first wing beat of the season and set out to find new nesting sites. But they are flying earlier in the year, as a result of a warmer climate and a changing agricultural landscape, according to new research.

Waxing and waning of environment influences hominin dispersals across ancient Iran      (via sciencedaily.com) 

A world-first model of paleoclimate and hydrology in Iran has highlighted favourable routes for Neanderthals and modern human expansions eastwards into Asia. The findings reveal that multiple humid periods in ancient Iran led to the expansions of human populations, opening dispersal route across the region, and the possible interactions of species such as Neanderthals and our own Homo sapiens.

Deforestation in the tropics linked to a reduction in rainfall      (via sciencedaily.com) 

Deforestation is resulting in reduced rainfall across large parts of the tropics, according to new research. People living in tropical forest communities have often complained that the climate gets hotter and drier once trees are cleared but until now, scientists have not been able to identify a clear link between the loss of tree cover and a decline in rainfall.

Oldest human genome from southern Spain      (via sciencedaily.com) 

A new study reports on genomic data from a 23,000-year-old individual who lived in what was probably the warmest place of Europe at the peak of the last Ice Age. The oldest human genome recovered from the southern tip of Spain adds an important piece of the puzzle to the genetic history of Europe.

Mysterious new behavior seen in whales may be recorded in ancient manuscripts      (via sciencedaily.com) 

In 2011, scientists recorded a previously unknown feeding strategy in whales around the world. Now, researchers in Australia think they may have found evidence of this behaviour being described in ancient accounts of sea creatures, recorded more than 2,000 years ago. They believe that misunderstandings of these descriptions contributed to myths about medieval sea monsters. Whales are known lunge at their prey when feeding, but recently whales have been spotted at the surface of the water with their jaws open at right angles, waiting for shoals of fish to swim into their mouths. A clip of this strategy was captured in 2021 and went viral on Instagram. This strategy seems to work for the whales because the fish think they have found a place to shelter from predators, not realising they are swimming into danger. It's not known why this strategy has only recently been identified, but scientists speculate that it's a result of changing environmental conditions -- or that whales are being more closely monitored than ever before by drones and other modern technologies.
