Primate brain size does not predict their intelligence

Chimpanzees, gorillas and orangutans are our closest relatives, and like us they have relatively large brains and they are very intelligent. But do animals with larger brains really perform...

Organic chemical origins in hydrothermal systems

Serpentinite-hosted hydrothermal systems have been suggested as likely sites for the formation of organic compounds in the abiotic...

Mammals share mechanisms controlling the heart with a 400 million-year-old fish

Primitive air-breathing fish, whose direct ancestors first appeared around 400 million years ago, show mechanisms controlling the heart...

Replaying the tape of life: Is it possible?

How predictable is evolution? The answer has long been debated by biologists grappling with the extent to which...

Scientists discover how plants evolved to colonise land over 500 million years ago

Scientists analysing one of the largest genomic datasets of plants have discovered how the first plants on Earth...

You say tomato, these scientists say evolutionary mystery

Biologists at the University of Massachusetts Amherst have found evidence for evolutionary "syndromes" -- sets of traits that occur together -- that help to...

Pioneering research sheds surprising new light on evolution of plant kingdom

A new study has uncovered intriguing insights into the evolution of plant biology, effectively rewriting the history of how they evolved over the past...

Study illuminates mechanism that annotates genetic information passed from fathers to offspring

Van Andel Institute scientists and collaborators have identified a key part of a mechanism that annotates genetic information before it is passed from fathers...

Life on Earth didn’t arise as described in textbooks

No, oxygen didn't catalyze the swift blossoming of Earth's first multicellular organisms. The result defies a 70-year-old assumption about what caused an explosion of...

Genes for learning and memory are 650 million years old, study shows

A team of scientists led by researchers from the University of Leicester have discovered that the genes required for learning, memory, aggression and other...

‘Lava lamp’ vesicles show how cells could self-organize

The inside of a living cell is crowded with large, complex molecules. New research on how these molecules could spontaneously organize themselves could further...
