Ancient 2,500 BC Cycladic marble head lead Cottone's auction



An outstanding Cycladic marble head dating from 2,500 BC with impeccable provenance soared to $188,800

The Cycladic marble head, a prime example of the elegance achieved by Cycladic sculptors of the 3rd millennium BC, was easily the top-selling lot in an auction grossing around $2.6 million. These so-called Cycladic figurines or idols come from the homonymous Greek island chain in the Aegean Sea, where they were discovered in select graves. They almost certainly fulfilled a religious function that largely eludes us today, but probably involved fertility and rebirth as the figurines are often pregnant. In the early 20th century, artists such as Picasso, Modigliani, and Brancusi admired and were deeply influenced by the Cycladic aesthetic in their work... EIN News

Los seres humanos emigraron desde África hace 60.000 años debido a un cambio brusco del clima


 
Una nueva investigación paleoclimática demuestra que hace unos 70.000 años, el clima en el cuerno de África cambió de una fase húmeda llamada "Sáhara Verde", a unas condiciones más secas que las actuales, lo que provocó una migración de los primeros humanos

Jessica Tierney, profesora asociada de geociencias de la Universidad de Arizona y autora principal del estudio señala que: “siempre ha existido la pregunta de porqué los primeros seres humanos abandonaron África, y en este sentido, el clima siempre ha sido un factor de mucho peso a tener en cuenta en las hipótesis". Ahora nuestro estudio sugiere que cuando comenzó el éxodo de nuestra especie desde el continente africano hacía Eurasia, África era un lugar mucho más seco de lo que lo es en la actualidad”.

Ancient Humans Left Africa to Escape Drying Climate | UANews  
The search for greener pastures may have driven our ancestors to leave Africa for Eurasia.

Humans migrated out of Africa as the climate shifted from wet to very dry about 60,000 years ago, according to research led by a University of Arizona geoscientist.

Genetic research indicates people migrated from Africa into Eurasia between 55,000 and 70,000 years ago. Previous researchers suggested the climate must have been wetter than it is now for people to migrate to Eurasia by crossing the Horn of Africa and the Middle East...
