Why help another when you can help yourself? Cooperation is very common in nearly all life, from genes and cells to humans and other animals. However understanding why can be difficult: being selfish seems…
New research on invasive species has cast doubt on the prevailing theory developed by Charles Darwin, giving us a new way to predict and model species when they are introduced. Invasive animals such as…
On a TV show or in a movie, if a guy and a girl are at a party and one approaches the other to strike up a conversation, chances are that it was the guy who approached the girl. That is because we have…
We all know the story: Once upon a time there was a young girl who took a walk through the woods to visit her grandmother, carrying a basket of goodies. When she arrived she found her granny ill in bed…
Penguins are a remarkable group of flightless birds. We tend to think of them as Antarctic birds, but they actually inhabit an extremely diverse range of habitats from subzero Antarctic coastline to the…
A new study by Rebecca Pian, Mike Archer and Sue Hand, published today in the Journal of Vertebrate Paleontology, describes the tooth of a new, giant species of extinct platypus. The fossil history of…

Charles Darwin famously drew upon Thomas Malthus’s treatise on human population growth to build his theory of evolution by natural selection. Malthus was worried about the rising population of the lower…
The sudden appearance of a range of modern animals about half a billion years ago, during evolution’s “big bang”, has intrigued and puzzled generations of biologists from Charles Darwin onwards. A new…
The Silk Road snaked across continents for more than a thousand years, shaping civilisations in East and West. Famously trodden by Alexander the Great and Genghis Khan, the trade route brought riches to…
Ever since the Neandertal (Homo neanderthalensis) type fossil was discovered in the Neander Valley of Germany in 1856, the species has been variously portrayed as knuckle-dragging cavemen and primitive…
