A new genus and species of eutherian mammal has been described from a handful of tiny teeth found in the Prince Creek Formation in northern Alaska, the...
New paleoclimate evidence shows that around 1.1 million years ago, the southern European climate cooled significantly and caused an extinction of archaic...
New observations of mud cracks made by NASA’s Curiosity rover show that high-frequency, wet-dry cycling occurred in early Martian surface environments,...
Some steep slopes on Mars have gullies with morphologies suggesting that they were formed by a liquid. However, the planet’s current climate is not conducive...
Glacial cycles during the Early Pleistocene epoch are characterized by a dominant 41,000-year periodicity and amplitudes smaller than those of glacial...
Early humans and their hominin relatives had to adapt to new environments to spread out of Africa. In a new study, paleoanthropologists from the Institute...
In new research, scientists from the University of Cambridge and elsewhere reconstructed changes in summer and winter rainfall from trace elements and...
With ongoing carbon dioxide emissions from the burning of fossil fuels, the atmosphere of Earth heats up, which has dramatic consequences for the ice sheets....
Rocky exoplanets orbiting red dwarf (M-dwarf) stars are among the most promising and abundant astronomical targets for detecting habitable climates. Planets...
The Hittites were one of the great powers in the ancient world across almost five centuries, between 1650 and 1200 BCE, with an empire centered in Anatolia...
Paleontologists have described two new species of the early primatomorphan genus Ignacius from Ellesmere Island, Nunavut, Canada.
Life reconstruction of...
Researchers have analyzed microscopic fragments of 2-million-year-old environmental DNA from of the Kap København Formation in Greenland. The DNA record...
In addition to the discovery of Mbiresaurus raathi, Africa’s oldest known dinosaur species, Yale University paleontologist Christopher Griffin and his...
Detailed, well-dated palaeoclimate and archaeological records are critical for understanding the impact of environmental change on human evolution. In...
Mayapan emerged as a regional Maya capital on the Yucatán Peninsula, following the demise of Chichen Itza between 1000 and 1100 CE.
Drought may have...
University of Toronto astronomer Evelyn Macdonald and her colleagues have identified substantial differences in surface temperature, sea ice and water...
The 3,400-year-old settlement with a palace and several large buildings could be the ancient city of Zakhiku, believed to have been an important center...
Early Mars had rivers, but the cause of the transition from a wet planet to dry remains unknown. Past Martian climate can be probed using the distribution...
In a study published in the journal Frontiers in Ecology and Evolution, a team of scientists in South Africa assessed the effects of air temperature and...
