ARQUEOLOGÍA – Guiro de guión in the history of the first pobladores of the Caribbean

The mayor’s study of ancient human DNA in the United States offers a much-needed insight into the history of the original Caribbean islands, combined with decades of archaeological work.

Published in the journal ‘Nature’ a team of international investigators, led by David Reich, of the Faculty of Harvard Medicine, the genetic genetics of the great migratory olives in the Caribbean for the distinct groups, with miles of different years, revealing an archipelago published by very mobile people, with bedridden living quarters in different islands.

The Reich laboratory has also developed a new genetic engineering technique to estimate the population growth rate in the past, which shows that the number of people living in the Caribbean when the Europeans read it was much less important than previously thought. miles, to lie of the million or more informed by Cristóbal Colón and his successors.

For archaeologist William Keegan, who worked in the Caribbean for over 40 years, the ancient ADN offered a new powerful tool to help resolve debates over long data, confirm hypotheses and unravel the remaining mysteries.

It’s dramatically advancing our Caribbean Caribbean’s one-year vacation – Keegan Senator, curator of the Florida Natural History Museum and co-author of the studio -. The methods that David’s team developed help us to understand what we mean by which we can afford “.

Archaeologists have confiscated the remains of domestic animals (ceramics, pottery, rabbit remains and bones) to reconstruct the passage. Now, the technological advances in the study of the ancient DNA are becoming new light on the movement of animals and humans, especially in the Caribbean, where each can have a unique microcosm.

While the caloric value and humidity of the tropics can rapidly decompose organic matter, the human body contains a cauldron of genetic material: a small and unusually dense part of the skin that protects the internal fluid.

Utilizing this structure mainly, the investigators will extract and analyze the DNA of 174 people living in the Caribbean and Venezuela between 400 and 3,100 years old, combining data with 89 presumed individuals.

The team, which includes Caribbean academics, receives permission to carry out the genetic analysis of local governments and cultural institutions that act as leaders of human remains. The authors also involve representatives of the Caribbean indigenous communities in a discussion about their halls.

Genetic evidence provides new knowledge about the Caribbean population. The first inhabitants of the islands, a group of peasants, navigating to Cuba has 6,000 years, gradually expanding this to other islands during the Archaic Edda of the region.

There is no clear evidence of donation: although there are more strained relationships with Central Americans and South Americans than North Americans, their genetics do not coincide with any indigenous group in particular. Syndembargo, artifacts similar to those found in Belice and Cuba can suggest a Central American origin, according to Keegan.

Between 2,500 and 3,000 years ago, the farmers and farmers involved with the Arabs of the Northwest of the United States of America established a second Caribbean truck. Using the dedication of the river Orinoco of the Americas of the South as a whole, travel from the interior to the coast of Venezuela and advance north to the Caribbean Sea, establishing Puerto Rico and finally moving east. On the other hand, the commencement of the Edam de la Ceramica of the region, marked by the Agriculture and Production and Uso Generalizados de la Ceramica.

At the same time, all genetic traits of the people of the Archaic Edca were disappearing, with the exception of a community of resistance in the western part of Cuba that persisted in the European League. The mixed matrimonios between the two groups are few and far between, and only three individuals in the study will show mixed ascension.

Many Cuban, Dominican, and Puerto Rican news of the ceremonial descendants of the Edad de la Cerámica, as well as European and African immigrant immigrants. But the investigators will only observe a marginal evidence of the ascension of the Archaic Edda in modern individuals. “This is a great mystery – Resale Keegan–. For Cuba it is especially curious that we have no more archaic ascension”.

During the Ceramic Era, caribbean ceramics experimented with at least five market changes in the style lasting 2000 years. The red ornamental ceramics decorated with white painted stripes fit simple beige vases, while there are only a handful of small points and incisions or ten carcasses of sculpted animals that are likely to be double-edged.

Some archaeologists report these transitions as evidence of new migrations to the islands. However, the DNA has a different history, which suggests that all the styles were developed by descendants of people who traveled to the Caribbean 2,500-3,000 years ago, although it is possible that they were interacted with and were inspired by extras.

“It was a question that quizzes on hibernation would not have done if we had hitherto an expert in archeology in our team – recognizes the principal author Kendra Sirak, postdoctoral fellow in the Reich laboratory–. the style of ceramics. Hablamos de ‘vasijas contra personas’ y, hasta donde sabemos, son solo vasijas “.

In addition to the interconnection of the region, a study of chromosomes X masculinos described 19 pairs of “genetic primers” that live in different islands, individuals that share the same amount of DNA that the biological primates before they can be separated by generations.

Discover a high proportion of genetic primates in a sample of less than 100 men is another indicator that the tamana of the total population of the region is small, results Reich, professor of genetics and the Institute Blavatnik of HMS and professor of biology human at Harvard. “When there are so many models of modern individuals, it is not uncommon to find that there are older relatives”, dijo. “Here, there are parentheses for all parties”.

A technique developed by the co-author of the Harald Ringbauer studio, postdoctoral fellow and the Reich laboratory, uses segmented segments of DNA to estimate the past tense, a method that can also apply to future student studies.

Ringbauer’s technique shows that between 10,000 and 50,000 people live in two of the largest islands in the Caribbean, Spain and Puerto Rico, just in front of the European League. This is very much due to the dispensation of one million residents that Colón described, Keegan signaled.

More recently, the historian of the XVI Bartolomé of the Casas affirms that the region has hosted 3 million people before being killed by slavery and European forces. Well, this is also an exaggeration, the number of people who murmur as a result of the colonization followed by an atrocity, punctualizes Reich. “This is a systematic program of cultural drilling. It is clear that the number does not carry 1 million or millions of people, over tens of miles, does not mean that drilling is significant”, he explained.
