Europeans did not inherit pale skins from Neanderthals

09-26-12. The people who built Stonehenge 5000 years ago probably had the same pallid complexion of many modern inhabitants of the UK. Now it seems that the humans occupying Britain and mainland Europe only lost the darker skins of their African ancestors perhaps just 6000 years earlier, long after Neanderthals had died out. The finding confirms that modern Europeans didn't gain their pale skin from Neanderthals – adding to evidence suggesting that European Homo sapiens and Neanderthals generally kept their relationships strictly platonic.

There is a clear correlation between latitude and skin pigmentation: peoples that have spent an extended period of time at higher latitudes have adapted to those conditions by losing the skin pigmentation that is common at lower latitudes, says Sandra Beleza at the University of Porto in Portugal. Lighter skin can generate more vitamin D from sunlight than darker skin, making the adaptation an important one for humans who wandered away from equatorial regions.

Those wanderings took modern humans into Europe around 45,000 years ago – but exactly when the European skin adapted to local conditions had been unclear [...] New Scientist

Actualización 05-10-12. Los europeos no heredaron su pálida piel de los neandertales
01-10-12. La gente que construyó Stonehenge hace 5000 años probablemente tenía la misma tez pálida que muchos habitantes modernos del Reino Unido. Ahora parece que los seres humanos que ocupan Gran Bretaña y Europa continental sólo perdieron las pieles más oscuras de sus ancestros africanos tal vez tan sólo 6000 años antes, y eso es mucho después de que los neandertales hubieran desaparecido. El hallazgo confirma que los europeos modernos no ganaron su pálida piel de los neandertales, algo que se añade a las evidencias que sugieren que el Homo sapiens y los neandertales europeos, en general, mantuvieron unas relaciones estrictamente platónicas...
