New research from the University of Lincoln, UK, is challenging a common assumption about the evolutionary origins of human ...

My colleague and I have published a new study of cactus flowers which may help explain the conundrum. For more than a century ...

Forget Survival Of The Fittest. Humans Conquered Our Planet By Sharing Ideas. In A Nutshell Humans spread across nearly every habitat on Earth in around 300,000 years, a feat that biology alone would ...

For decades, many evolutionary biologists argued that natural selection acts primarily on individuals. In other words, that organisms are rewarded or penalized one at a time, and that the idea of ...

Behind the stillness of desert landscapes, cacti appear to be changing in unexpected ways. The cactus on your windowsill may ...

Men have nipples, mammary glands and the hormones required, but the ability for male lactation rarely turns on. Here’s why ...

The study of early vertebrates provides an essential window into the evolutionary processes that shaped modern biodiversity. Fossil discoveries spanning the Silurian to Devonian periods reveal a ...

Evolutionary biology explores how living systems change over time through variation, inheritance and differential success. At its heart lies the concept of descent with modification: populations ...

The cactus on your windowsill may grow slowly, but new research shows that cacti are surprisingly fast at creating new ...

In Lake Malawi, hundreds of species of cichlid fish have evolved with astonishing speed, offering scientists a rare opportunity to study how biodiversity arises.

Scientists have developed a theoretical model that uncovers the dual role of polyploidy -- organisms carrying extra genome copies -- in evolution. Their findings reveal that polyploidy can stabilize ...
