Investigadores de la Universidad de Stanford y la UCLA han cultivado en laboratorio una suerte de ‘minicerebros’ capaces de madurar de forma muy parecida a las primeras etapas de vida del cerebro de los bebés. Para conseguirlo, los autores del estudio …
Using radiocarbon dating of 27 mud wasp nests, collected from more and less than 16 similar paintings, it has been confirmed that the rock art depicting the kangaroo that you can see at the head of this entry is the oldest art found in Australia.
According to him study that details it, published in Nature Human Behavior, and carried out by researchers from the University of Melbourne, is has placed the painting between 17,100 and 17,500 years ago.
The kangaroo is painted on the sloping roof of a rock shelter on the Unghango clan estate in Balanggarra Country, above the Drysdale River in the north-eastern Kimberley region of Western Australia. As explained by the postdoctoral researcher Dr. Damien Finch, who pioneered the exciting new radiocarbon technique:
We will never be able to know what was on the artist's mind when he painted this work more than 600 generations ago, but we do know that the naturalistic period dates back to the Last Ice Age, so the environment was cooler and drier than today.
The next step for researchers is to date more wasp nests in contact with this and other styles of Kimberley rock art to establish, more precisely, when each artistic period developed when it began and when it ended.
