An international team of researchers analyzed ancient DNA from nearly 300 individuals from the Iberian Peninsula, spanning more than 12,000 years, in two studies published today in Current Biology and Science . The first study looked at collecting hunters and early farmers living in Iberia 13,000 and 6,000 years ago. The second looks at individuals in the region during all time periods over the past 8000 years. Together, the two reports greatly increase our knowledge of the history of the population of this unique region.
The Iberian Peninsula has long been considered a state of emergency in the history of the European population because of its unique climate and location on the westernmost edge of the continent. During the last Ice Age, Iberia remained relatively warm, allowing plants and animals ̵

Iberian hunter-gatherers show two ancient paleolithic lines
About the article in Current Biology of the Max Planck Institute of Science for Human History, researchers analyzed 11 harvester-hunters and Neolithic individuals from Iberia. The oldest newly discovered individuals are about 12,000 years old and have been recovered from Balma Gylanya in Spain.

Earlier evidence shows that, since the end of the last Ice Age, western and central Europe dominated hunter-gatherers with ancestors associated with an approximately 14,000-year-old person from Viliberona, Italy. It is believed that Italy was a potential refuge for people during the last Ice Age, such as Iberia. The genealogy associated with Villabruna has largely replaced its earlier ancestors in Western and Central Europe, linked to individuals from 19,000-15,000 years of age, associated with what is known as the Magdalen Cultural Complex. Interestingly, the findings of this study show that both genera were present in Iberian individuals dating back 19,000 years ago. "We can confirm the survival of an extra Paleolithic family that dates back to the late Ice Age of Iberia," said Wolfgang Haak of the Institute for the Study of Human History, Max Plank, senior author of the study. "This confirms the role of the Iberian peninsula as a refuge during the last ice peak, not only for flora and fauna, but also for the human population." Prehistoric hunter-gatherers.

"Iberian Gunmen a combination of two older types of genetic ancestors is one that dates back to the last ice age and was once increased in individuals attributed to Magdalen culture and another that occurs everywhere in Western and Central Europe and has replaced the Magdalen line during the early Holocene everywhere except the Iberian Peninsula, Vanessa Vialla-Muco of the Institute for Science for Human History explains Max Planck, the first author of the study.
Researchers hope that continuing efforts to decipher the genetic structure of groups of later hunter-gatherers in Europe will help an even better understanding of Europe's past and, in particular, the assimilation of a Neolithic way of life,
Ancient DNA from individuals spanning the last 8000 years helps to elucidate the history and prehistory of the Iberian peninsula
The paper published in Science is focus on small later periods of time and traces the history of Iberia population over the past 8000 years by analyzing ancient DNA from a huge number of individuals. The study, led by the Harvard Medical School and the Broad Institute, and including Haak and Wilabba-Muco, analyzed 271 ancient Iberians from Mesolithic, Neolithic, Copper Age, Bronze Age, Iron Age, and Historical Periods. The large number of people allowed the team to draw more detailed conclusions for each time period than was possible before.

Furthermore, the researchers looked at historical periods, including the times when Greek and later Roman settlements existed in Iberia. Researchers have found that at least during the Roman period the origin of the peninsula has been transformed from the gene pool of North Africa and the Eastern Mediterranean. They found that the Greek and Roman settlements were very multiethnic, with individuals from the Central and Eastern Mediterranean and North Africa, as well as from the locals, and that these interactions had a lasting demographic and cultural impact. "Beyond the specific ideas of Iberia, this study serves as a model for how a highly resonant ancient DNA transect can be used, which continues in historical periods to give a detailed description of the formation of today's populations," explains Haak, We hope that future use of such strategies will provide equally valuable insights into other regions of the world.
