Part of the genome recovered from 2 hunter-gatherer individuals from 7,000 years ago

Part of the genome recovered from 2 hunter-gatherer individuals from 7,000 years ago

Monday, July 2, 2012

A team of scientists, led by researcher Carles Lalueza-Fox from CSIC (Spanish National Research Council), has recovered - for the first time in history - part of the genome of two individuals living in the Mesolithic Period, 7000 years ago. Remains have been found at La Bra?a-Arintero site, located at Valdelugueros (Le?n), Spain. The study results, published in the Current Biology magazine, indicate that current Iberian populations don't come from these groups genetically.

The Mesolithic Period, framed between the Paleolithic and Neolithic Periods, is characterized by the advent of agriculture, coming from the Middle East. Therefore, the genome found is the oldest from Prehistory, and exceeds ?tzi, the Iceman, in 1700 years.

Researchers have also recovered the complete mitochondrial DNA of one of these individuals, through which they could determine that European populations from Mesolithic Period were very uniform genetically. Carles Lauleza-Fox, from the Institute of Evolutionary Biology (CSIC-UPF), states: "These hunters-gatherers shared nomadic habits and had a common origin. Despite their geographical distance, individuals from the regions corresponding to the current England, Germany, Lithuania, Poland, and Spain, shared the same mitochondrial lineage".

The DNA data, which represent the 1.34% and the 0.5% of both individuals total genome, show that they are not directly connected to current populations of the Iberian Peninsula. Iberians from the Mesolithic Period were closer to current populations of northern Europe, who could have assimilated part of the genetic legacy of these hunters-gatherers.

La Bra?a-Arintero site was discovered in 2006 by chance. Juan Manuel Vidal Encinas, archeologist from the Regional Government of Castilla y Le?n, who has also participated in the study, has excavated it at a later date. The cave, due to its location in a cold and mountainous area, is a suitable place for the good preservation of the DNA of these two individuals, found inside it.

The oldest remains from Prehistory

CSIC researcher emphasizes: "So far, we only had one genome of the European Prehistory, that of ?tzi [also known as the Iceman], from the Neolithic Period. His mummy, belonging to a man who lived 5300 years ago, was found in the Tyrolean Alps, on the border between Austria and Italy. La Bra?a-Arintero site offers a unique opportunity to obtain pre-Neolithic genomes".

According to Lalueza-Fox, this is only a first result since the intention of the team is to recover the complete DNA of these individuals, and to compare it with that of the modern humans. CSIC researcher discloses: "The arrival of the Neolithic Period brought about a replacement of populations, and could cause genetic changes in genes associated with new infectious diseases, and in metabolic genes linked to changes in diet. Therefore, all the information extracted from this genome will be absolutely important".

NEW YORK (AP) ? The nation's new poet laureate will be telling her own story, in prose.

Natasha Trethewey is working on a memoir, currently untitled, that has been acquired by Ecco. The publisher, an imprint of HarperCollins, announced Monday that the book is scheduled to come out in 2014.

The 46-year-old Trethewey is the daughter of a white father and black mother. The memoir will tell of her childhood in the American South in the 1970s and '80s.

Trethewey won the Pulitzer Prize in 2007 for her collection "Native Guard." This fall, she begins a one-year term as U.S. poet laureate.

The Numerous Features Of A Hand Held Console | phoenix-printink ...

The first gaming console to be designed was in 1985, this gaming system was in fact the nintendo. Following the creation, a gameboy was introduced on the market in 1989 this was the first ever portable console that a number of people still play on right now. Tetris actually handed out 150 million consoles across the world, this game still seems to be one of the most played games available.

Much more gaming units followed over the years which consisted of the game boy advance, game boy advance sp and also the nintendo DS this was introduced in 2004. It was an important increase in modern technology by nintendo because it included WiFi a microphone and in addition touch screen! The DS also has invert gaming this means all games from older Nintendo models can be played on the DS.

The most recent and up to date was the nintendo dsi, Japan had the opportunity of initially checking out the system while the rest of the world was still anticipating its launching in April 09.

You?ll be able to go on the internet to get hold of a number of games and install them to your console.

During February 2011, the nintendo 3DS was then unveiled after it was initially released in Japan generally known as the nintendo giant. In actual fact, this is actually the 3rd product of the Nintendo DSI, you could furthermore play your DSI video games on this completely new console so you have much more of an assortment of games to play in contrast to sticking to the recently released video games. This nintendo 3DS in fact enables you to play 3D games which is a substantial advancement with regards to the recent models.

There is a chance you already know that the sony manufacturers are up to date with the gaming systems which they develop. The brand new Sony PS Vita was released in February 2012, this gaming system took this market by surprise when it was released. It is actually probably the most technically enhanced gaming console ever designed and its specs are extraordinary. The Sony PS Vita packs a huge punch which includes a quad core ARM Cortex cpu which flatters the 5inch. In addition it has blue tooth technology, duel analogue sticks together with front and rear touch screens.

Even though the Sony PS Vita is amongst the most beneficial games consoles on the market at this time there are still brand new improvements being put into practice, one of them involves the making of a remote Sony system. Having the ability to play video games on the vita will be a truly memorable opportunity, once this is released people will go outrageous for this product for a variety of years.
