Las huellas del México prehistórico, en serie documental



... México en la Edad de Hielo, que la televisora pública estrenará durante el primer trimestre de este año, narra historias en torno a la megafauna que habitó nuestro territorio, las batallas que libraron para sobrevivir; revela información sobre las investigaciones que se llevan a cabo en diversos sitios paleontológicos y arqueológicos, y aborda las diferentes teorías sobre la extinción de esas especies que vivieron durante la llamada Edad de Hielo, que se inició hace unos 110 mil años y terminó hace unos 10 mil años.

La serie, realizada por el documentalista mexicano Fabricio Feduchy, emplea innovadoras técnicas de animación en 3D que permite recrear los paisajes y las especies de esa era. La producción ha contado con la colaboración del paleoescultor y artista digital Sergio de la Rosa, conocido por sus dibujos prehistóricos.

The first known Chinese kingdom may have been destroyed when its lands rapidly transformed into deserts, possibly driving its people into the rest of China, a new study finds.

This new finding suggests that the kingdom may have been more important to Chinese civilization than experts had thought, researchers say.

Prior research suggests the earliest Chinese kingdom might have been Hongshan, established about 6,500 years ago. This was about 2,400 years before the supposed rise of the Xia Dynasty, the first dynasty in China described in ancient historical chronicles. The kingdom's name, which means "Red Mountain," comes from the name of a site in the Inner Mongolia region of China. [...] livescience.com

Chimpanzees select nut-cracking tools taking account of up to five different factors

Are chimpanzees sensitive to the effect of an object's properties on nut-cracking efficiency and plan their tool selection accordingly? An international team of researchers of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, has now investigated the selection of hammers used for cracking Coula edulis nuts by wild chimpanzees in the Taï National Park, Côte d'Ivoire, taking into account the availability of potential tools at the site and time at which each tool selection episode occurred. The researchers found that wild chimpanzees select the optimal tool for the task at hand by considering several variables and conditions at once, including the weight, the material and the hardness of the hammer, the location of the anvil and whether they needed to transport it over a distance...Read more at: /phys.org
