China's earliest modern human
04-02-2007 · EurekAlert!Researchers at Washington University in St. Louis and the Institute of Vertebrate Paleontology and Paleoanthropology in Beijing have been studying a 40,000-year-old early modern human skeleton found in China and have determined that the "out of Africa" dispersal of modern humans may not have been as simple as once thought.

- Researchers find earliest evidence for modern human behavior in South Africa
10-17-2007 · EurekAlert!
Evidence of early humans living on the coast in South Africa, harvesting food from the sea, employing complex bladelet tools and using red pigments in symbolic behavior 164,000 years ago, far earlier than previously documented, is being reported in the Oct. 18 issue of the journal Nature. The international team of researchers reporting the findings include Curtis Marean, a paleoanthropologist with the Institute of Human Origins at Arizona State University.

- Paleontologists discover most primitive primate skeleton
01-23-2007 · EurekAlert!
The earliest branches of primate evolution are more ancient by 10 million years than previous studies estimated, according to an article featured in the Proceedings of the National Academy of Sciences. Researchers reconstructed the base of the primate family tree by comparing skeletal and fossil specimens representing more than 85 modern and extinct species. The team also discovered two 56-million-year-old fossils, including the most primitive primate skeleton ever described.

- Genome study places modern humans in the evolutionary fast lane
12-10-2007 · EurekAlert!
Countering a common theory that human evolution has slowed to a crawl or even stopped in modern humans, a new study examining data from an international genomics project describes the past 40,000 years as a time of supercharged evolutionary change, driven by exponential population growth and cultural shifts.

- New findings solve human origins mystery
10-09-2007 · EurekAlert!
New research from Harvard University's Museum of Comparative Zoology and from the Cedars Sinai Institute for Spinal Disorders reveals evidence of the emergence of the upright human body plan over 15 million years earlier than most experts have believed. More dramatically, the study confirms preliminary evidence that many early hominoid apes were most likely upright bipedal walkers sharing the basic body form of modern humans. The study appears in PLoS ONE on Oct. 10.

- The 'MIP-MAP' game: Indian bug is the ancestor of Crohn's disease pathogen
10-02-2007 · EurekAlert!
An Indian team of researchers led by Seyed E. Hasnain of the Institute of Life Sciences, University of Hyderabad, India has found that a seemingly unknown mycobacterial organism Mycobacterium indicus pranii could be the earliest ancestor of the 'generalist' branch of mycobacterial pathogens. The 'generalist' bacteria infect anything from cockroaches to human and are capable of surviving in soil and water as against human adapted 'specialists' such as tubercle and leprosy bacilli.
