Scientists shed light on Neanderthals’ legacy in humans

Scientists shed light on Neanderthals' legacy in humans

A new analysis of Neanderthal DNA showed today’s humans have more of it than scientists previously thought. A research published Thursday in the American Journal of Human Genetics found today’s humans probably have between 1.5 and 2.1 percent Neanderthal DNA from interbreeding across Europe and Asia between 130,000 and about 50,000 years ago. A female Neanderthal bone estimated to be ... Read More »

Global warming could let soil release more carbon into air, says new study

Global warming could let soil release more carbon into air, says new research

A new study suggests higher temperatures could release more carbon than we thought, potentially creating a dangerous feedback loop that would cause the planet to get hotter and hotter. The research, led by Jerry Melillo, distinguished scientist at the Marine Biological Laboratory, appears in the Oct. 6 issue of Science. Melillo and colleagues began this pioneering experiment in 1991 in ... Read More »

The study, reported in the journal Science, examined genetic information from the remains of anatomically modern humans who lived during the Upper Palaeolithic, a period when modern humans from Africa ...
