Neanderthal genes give clues to human brain evolution

A distinctive feature of modern humans is our round (globular) skulls and brains. On December 13, in the journal Current Biology, researchers report that present-day humans who carry particular Neanderthal DNA fragments have heads that are slightly less rounded, revealing genetic clues to the evolution of modern brain shape and ...

Tiny fossils unlock clues to Earth’s climate half a billion years ago

An international collaboration of scientists, led by the University of Leicester, has investigated Earth’s climate over half a billion years ago by combining climate models and chemical analyses of fossil shells about 1mm long. The research, published in Science Advances, suggests that early animals diversified within a climate similar to ...

Mars study yields clues to possible cradle of life

The discovery of evidence for ancient sea-floor hydrothermal deposits on Mars identifies an area on the planet that may offer clues about the origin of life on Earth. A recent international report examines observations by NASA’s Mars Reconnaissance Orbiter (MRO) of massive deposits in a basin on southern Mars. The ...

Newly discovered brain network offers clues to social cognition

Scientists call our ability to understand another person’s thoughts — to intuit their desires, read their intentions, and predict their behavior — theory of mind. It’s an essential human trait, one that is crucial to effective social interaction. But where did it come from? Working with rhesus macaque monkeys, researchers ...
