Bronze Age natural selection accelerated human evolution, challenging long-held beliefs about genetic adaptation.

For most of human history, green eyes didn’t exist. Understanding why they do now means rethinking what we know about ...

Galápagos plants show repeated evolution and emerging species, emphasizing evolution’s flexibility and active role today.

Human aging is not what natural selection failed to prevent. It is what happens when selection simply has nothing left to act on.

Some researchers hold that evolution hasn’t much altered humans in the past 10,000 years. A new analysis of ancient DNA indicates that natural selection continued to shape hundreds of genes. By Carl ...

When our distant ancestors first traded nomadic life for farming, villages, and permanent homes, you might assume that the beastly forces of natural selection lost their ability to shape our species, ...

A genetic “cheat sheet” allows different species to display the same warning patterns.

Poison frogs appear to have built their chemical defenses gradually: related frogs store low to moderate levels of ...

A massive study of ancient DNA from nearly 16,000 people across more than 10,000 years in West Eurasia reveals that natural selection has shaped modern human genomes far more than previously thought.
