Archaeologists unearth earliest complete human figurine in Cyprus

Archaeologists unearth earliest complete human figurine in Cyprus | Aux origines | Scoop.it

EXCAVATIONS at Ayia Varvara-Asprokremnos have uncovered the earliest complete human figurine currently known on Cyprus, the Antiquities Department said yesterday.

The age of the statue could range from 10,500 to 11,000 years old based on the fact it was discovered at a site that has been radio-carbon dated to between 8800-8600 BC.

The period marks the beginning of the Neolithic period in Cyprus at a time when the transition from hunting to farming economies was beginning throughout the Middle East.

Imhotep The African: Architect of the Cosmos

Imhotep The African: Architect of the Cosmos | Aux origines | Scoop.it

A few kilometers outside the modern city of Cairo, on a large, flat elevation at the edge of the Sahara overlooking the Nile, is the world’s very first architectural complex. Nearly 5,000 years old, the centerpiece of this mind-boggling complex is a huge stepped pyramid surrounded by strange temple-like structures, the lot contained inside a giant perimeter wall whose length is more than 1,500 meters.

Neolithic agriculture on the European western frontier: the boom and bust of early farming in Ireland

Neolithic agriculture on the European western frontier: the boom and bust of early farming in Ireland | Aux origines | Scoop.it

A multi-disciplinary study assessing the evidence for agriculture in Neolithic Ireland is presented, examining the timing, extent and nature of settlement and farming. Bayesian analyses of palaeoenvironmental and archaeological 14C data have allowed us to re-examine evidential strands within a strong chronological framework. While the nature and timing of the very beginning of the Neolithic in Ireland is still debated, our results – based on new Bayesian chronologies of plant macro-remains – are consistent with a rapid and abrupt transition to agriculture from c. 3750 cal BC, though there are hints of earlier Neolithic presence at a number of sites.

Habitable conditions on Earth will be possible for at least another 1.75 billion years - according to astrobiologists at the University of East Anglia. A true-color NASA satellite mosaic of Earth [Credit: NASA] Findings published today in the journal Astrobiology reveal the habitable lifetime of planet Earth - based on our distance from the sun and temperatures at which it is possible for the planet to have liquid water.

Une collision, de la glace et hop de la vie

Des chercheurs anglais viennent de publier un papier où ils expliquent comment le cosmos peut se transformer en une fabrique d'acides aminés, les éléments indispensables à l'apparition de la vie telle que nous la connaissons sur terre. Pour obtenir cette soupe magique, ce n'est finalement pas si compliqué. Il faut une bonne collision, de la glace et un peu de chance. Avec ce cocktail, la réaction au début de la vie peut se faire un peu partout... dans l'espace. Le procédé présenté par les anglais demande quelques molécules de base et engendre des éléments plus complexes comme les acides aminés. Ce principe alliant météorites et glace permettrait d'expliquer pourquoi la vie est apparue de façon aussi rapide sur terre. Au final, il n'a fallu que quelques centaines de millions d'années pour provoquer le déclenchement de la vie sur terre. Certainement juste après une période d'intenses chutes de comètes et de météorites. La terre n'est pas l'unique endroit où le procédé peut fonctionner. Par exemple, la lune de Jupiter, Europe, présente des quantités importantes de glace. Cette lune, en recevant des impacts réguliers de météorites est une bonne candidate pour devenir une usine à acides aminés.

Neanderthal diet more varied than previously thought

Neanderthal diet more varied than previously thought | Aux origines | Scoop.it

Why did anatomically modern humans replace Neanderthals in Europe around 40,000 years ago? One hypothesis suggests that Neandertals were rigid in their dietary choice, targeting large herbivorous mammals, such as horse, bison and mammoths, while modern humans also exploited a wider diversity of dietary resources, including fish. This dietary flexibility of modern humans would have been a big advantage when competing with Neanderthals...
