Dopo 400mila anni, ecco il vero volto dell'Uomo di Ceprano


1/9

Nuova ricostruzione dell'antichissimo cranio rinvenuto nel Lazio nel 1994. Lo studio effettuato da un team di paleontologi dell'Università di Roma La Sapienza guidati da Giorgio Manzi: "E' compatibile con l'Homo heidelbergensis, ultimo antenato comune di Nearderthal e Sapiens"

La verità sull'Uomo di Ceprano arriva da una sorta di Tac. E' stato grazie a una micro-tomografia computerizzata ad altissima risoluzione realizzata presso il Centro Internazionale di Fisica Teorica “Abdus Salam” di Trieste che i paleontologi guidati da Giorgio Manzi hanno potuto digitalizzare e riassemblare gli oltre 50 frammenti che compongono il cranio fossile più antico d'Italia, svelandone alcuni misteri. A cominciare proprio dalla datazione: 400mila anni fa. [...] Repubblica.it

El cráneo de Ceprano (Italia) es uno de los ejemplares fósiles más estudiados del Pleistoceno de Europa. No es por casualidad ni por un capricho de los científicos que se encargan de su investigación. La morfología de este cráneo, al que le falta la cara, es un verdadero “expediente X”. El cráneo es grande, aunque […]

Humanos modernos y neandertales se mestizaron en Asia Occidental

Nueva evidencia genómica confirma un antiguo entrecruzamiento entre humanos modernos y neandertales, y que Asia occidental es el lugar más probable donde sucedió.

Un nuevo estudio explora el legado de estas citas interespecies. Publicada en Genome Biology and Evolution, analiza el material genético de las personas que viven en la región hoy, identificando las secuencias de ADN heredadas de los neandertales.

"En lo que respecta a la historia humana, esta área fue el trampolín para el poblamiento de toda Eurasia", dice en un comunicado Omer Gokcumen, profesor asistente de ciencias biológicas en la Universidad de la Facultad de Artes y Ciencias de Buffalo. "Aquí es donde los humanos se asentaron por primera vez cuando salieron de África. Puede ser donde conocieron a los neandertales. Desde el punto de vista de la genética, es una región muy interesante". [...] europapress.es


How Neanderthals influenced human genetics at the crossroads of Asia and Europe - University at Buffalo
The region holds a unique position in the story of human evolution

BUFFALO, N.Y. — When the ancestors of modern humans migrated out of Africa, they passed through the Middle East and Turkey before heading deeper into Asia and Europe.

Here, at this important crossroads, it’s thought that they encountered and had sexual rendezvous with a different hominid species: the Neanderthals. Genomic evidence from past studies shows that this ancient interbreeding occurred, and scientists believe that Western Asia is the most likely spot where it happened.

Now, a new study is exploring the legacy of these interspecies trysts,...

Is this proof early man weaponised ivory from woolly mammoth tusks to kill....woolly mammoths?

Deadly paleolithic spears - pictured here and manufactured from the ivory from extinct beasts - show the lethal genius of ancient craftsmen up to 28,500 years ago.

11/10/17. These deadly spear tips were all found in inhospitable Arctic areas of Yakutia, two made by Stone Age man from the tusks of woolly mammoths, the other hewn from the horn of a long-gone hairy Siberian rhinoceros.

Of the three, special interest currently surrounds the front end of a lance or javelin dating back 10,000 to 12,000 years, says Dr Semyon Grigoryev, Director of the Lazarev Mammoth Museum at Northeastern Federal University.

This weapon was found in the tundra close to the Syalakh River 'inside the ribs' of 'adult mammoth bones', he revealed.

It was dug last year from 'a known permafrost layer, which suggests it originates from the Upper Paleolithic time period'.

In other words, the mammoth tusk spear appears to have been used in an ambush attack by ancient man on a woolly mammoth at the time the creatures were veering towards obliteration.

The beast probably lumbered on but eventually expired with the spear still piercing its rib cage to be found by modern-day tusk hunters. [...] siberiantimes.com

8,600-year-old bear statuette unearthed in Turkey’s Izmir

Turkish archeologists have discovered an approximately 8,600-year-old bear statuette during excavation works in the Yeşilova Mound, in Turkey's western province of Izmir.

The Head of the Excavation Committee, Zafer Derin, reported that more than 200 important findings that reflect life in the Neolithic period were obtained during the excavations in the Yeşilova Mound, one of the oldest settlements near Izmir.

The five-centimeter-high bear statuette, made from baked clay, was one of the most interesting findings, Derin said. He said he believed that the bear was used as a toy, and to attract children to the wildlife.

Another unique discovery found in the same excavation is a 5,000-year-old baby bottle that resembles a little sparrow.

"Maybe it was used to give water or milk to babies some 5,000 years ago," Derin said. "You know the famous saying mothers tell their children when they don't want to drink milk 'look the bird is coming'? Maybe it came out thousands of years ago" he added.

Another ancient finding was an 8,000-year-old little house sculpture, which gives crucial details about the architecture of the Neolithic period. Daily Sabah

El libro “Historias de Tesoros. Tesoros con Historia” desvela los misterios de emblemáticas piezas de la protohistoria peninsular


 
La obra descubre la compleja realidad que rodea a tesoros como el de Villena, Sagrajas, Bodonal, Valdeobispo, Berzocana, Carambolo, Aliseda, Arrabalde..., desde la doble perspectiva de las circunstancias de sus descubrimientos y sus contextos histórico-arqueológicos

El director del Servicio de Publicaciones, Alfonso Pinilla y el coordinador de la obra, Alonso Rodríguez Díaz han presentado el libro “Historia de Tesoros. Tesoros con Historia” en el Rectorado de Cáceres, junto a los editores Ignacio Pavón Soldevila y David Duque Espino.

La obra es el resultado de un encuentro, que bajo el mismo nombre, se celebró hace un año en el campus cacereño.  Consta de 11 capítulos que giran en torno a los tesoros emblemáticos de la pre y protohistoria peninsular, fruto de distintos trabajos de prestigiosos especialistas.  [...] Universidad de Extremadura / Link 2
