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

A reduced genome in an island species raises evolutionary questions.

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

Evolutionary biology is the study of how life diversifies and adapts over time through a range of processes including mutation, genetic drift, gene flow, and natural selection. From its classical ...

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 ...

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

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 ...

A study in fruit flies suggests an internal genomic arms race may be driving rapid evolution in proteins that still perform an essential, unchanging job: protecting chromosome ends.

A new study by researchers at the Max Planck Institute for Evolutionary Biology (MPI-EB) sheds fresh light on one of the most debated concepts in biology: evolvability. The work provides the first ...

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 ...

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 ...

Human Evolutionary Biology lecturer Carole K. Hooven’s comments on a Fox News show last month maintaining the existence of two sexes and defending the usage of the terms “male” and “female” to refer ...
