Modern microbes provide window into ancient ocean — ScienceDaily

Step into your new, microscopic time machine. Scientists at the University of Colorado Boulder have discovered that a type of single-celled organism living in modern-day oceans may have a lot in common with life forms that existed billions of years ago — and that fundamentally transformed the planet. The new research, which will appear Jan. […]

How is Modern Climate Change Affecting Landscape Processes?

Over the past 50 years human alteration of Earth’s climate has accelerated rapidly, which will inevitably affect physical landscape processes in societally challenging ways. But landscape responses to modern climate change have not been synthesized previously over any large regional scale. A recent article in Reviews of Geophysics explores anticipated landscape consequences of […]

A Little-Known Mass Extinction and the “Dawn of the Modern World”

Massive volcanic eruptions followed by climate change, widespread extinction, and, eventually, the emergence of new life forms. It sounds like the story of one of Earth’s five great mass extinctions. Now researchers say the same description applies to a lesser known—but highly consequential—event referred to as the Carnian Pluvial Episode (CPE), 233 million […]

Finding Prehistoric Rain Forests by Studying Modern Mammals

The Amazon rain forest is one of the most biodiverse places on Earth and plays a key role in the planet’s carbon and oxygen cycles. Despite its global importance, many aspects of this ecosystem’s history are still a mystery. Julia Tejada, who recently received her Ph.D. from Columbia University’s Lamont-Doherty Earth Observatory and […]

Neanderthal children grew and were weaned similarly to modern humans

3D Reconstruction Of The Three Neanderthal Milk Teeth Analyzed. Credit: Federico Lugli Neanderthals behaved similarly to modern humans in raising their children, whose pace of growth was similar to Homo sapiens. Thanks to the combination of geochemical and histological analyzes of three Neanderthal milk teeth, researchers were able to determine their pace of growth and […]

Modern humans took detours on their way to Europe — ScienceDaily

Favourable climatic conditions influenced the sequence of settlement movements of Homo sapiens in the Levant on their way from Africa to Europe. In a first step, modern humans settled along the coast of the Mediterranean Sea. Only then did they spread out into the Sinai desert and the eastern Jordanian Rift Valley. This is the […]
