Y el año que viene más

Clausura de la escuela taller Málaga Prehistórica en La Araña

El Taller de Empleo ha tenido como objetivos primordiales la cualificación profesional de los alumnos-trabajadores y la puesta en valor de las Cuevas de La Araña.

El alcalde de Málaga, Francisco de la Torre, ha asistido hoy a la clausura de la escuela taller Málaga Prehistórica en La Araña. El acto se ha celebrado en el nuevo equipamiento municipal donde se ubica la sede del Taller de Empleo en calle Escritor Aguirre García s/n, en la barriada de La Araña.

El Taller de Empleo “Málaga Prehistórica” promovido por el Instituto Municipal para la Formación y Empleo del Ayuntamiento de Málaga (IMFE), y aprobado por el Servicio Andaluz de Empleo de la Junta de Andalucía (SAE) con un presupuesto total de 517.225,85 euros ha contado con una subvención del S.A.E.-Fondo Social Europeo por importe de 479.759,28 euros siendo cofinanciado por el Ayuntamiento de Málaga en un importe de 37.466,57 euros...

Museo de la evolución humana: memoria del futuro

En el año 2011 abrió sus puertas el Museo de la Evolución de Burgos. Surge como una prolongación de la labor de excavación e investigación realizada por el Equipo de Investigación de los yacimientos de Atapuerca y en conjunción con el Centro Nacional de Investigación de la Evolución Humana.

Viewpoint: Has 'one species' idea been put to bed?

Here, Prof Clive Finlayson looks back at the year's developments in human evolution research and asks whether recent discoveries rule out a well known idea about our ancestors.

Hobbits on Flores, Denisovans in Siberia, Neanderthals across Eurasia and our very own ancestors.

Given this array of human diversity in the Late Pleistocene, we might well be forgiven for thinking that Ernst Mayr's contention that "in spite of much geographical variation, never more than one species of man existed on Earth at any one time" had finally been put to bed.

It now seems that a high degree of diversity was also present in the Middle Pleistocene, revealed in the latest analysis of human teeth from that period.

Mayr, one of the great evolutionary biologists of modern times, proposed his single species idea in a Cold Spring Harbor Symposium, published in 1950.

The idea of a single species of human has received a great deal of criticism since Mayr's day but it has also had its vociferous advocates.

So, can we really conclude that the concept was fundamentally flawed on the basis of all the new - fossil and genetic - evidence? That depends on how we understand and define species...

A new analysis of the rare mitochondrial DNA haplogroup C4c in Native American populations shows that it has a parallel genetic history with the X2a haplogroup thought by some to indicate a connection between early Paleoindians in eastern North America and the Upper Paleolithic Solutrean culture in France and Spain.

According to Baharak Hooshiar Kashani, of the Dipartimento di Genetica e Microbiologia at the Universita di Pavia in Italy, and his several co-authors, C4c has clear roots in Asia and is found in Great Lakes and Great Plains Native American populations. These are the same areas in which the X2a haplogroup has been identified suggesting that “these two lineages possibly arrived together from Beringia with the same Paleo-Indian group(s) that entered North America from Beringia through the ice-free corridor between the Laurentide and Cordilleran ice sheets” at around 18-15,000 years ago.

The researchers further conclude that this finding “definitively dismisses the controversial hypothesis of an Atlantic glacial entry route into North America.”

The paper was published in the latest volume of the American Journal of Physical Anthropology, Vol. 147, pages 35-39.
