Conferencia: ‘Vida y muerte entre los primeros pobladores Neolíticos del Alto Pirineo: La cueva de Els Trocs’



El Instituto de Estudios Altoragoneses, desde su área de arqueología, desea dar a conocer importantes excavaciones que se están realizando en la provincia de Huesca. Así, el próximo día 29 de julio, a las 20:30 horas, en el Espacio Pirineos de Graus, se impartirá la conferencia: Vida y muerte entre los primeros pobladores Neolíticos del Alto Pirineo: La cueva de Els Trocs, a cargo de Manuel Rojo y José Ignacio Royo. Investigadores que dirigen desde el año 2010 un equipo multidisciplinar que excava en esta cueva, gracias a unas condiciones de conservación excepcionales que la han convertido en uno de los yacimientos fundamentales para entender el Neolítico en el Pirineo y en la Península Ibérica.

Miércoles 29 de julio. Espacio Pirineos. 20:30 horas.

La conferencia será presentada por la arqueóloga Julia Justes y está organizada por el Instituto de Estudios Altoaragoneses en colaboración con el centro Espacio Pirineos. espaciopirineos.com

El cambio climático llevó a la extinción de la megafauna


 
Un análisis que contempla variaciones climatológicas, periodos temporales y estudios genéticos de fósiles ha revelado que las oscilaciones térmicas llevaron a la extinción a grandes mamíferos

El Pleistoceno fue un periodo geológico que tuvo lugar entre hace más de dos millones y medio de años y unos 12.000 antes de nuestra era. El final de esta época, la última parte de la historia geológica de la Tierra, estuvo marcado por la última gran glaciación y por la extinción de la megafauna. Hasta ahora se pensaba que la desaparición de los grandes mamíferos venía motivada solo por la acción del hombre. Sin embargo, un estudio ha revelado que fueron grandes cambios climáticos en la última etapa de la edad de hielo los que favorecieron la adaptación de nuestros parientes lejanos y pusieron al borde de la extinción a la megafauna.

Archaeologists use new methods to explore move from hunting, gathering to farming

One of the enduring mysteries of the human experience is how and why humans moved from hunting and gathering to farming. 

Arizona State University. From their beginnings humans, like other mammals, depended on wild resources for sustenance. Then between 8,000 and 12,000 years ago, in a transitional event known as the Neolithic Revolution, they began to create and tend domestic ecosystems in various locations around the world, and agriculture was born.

Despite decades of research into this major human advancement, scientists still don't know what propelled it.

The recent work of a research team led by Arizona State University postdoc Isaac Ullah narrows the mystery by showing what variables might have affected the transition.

Ullah is an archaeologist in the School of Human Evolution and Social Change in the College of Liberal Arts and Sciences. Most of his research uses dynamical systems theory (DST) and centers on understanding the ways in which human societies changed with the advent of plant and animal domestication. [...] EurekAlert!

Tanzania to host scientific conference: Discovery of early man



TANZANIA (eTN) - International scientists and researchers of the origin of man are set to meet in Tanzania’s capital city of Dar es Salaam early August to discuss and review scientific findings of the history of the first human being.

Hosted by the East African Association for Paleoanthropology and Paleontology (EAAPP), the four-day scientific conference is expected to attract scientists and historians to sit together and review their work on the discovery of early man in East Africa.

Sources from EAAPP offices in Tanzania and Kenya said the researchers will hold their fifth biannual conference in Dar es Salaam from 3rd to 6th August.

EAAPP is currently commemorating the height of the 50th anniversary of the milestone discovery of the remains of early man on earth and which the specimens are preserved at the National Museum of Tanzania and the Olduvai Museum in Ngorongoro Conservation Area in northern Tanzania.

Named “Zinjanthropus” or Homo habilis (OH7), the discovery of this humanoid skull with huge teeth allowed scientists to date the beginnings of mankind between two and 3.5 million years ago, and to verify that human evolution began not in Asia, as previously thought, but in Africa.

Fort dig unearths 'evidence' Cardiff is 6,000 years old


  
The excavation of an Iron Age hillfort in Cardiff has revealed the "most compelling evidence yet" the city dates back 6,000 years, archaeologists said. 

A dig at Caerau Hillfort revealed a Neolithic causeway enclosure and one of the largest collections of pottery from the period ever discovered in Wales.

Animal bones, stone axes, flint tools and a Roman brooch were also found.

Cardiff University archaeologists said the finds "surpassed" expectations.[...] BBC News  /  Link 2
