Man's earliest direct ancestors looked more apelike than previously believed
03-24-2007 · EurekAlert!A computer-generated reconstruction by NYU College of Dentistry Professor Dr. Timothy Bromage, shows a 1.9 million-year-old skull belonging to Homo rudolfensis with a surprisingly small brain and distinctly protruding jaw. Dr. Bromage's is the first scientist to produce a reconstruction of the skull that questions Richard Leakey's depiction of modern man's earliest direct ancestor as having a vertical facial profile and a relatively large brain -- an interpretation widely accepted until now.

- HIV's path out of Africa: Haiti, the US then the world
10-29-2007 · EurekAlert!
The AIDS virus entered the United States via Haiti, probably arriving in just one person in about 1969, earlier than previously believed, according to new research. The research is the first to definitively pinpoint when and from where HIV-1 entered the United States, and shows that most HIV/AIDS viruses in the US descended from a single common ancestor.

- Human ancestors more primitive that once thought
09-20-2007 · EurekAlert!
A team of researchers, including Herman Pontzer, Ph.D., assistant professor of physical anthropology at Washington University in St. Louis, has determined through analysis of the earliest known hominid fossils outside of Africa, recently discovered in Dmanisi, Georgia, the former Soviet republic, that the first human ancestors to inhabit Eurasia were more primitive than previously thought.

- Varied diet of early hominid casts doubt on extinction theory, says Colorado U. study
11-09-2006 · EurekAlert!
An upright hominid that lived side by side with direct ancestors of modern humans more than a million years ago had a far more diverse diet than once believed, clouding the notion that it was driven to extinction by its picky eating habits as the African continent dried, says a new University of Colorado at Boulder study.

- Study sheds light on why humans walk on two legs
07-23-2007 · EurekAlert!
Studying chimpanzees trained to use treadmills, a team of anthropologists have gathered new evidence suggesting that our earliest apelike ancestors started walking on two legs because it required less energy than getting around on all fours.

- Clues to future evolution of HIV come from African green monkeys
07-16-2007 · EurekAlert!
Monkey viruses related to HIV may have swept across Africa more recently than previously thought, according to research from the University of Arizona in Tucson. A new family tree for African green monkeys shows that simian immunodeficiency virus first infected those monkeys after the lineage split into four species. The new research reveals the split happened about 3 million years ago. Scientists had thought SIV infected an ancestor of green monkeys before the speciation event.

- Wolves are suffering less from inbreeding than expected
12-20-2006 · EurekAlert!
Increasing levels of inbreeding is a threat against the viability of the Scandinavian wolf population. A study just coming out in the new journal PLoS ONE now demonstrates that inbreeding is not affecting the wolves as badly as expected. The results show that it is the most genetically variable wolf individuals that are recruited into the breeding population. An important consequence of this action of natural selection is that the negative effects of inbreeding are accumulating much slower than previously believed.

- Animal behavior study overturned
10-24-2007 · EurekAlert!
An international team of scientists has overturned an ecological study on how some animals search for food. Previously it was believed that wandering albatrosses and other species forage using a Levy flight strategy -- a cluster of short moves connected by infrequent longer ones. Published this week in the journal Nature, the team discovered that further analyses and new data tell a different story for the albatrosses and possibly for other species too.

- Newly discovered active fault building new Dalmatian Islands off Croatian coast
01-22-2008 · EurekAlert!
A newly identified fault that runs under the Adriatic Sea is actively building more of the famously beautiful Dalmatian Islands and Dinaride Mountains of Croatia, according to a new research report. Geologists had previously believed that the Dalmatian Islands and the Dinaride Mountains had stopped growing 20 to 30 million years ago. The Croatian coast is an increasing popular tourist destination. Dubrovnik, known as "the Pearl of the Adriatic," is a UNESCO-designated World Heritage site.

- Mutant sperm guide clinicians to new diseases
12-02-2007 · EurekAlert!
New research published in Nature Genetics shows that some rearrangements of the human genome occur more frequently than previously thought. The work is likely to lead to new identification of genes involved in disease and to improve diagnosis of genomic disease. Researchers from the Wellcome Trust Sanger Institute looked at four regions in the genome where rearrangements cause so-called "genomic disorders," and found that some rearrangements were found in sperm much more frequently than expected.
