Neanderthals And Humans - Interbreeding Or Common Ancestry
2012-08-14 07:51:50

April Flowers for redOrbit.com - Your Universe Online A new study from the University of Cambridge finds that the DNA similarities between Neanderthals and modern humans are more likely to have arisen from a shared common ancestor than from interbreeding. Previously, it has been suggested that the shared parts of the genome sequence between the two populations was the result of interbreeding, but the new research, published this week in the journal Proceedings of the National Academy of...

redOrbit Staff & Wire Reports - Your Universe Online The largest survey of Native American DNA ever conducted has revealed that people settled the New World in three distinct waves, not one as previously believed, various media outlets reported Wednesday. According to Robert Lee Hotz of the Wall Street Journal, Harvard Medical School Geneticist David Reich and an international team of colleagues compared thousands of genetic variations among 52 contemporary Native American...

More than just a tool for predicting health, modern genetics is upending long-held assumptions about who we are. A new study by Harvard researchers casts new light on the intermingling and migration of European, Middle Eastern and African and populations since ancient times. In a paper titled "The History of African Gene Flow into Southern Europeans, Levantines and Jews," published in PLoS Genetics, HMS Associate Professor of Genetics David Reich and his colleagues investigated the proportion...

Scientists have recovered the DNA code of a human relative discovered recently in Siberia, which found that the relative roamed far from the cave that holds its only known remains. Scientists found evidence that these "Denisovans" from over 30,000 years ago ranged all across Asia.  They apparently interbred with the ancestors of people that now live in Melanesia. There is no sign that Denisovans mingled with ancestors of people living in Eurasia, which made the connection between...

NEW YORK, Oct. 29 /PRNewswire/ -- When clocks go back an hour early Sunday morning, our roads and highways may become more dangerous as people drive drowsy, according to The National Road Safety Foundation, Inc. (NRSF), a non-profit group that offers free driver safety programs. Drowsy driving is a significant factor in traffic crashes. The risk increases as daylight savings time ends and we spend more time driving at night, says David Reich of NRSF. "Drowsy driving is as dangerous as...

Many teens heading back to school are sleep deprived as they drive to and from school, increasing their accident risk, U.S. researchers say. David Reich, spokesman for the National Road Safety Foundation, says drowsy driving is a risky behavior common among young drivers. The National Highway Traffic Safety Administration estimates more than 100,000 crashes every year are due to driver fatigue, resulting in more than 1,500 deaths and 71,000 injuries. Reich says there are several signs that...

NEW YORK, Sept. 3 /PRNewswire/ -- As millions of teens head back to school, many will be driving to and from classes every day. Teens are at a greater risk of than any other age group to be involved in a crash, due largely to lack of experience. Many of those crashes could be avoided with proper education, says The National Road Safety Foundation (NRSF), a non-profit group that produces free driver education programs. NRSF spokesperson David Reich said common mistakes by new drivers...

LONDON (Reuters) - Humans' evolutionary split from their closest relatives, chimpanzees, may have been more complicated, taken longer and probably occurred more recently than previously thought, scientists said on Wednesday. After comparing the genomes, or genetic codes, of the two species they suggest the initial split took place no more than 6.3 million years ago and probably less than 5.4 million years ago. The process of separation may have taken about 4 million years and there...
