We lie to ourselves all the time. We tell ourselves that we are better than average -- that we are more moral, more capable, less likely to become sick or suffer an accident.

By Ewen Callaway of Nature magazine A mutation that appeared more than half a million years ago may have helped humans learn the complex muscle movements that are critical to speech and language.

Foresters need to take a proactive approach to keeping their forests climate-ready, says the author of two studies on assisted migration in the forests of the Canadian province of Alberta.

As children settle into their classrooms for the beginning of a new school year, parents steel themselves for the pending battle. Mothers and fathers know well that their youngsters would rather pay attention to one another than to the blackboard. But parents may not realize that the reasons children struggle with education lie deep in our evolutionary past

More than 60 mammal species--like the famous flying squirrel--have adapted the ability to sail from tree to tree. Thrilling, yes

by Chloe McIver of Nature magazine Turtles should sit on the same branch of the tree of life as lizards, according to a genetic analysis that could clear up a long-standing mystery over the creature's origin. Palaeontologists have long used morphological data, obtained by looking closely at the physical characteristics of fossils and living relatives, to show the evolutionary relationship between different species.

In my most recent post a nd others --and in chats with George Johnson and Robert Wright on Bloggingheads.tv --I rail against biological determinism and defend free will.

NORMAN, Okla.-- Survival of the fittest really boils down to reproduction of the fittest. If an animal can survive long enough to pass on its genes to a new generation, it has won out in the evolutionary competition

A new augmented reality shopping platform for Xbox Kinect will allow users to try on clothes in true 3-D, share photos with friends, and store wish-listed items on smartphones for shopping on-the-go. Virtual reality shopping just got a lot more real--and could soon become a lot more mainstream.

MINNEAPOLIS--It’s a great irony of paleoanthropology that for all the insights scientists have been able to glean from the fossil record about our early ancestors, the australopithecines (Lucy and her kin), they have precious little to document the origin of our own genus, Homo. They know that Homo descended from one of those australopithecine species, and that over the course of that transition our ancestors evolved from chimp-size creatures with short legs and small brains into tall humans with long legs and large brains, among other hallmark traits

Creatures that live in the dark may lose their sight over evolutionary time. They may even lose their eyes entirely. Now it appears that they also lose sleep

Psychologists have long known that many people are prejudiced towards others based on group affiliations, be they racial, ethnic, religious, or even political. However, we know far less about why people are prone to prejudice in the first place
