A major evolutionary theory says most genetic changes don’t really matter, but new evidence suggests that’s not true. Researchers found that helpful mutations happen surprisingly often. The twist is ...

The researchers think the pattern they observed in ants reflects a more universal trend in the evolution of societal ...

Some ants thrive by choosing numbers over strength. Instead of heavily protecting each worker, they invest fewer resources in ...

The origin of organisms with complex cells, known as eukaryotes, is one of the most crucial parts of life’s evolutionary story. All animals, plants, and fungi are eukaryotes, and if complex cells had ...

Would you rather fight a horse-sized duck or 100 duck-sized horses? The famous question, though implausible, reflects a ...

Humans have it. So does Drosophila. But not yeast. That "it" is a small pause at the start of gene activity—a brief molecular halt that may have helped life evolve from simple cells to complex animals ...

The discovery of a billion-year-old fossil in Scotland offers exciting new insight into animal evolution, BC researcher says Loch Torridon in Scotland, where the microfossil was discovered. Photo: ...

The tiny pantheon known as the Asgard archaea bear traits that hint at how plants, animals and fungi emerged on Earth.

Here’s a fun (and creepy) fact: The Earth is home to approximately 20 quadrillion ants. To put zeroes on it, that’s around 20,000,000,000,000,000 of the six-legged insects living all around us. How ...

Updated models suggest only 60,000 to 250,000 Earth-like habitats may exist in the Galaxy, with far fewer capable of ...
