A study of ADN reveals the mystery of how human beings will travel to the paradise islands of the Caribbean

When Juan Avilés fue a la escuela en Puerto Rico, the professors teach that the original inhabitants of the island, los taínos, desaparecieron poco despué de que España la colonizara. The professors affirm that Violence, Injuries, and the Forced Workers of Antiquity, destroying its culture and its idiom, and that the colonizers repoblaron la isla con enslavos, between the Central American, South American and African indigenous peoples.

No obstacle, in case, Avilés escuchó otra historia. Su abuela le decía que eran descendants of antepasados ​​taínos and that some of the phrases that are used also prove to be the idiom taino.

“But, I know, I have to leave the school in the second grade, if only in principle not trusted in it”, Comment Avilés, that now is medical in Goldsboro, Carolina del Norte.

Avilés, who studied genetics at the faculty of postgraduate, has started using this study area for help the caribbean connect with its genealogical history, and the recent in-camp investigation has led it to reconsider that su abuela tenía algo de razon.

For example, a study published on Wednesday in the magazine Earth, demonstrate that, in promedio, Alrededor del 14 por ciento de la ascendences la los inhabitant de Puerto Rico se. Off Cuba, is approximately the four per cent, while in the Dominican Republic there is well over six per cent.

These results, and other similar bases and DNA samples found in ancient Caribbean skeletons, is offering a more detailed panorama of the region. For example, we must show that Caribbean islands are popular in two separate leads and the human population of the islands was also reduced to what was created. Prohibition of sanctions, the inhabitants of the islands before the colonial contact not extinguished completely; Millions of people who live today are inherited from their DNA, along with rasters of their traditions and idioms.

Antes de llegada de los genetics studios de Caribe, los archaeologists proporionionar la Mayoría de las pistas acer de los origins de los pobladores de la region. Al parecer, the first human habitation of the Caribbean vivieron mainly as collectors-collectors, fishing in the islands and fishing in the lake, as long as there are small gardens.

The archaeologists have discovered some interiors of their ancient people. In the principles of the decade of 2000, logarithmic geneticists extract some DNA screens preserved in their houses. The significant advances of the last few years have made it possible to extract genomes enteros of ancient skeletons.

“We do not have any complete genomes until two months ago 200 in the news ”, signaled María Nieves-Colón, a genetics anthropologist at the University of Minnesota who has not participated in the new study.

The most ancient coniferous genes of the Caribbean have been known to vinculan with the primary populations which is centered in Central and South America.

“By supuesto, there is a population of indigenous natives, but there is a deep line very characteristic ”, assured David Reich, author of study and genetics at the Faculty of Medicine at Harvard University.

However, it is not clear from what specific location of the continent is being embedded in canoes that are indigenous indigenous peoples to visit the Caribbean islands.

“I do not believe that we are as close as we think to a response”, dijo Nieves-Colón, author of another genetic study on a large scale in July.

Part of the problem is that scientists aún has not found any DNA in the Caribbean that is more than 3000 years old. “There are many things that we can do because we do not have the ancient DNA”, says Nieves-Colón.

Agree with the archaeological records, have one 2500 years hubo a drastic cambio in the cultural life of the Caribbean. The people to start living in great awnings, where we cultivate mainly things like the corn and camote. Its ceramics are more sophisticated and elaborate. For archaeologists, the cambio marks the end of what is known as the Archaic Era and the beginning of a Ceramic Edad.

Nieves-Colón and other investigators have discovered that the DNA of the Caribbean islands also changed at the same time. The skeletons of the Edam de la Ceramica are now part of a new genetics company. So ADN the relationship with pequeñas tribus that included in the live news in Colombia in Venezuela.

It is possible that the migrants from the Caribbean coast of South America will be released idioms that all were said when Colón llegó 2000 years later. We do not know much about these languages, although some phrases and logos sobrevivir. For example, the palabra huracán came from hurakán, the word that designs to dios de las tormentas.

These phrases have a surprising appearance with the families of a lingua franca of South America called arahuacas lenguas. The DNA of the Caribbean Edam ceramics appears more like the arabic vivacious inhabitants.

In the Register of the Ceremony of the Ceramics, it is difficult to find people with much archaic ascension. To sobervivorize in some places, like the west of Cuba, you have to disappear a few years ago. The people with the ancestors of the Edad de la Cerámica llegaron a dominar el Caribe, casi sin ningún mestizaje entre los dos grupos.

For example, in the transcendence of the Edam de la Cerámica, each sails are sails new and surprising ceramic ceramics. Investigators have been suing for a long time as these cams reflect the plight of new groups of people in the islands. Sondeverbod, the ADN antiguo does not respond to this idea. It has a genetic continuity and traverses its drastic cultural changes. On the other hand, the same group of people in the Caribbean passed on a series of great social changes that archaeologists have not explained.

Reich and his geneticist colleagues also discovered lazos familiares que abarcaban todo el Caribe durante la Edad de la Cerámica. Descubrieron ten pairs of persons in different islands that share IDN segmented segments, signal of eran brackets quite strong. In one case, we will find the first long distance from the Bahamas and Puerto Rico, separated by more than 1300 kilometers.

This is a contradiction in terms of archeology’s influential theories.

“The original idea was that people would live in a house, establish a colony in another, and simply lay down all the rooms with the city of Provence,” he said. William Keegan, archaeologist of the Museum of Natural History of Florida and collaborator of the new investigation, “pero Genetic evidence suggests that these lesions develop during a long period”.

In other words, to be formed by aisled communities, The Caribbean is a well-traveled long distance ridge that people regularly catch in Canada. “Water is like a car”, says Nieves-Colón.

The genetic variations also allow the Reich and its colleagues calculate the prevalence of caribbean society preview contact with europe. El hermano de Cristóbal Colón, Bartolomé, sent maps to Spain mentioning a number of millions. The ADN suggests that there is a exaggeration: the genetic variations implied that the total population is reduced to tens of miles.

The colonization produces a great impact in the caribbean world and enormous change in his genetic profile, pero aun así la población de la Edad de la Cerámica se las arregló para transmit its gene to future generations. Now, with a population of one 44 million people, is probably que el Caribe contenga más ADN taíno que en 1491.

“We now have evidence to demonstrate that only our extinctions, only ours and others exist,” concluded Avilés.
