In the East Siberian Arctic (>70 °N), there is not only evidence of significant woolly mammoth populations, but also how humans interacted with them, the focus of new research in Quaternary Science Reviews.

Elephants call out to each other using individual names that they invent for their fellow pachyderms, a study said on Monday.

Earth’s largest remaining tract of tropical rainforest is kept alive by a complex water cycle that we’re only just beginning to understand. Yet our activities are changing it before we can see the full picture, a new report finds.

New research led by geologists at Western Australia’s Curtin University provides evidence that fresh water emerged on Earth about 4 billion years ago – half a billion years earlier than previously thought. The study is published in the journal Nature Geoscience.

Researchers have explored how the River Nile evolved over the past 11,500 years and how changes in its geography could have helped shape the fortunes of ancient Egyptian civilisation. The research is published in Nature Geoscience.

New research published in the journal Science Advances might explain the Earth-shaking processes that led to the end-Cambrian mass extinction.

Despite decades of study, this Ice Age mystery remains unsolved. Researchers simply don’t have sufficient evidence at this point to rule out one scenario or the other—or indeed other explanations that have been proposed (e.g. disease, an impact event from a comet, or a combination of factors)… A new work published in Frontiers in Mammal Science set out to address this information deficit.

A new study of stick insects suggests that evolution may sometimes repeat itself in a predictable manner, which could help our understanding of how organisms may change in response to selection pressures. The study has been published in Science Advances.

A 7,000-year-old Neolithic settlement in modern-day Greece has, for the first time, been accurately dated down to the precise years it was built. The findings could provide a reference point in time to help date other archaeological sites in southeastern Europe. Their research is published in the journal Nature Communications.

The findings contribute to the growing body of research around Traditional Ecological Knowledge and practices, demonstrating the care and specificity with which Indigenous groups have been stewarding and cultivating natural resources for millennia. The work is published in The Holocene journal.

The iconic, “upside-down” baobab tree first emerged on the island of Madagascar, new research into its tangled evolutionary history reveals. It’s still not clear, however, how it jumped from Madagascar to Australia. See the new study, which was published Wednesday (May 15) in the journal Nature.

The first dinosaurs to have a warm-blooded metabolism might have emerged 180 million years ago during the early Jurassic period, according to a new study. New research published in the journal Current Biology might have answered that question.

Is Stonehenge aligned with the moon? Scientists hope to find out during a rare ‘major lunar standstill, which happens once every 18.6 years.

Around 6,200 BCE, the climate changed. Previously, archaeologists believed that this abrupt shift in global climate, called the 8.2ka event, may have led to the widespread abandonment of coastal settlements in the southern Levant. In a recent study published in the journal Antiquity, researchers…share new evidence suggesting at least one village formerly thought abandoned not only remained occupied, but thrived throughout this period.

A new study, led by the University of Oxford and MIT, has recovered a 3.7-billion-year-old record of Earth’s magnetic field and found that it appears remarkably similar to the field surrounding Earth today. The findings have been published in the Journal of Geophysical Research. Without its magnetic field, life on Earth would not be possible…

In the darkest corners of the planet, where the light of the Sun never touches, eerie glows can yet be found, illuminating the shadows. This is bioluminescence, a remarkable ability that has evolved separately at least 94 times throughout the history of life on Earth. See the study here.
