Biologists are closing in on a puzzle that seems to turn classic evolutionary logic inside out, yet may be so common that it ...

It may have fewer than many of the other sciences, but biology does have two dozen or so “rules”—broad generalizations about ...

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 ...

Environmental change doesn’t affect evolution in a single, predictable way. In large-scale computer simulations, scientists ...

Other than a few species of whale, humans are the only mammals that consistently demonstrate the unusual phenomenon of menopause. Most animals maintain their reproductive ability for the vast majority ...

Katie has a PhD in maths, specializing in the intersection of dynamical systems and number theory. She reports on topics from maths and history to society and animals. Katie has a PhD in maths, ...

Are bears getting soft on us? After centuries of living in close proximity with people, a population of brown bears has ...

The most comprehensive dataset of termite genomes to date was created by an international team of scientists, led by ...

The study of Astyanax mexicanus, encompassing both its cave-adapted and surface-dwelling forms, has emerged as a model for understanding evolutionary adaptation to extreme environments. Researchers ...

Walk into consciousness labs, and you will mostly find studies on humans relying on verbal reports. This evidence is then ...

Erik Svensson receives funding from from the Swedish Research Council (VR; grant no. 2020-03123). How will life on Earth and the ecosystems that support it adapt to climate change? Which species will ...

Mutation: it’s the raw material for evolution. That makes knowing the rate at which it occurs crucial to the study of evolutionary biology. Mutation rate figures into all kinds of calculations. For ...
