'Genetic time machine' reveals complex chimpanzee cultures

In recent decades, scientists have clearly demonstrated that chimpanzees, like humans, pass on complex cultures such as tool use from generation to generation. But human culture has become vastly more sophisticated, from ...

How humans evolved to be 'energetically unique'

Humans, it turns out, possess much higher metabolic rates than other mammals, including our close relatives, apes and chimpanzees, finds a Harvard study. Having both high resting and active metabolism, researchers say, enabled ...

How brain evolution is linked to the use of tools

Researchers led by Dr. Alexandros Karakostis from the Institute for Archaeological Science and the Senckenberg Center for Human Evolution and Palaeoenvironment at the University of Tübingen suggest that changes in the brain ...

New fossil reveals the evolution of flying reptiles

The pterosaurs are extinct flying reptiles that lived alongside their close relatives, the dinosaurs. The largest of these reached 10 m in wingspan, but early forms were generally limited to around 2 m. In a paper, a team ...

3D virtual skulls study maps missing piece of brain evolution

The temporal lobe—a key area of our brain responsible for our memory and communication—could also reveal hidden clues about how human brains have evolved over time, according to a new study from The Australian National ...

Research team discovers 'impossible' unicellular organism

The origin of eukaryotes is considered one of the greatest enigmas in biology: according to current doctrine, two prokaryotes, a so-called Asgard archaeon and a bacterium, are believed to have merged. The bacterium is said ...

Exploring Darwin's longstanding interest in biological rhythms

A close reading of Darwin's work suggests a deep interest in cyclical events. Rhythmic phenomena in nature—today the subjects of the field of chronobiology—have been studied since at least the 18th century. In a perspective, ...
