Ancient New Zealander Genome Sequenced
2012-10-23 21:08:06

April Flowers for redOrbit.com — Your University Online A research team from the University of Otago has achieved landmark results by sequencing the complete mitochondrial genome for members of what was likely to be one of the first groups of Polynesians to settle New Zealand. The results of this study, published online in the Proceedings of the National Academy of Sciences, have revealed a surprising degree of genetic variation among these pioneering voyagers. Similar DNA...

Image 1 - Were European Neanderthals Long Gone Before Humans Arrived?

New research suggests Western European Neanderthals were likely to have been extinct long before humans arrived on the evolutionary scene. Long thought to be the birth place of Neanderthal evolution, Western Europe has been studied and researched by scientists and anthropologists to better understand our ancient forefathers. As these Neanderthals began to disappear around 30,000 years ago, anthropologists had estimated either climate changes or competition from early humans caused the...

European Neanderthals We Already Close To Extinction Before Arrival Of Modern Humans

New findings from an international team of researchers show that most Neanderthals in Europe died off around 50,000 years ago. The previously held view of a Europe populated by a stable Neanderthal population for hundreds of thousands of years up until modern humans arrived must therefore be revised. This new perspective on the Neanderthals comes from a study of ancient DNA published Feb 25 in Molecular Biology and Evolution. The results indicate that most Neanderthals in Europe died off...

An international team of scientists, including researchers from Murdoch University, have just published findings that re-interpret the history of our species' original dispersals across the planet. Using a piece of hair donated by a West Australian Aboriginal man around 100 years ago, the team sequenced an individual's entire DNA code (or genome) to prove that multiple dispersals of early humans populated the world, contrary to the commonly-held single dispersal theory. Perth, Western...

Evolution's Past Is Modern Human's Present

  Mandenka, Biaka and San tested for DNA evidence of ancient interbreeding inside Africa The past is present when it comes to human evolution. That seems to be the takeaway from new research that concludes "archaic" humans, somewhere in Africa during the last 20-60 thousand years, interbred with anatomically modern humans and transferred small amounts of genetic material to their offspring who are alive today. University of Arizona geneticist Michael Hammer and a team of...

Antibiotic Resistance Found In Ancient DNA
2011-09-05 04:33:02

  A team comprised primarily of Canadian researchers has discovered antibiotic resistance in the DNA of 30,000-year-old bacteria found in the Yukon permafrost, various media outlets reported last week. The scientists, who published their findings in the journal Nature, note that resistant microbes are commonly thought to have developed after the development of synthetic antibiotics over 70 years ago. However, they discovered that it is not a "modern phenomenon," but is in fact "a...

Scientists were surprised at how fast bacteria developed resistance to the miracle antibiotic drugs when they were developed less than a century ago. Now scientists at McMaster University have found that resistance has been around for at least 30,000 years. Research findings published today in the science journal Nature show antibiotic resistance is a natural phenomenon that predates the modern clinical antibiotic use. Principal investigators for the study are Gerry Wright, scientific...
