AUSTIN, Texas — Lucy, the most famous fossil of a human ancestor, probably died after falling from a tree, according to a study appearing in Nature led by researchers at The University of Texas at Austin. (more…)

Classic arcade-inspired samurai game “Skulls of the Shogun” is available today for download play on Xbox 360, Windows Phone and Windows 8. Delving into the afterlife of a famous general, this is Microsoft’s first modern cross-platform game.
REDMOND, Wash. – Jan. 30, 2013 — With the new game “Skulls of the Shogun,” players can do something new: Switch back and forth between all of their Microsoft devices as they bounce from battle scene to battle scene.
The game, released today, is the first to reach all Microsoft platforms. “Skulls of the Shogun” can be downloaded and played on Xbox 360 via the Xbox LIVE Arcade, and on Windows Phone 8 and Windows 8 devices. (more…)
Researchers at Yale have identified an ancient slithering creature from the time of T. rex as the most primitive known snake, a finding with implications for the debate over snake origins.
“It’s the missing-link snake,” said Nicholas Longrich, a postdoctoral fellow in Yale’s Department of Geology & Geophysics and the lead author of a paper about the lizard-like snake published July 25 online in the journal Nature. “It’s the ‘Lucy’ of snakes.”
The paper argues that snakes descend from terrestrial rather than marine ancestors, as recently proposed by others, and that snakes emerged once lizards developed long, limbless bodies for burrowing. (more…)
*Discovery of partial foot skeleton could mean hominin species lived side by side*
A new fossil discovery from Eastern Africa called the Burtele foot indicates Australopithecus afarensis, an early relative of modern humans, may not have been the only hominin to walk the plains and woodlands of what is now the Afar region of Ethiopia some 3.4 million years ago.
Researchers openly have questioned whether Au. afarensis, the species to which the famous fossil “Lucy” belongs, was the only living hominin during the late Pliocene of Africa. Lucy’s bones provided evidence that she and perhaps other early hominins may have walked upright, but whether or not she was the sole hominin species in her particular geologic time scale has been the subject of much debate.

The males of two bipedal hominid species that roamed the South African savannah more than a million years ago were stay-at-home kind of guys when compared to the gadabout gals, says a new high-tech study led by the University of Colorado Boulder.
The team, which studied teeth from a group of extinct Australopithecus africanus and Paranthropus robustus individuals from two adjacent cave systems in South Africa, found more than half of the female teeth were from outside the local area, said CU-Boulder adjunct professor and lead study author Sandi Copeland. In contrast, only about 10 percent of the male hominid teeth were from elsewhere, suggesting they likely grew up and died in the same area. (more…)
Scientists seeking to understand the origin of the human mind may want to look to honeybees — not ancestral apes — for at least some of the answers, according to a University of Colorado Boulder archaeologist.
CU-Boulder Research Associate John Hoffecker said there is abundant fossil and archaeological evidence for the evolution of the human mind, including its unique power to create a potentially infinite variety of thoughts expressed in the form of sentences, art and technologies. He attributes the evolving power of the mind to the formation of what he calls the “super-brain,” or collective mind, an event that took place in Africa no later than 75,000 years ago. (more…)
*3.2 million-year-old human predecessor had arches in feet*
COLUMBIA, Mo. – Feet arches give humans a spring in their steps, shock absorbing abilities, and stiff platforms to propel themselves forward, allowing them to walk upright consistently. Now, researchers at the University of Missouri and Arizona State University have found proof that arches existed in a predecessor to the human species that lived more than 3 million years ago. This discovery could change scientists’ views of human evolution. The study is being published this week in Science.
Carol Ward, an MU researcher in the Department of Pathology and Anatomical Sciences at the MU School of Medicine, and William Kimbel and Donald Johanson, director and founding director of the Institute of Human Origins at Arizona State University, studied a 3.2 million-year-old fourth metatarsal of Australopithecus afarensis. A team from the Institute of Human Origins and National Museum of Ethiopia led by Kimbel discovered the fossil in Hadar, Ethiopia. The species is often referred to as “Lucy,” the nickname of the most complete fossil skeleton of the species to be discovered. (more…)
