First molars provide insight into evolution of great apes, humans
The timing of molar emergence and its relation to growth and reproduction in apes is being reported by two scientists at Arizona State University's Institute of Human Origins
Lithic Assemblage Dated to 1.57 Million Years Found at Lézignan-la-Cébe, Southern France « Anthropology.net
Physorg are reporting an exciting find of what are described as 30 ‘pebble culture’ lithic tools, dating back over 1.5 million years, at a site which has been dated argon dated to 1.57 million years old, thanks to an ancient volcanic eruption whose lava flow preserved the ancient ground surfaces.
French find puts humans in Europe 200,000 years earlier
Experts on prehistoric man are rethinking their dates after a find in a southern French valley suggested our ancestors may have reached Europe 1.57 million years ago: 200,000 years earlier than we thought.
On the Origin of the Future
As the world celebrates the 150th anniversary of the publication of On the Origin of Species this year, scientists continue to think deeply about what comes next. But the complexity of evolution still makes forecasting hard. "As Yogi Berra once said, ‘Prediction is very difficult. Especially about the future,’" says Stephen Stearns, an evolutionary biologist at Yale University. (Carl Zimmer)

A background mutation rate guarantees this process. Each baby's DNA carries about 130 new mutations.

xactly which mutations natural selection will favor, however, depends on the environment in which we live. And over the past 10,000 years, we humans have dramatically changed that environment.

3-D Renderings Bring Ancient Hominids to Life | Wired.com
Computers allow a level of detail and control that isn’t possible with other media. Their creations can come closer than ever to bringing our ancestors to life.
Humans Still Evolving as Our Brains Shrink | LiveScience
Evolution in humans is commonly thought to have essentially stopped in recent times. But there are plenty of examples that the human race is still evolving, including our brains, and there are even signs that our evolution may be accelerating.
Top 10 Mysteries of the First Humans | LiveScience
Humans are unique among life on this planet, and much remains a mystery as to how we evolved. What steps came first? Why did we evolve this way and not that direction? Why are we the only human species left? What other paths might we have gone down in our evolution? And what directions might we go from here?
Top 10 Things that Make Humans Special | LiveScience
Humans are unusual animals by any stretch of the imagination, ones that have changed the face of the world around us. What makes us so special when compared to the rest of the animal kingdom? Some things we take completely for granted might surprise you.
Human Evolution: Our Closest Living Relatives, the Chimps | LiveScience
As scientists try and solve and mystery of how we originated, an invaluable source of clues is the chimpanzee.
Sharpening the Focus On Human Evolution
The identification of "Ardi" is a major breakthrough because her species was an early step in the process of human evolution. Scientists do not claim to know whether that Ardi's species evolved directly into modern humans, but it is an important branch on the family tree.

The Mysterious Downfall of the Neandertals
Scientists have long debated what led to their disappearance. The latest extinction theories focus on climate change and subtle differences in behavior and biology that might have given modern humans an advantage over the Neandertals. (Scientific American)
What Makes Us Human?
Comparisons of the genomes of humans and chimpanzees are revealing those rare stretches of DNA that are ours alone.
The Big Similarities & Quirky Differences Between Our Left and Right Brains
On the day I visited, there were half a dozen brains sitting on a table. Vonsattel began by passing them around so the medical students could take a closer look. When a brain came my way, I cradled it and found myself puzzling over its mirror symmetry. It was as if someone had glued two smaller brains together to make a bigger one. (Carl Zimmer)
How similar was Neandertal behavior to that of modern humans?
The results of a new study presented here last week at the annual meeting of the Paleoanthropology Society bolster that view, and suggest that, in fact, Neandertals acted in much the same way as early modern humans. (Scientific American Blog)
