La revista Science ha sacado su lista de todos los meses de diciembre en la que se da cuenta de cuáles han sido...

... Pero figura en segundo lugar el método de recuperación de DNA antiguo a partir de los restos fósiles que ha permitido obtener el código genético casi completo de un ancestro humano procedente de Denisova -montañas Altai, sudoeste de Siberia- que vivió hace más de 70.000 años. Matthias Meyer, investigador postdoc del instituto Max Planck de Antropología en Leipzig (Alemania), fue quien imaginó y puso a punto la técnica. [...] CAMILO JOSÉ CELA CONDE / diariodemallorca.es/

American journalist to spend next 7 years walking to retrace humankind’s origins

In the context of the modern news cycle, American journalist Paul Salopek’s plan to spend seven years walking across the world gathering stories is radically slow.

In the context of human evolutionary history, his journey is running at warp-speed. Salopek’s route — moving from Ethiopia into Israel, continuing across Eurasia, and finishing at the very tip of South America — retreads the path our earliest ancestors took as they radiated out of the “cradle of humankind” and into new continents, a process that began 60,000 years ago.

Both contexts are necessary to understand Salopek’s “Out of Eden” walk, which begins in January. [...] thestar.com/

Reindeer have been revered and hunted by man for tens of thousands of years. They are a living, breathing connection to a lost world

... The end of the ice age saw a massive global extinction: many large mammals fell prey to changing climate and the effect of some rather formidable hunters sharing their landscape. There was a decline in the genetic diversity of reindeer after the peak of the last ice age 20,000 years ago – probably due to a warming climate as well as those palaeolithic hunters – but reindeer survived, and thankfully they don't look likely to become extinct any time soon.

"Decoding Neanderthals" to be broadcast

NOVA on American PBS stations has produced a new documentary about Neandertals: "Decoding Neanderthals". They have just announced that it will be broadcast January 9 on most stations.
Here's the program description:
Over 60,000 years ago, the first modern humans—people physically identical to us today—left their African homeland and entered Europe, then a bleak and inhospitable continent in the grip of the Ice Age. But when they arrived, they were not alone: the stocky, powerfully built Neanderthals had already been living there for hundred of thousands of years. So what happened when the first modern humans encountered the Neanderthals? Did we make love or war? That question has tantalized generations of scholars and ...
I make an appearance on the show -- and that's my voice in the trailer talking about the "mother of all public relations problems" that Neandertals have faced. [...] John Hawks
