Harvard Medical School, through its paleogenomicist Qiaomei Fu, has recently presented the results of a genetic study carried out on a jaw of a Homo sapiens about 40,000 years old that was found in the Romanian cave of Pestera du Oase.

The jaw was found next to the skeletal remains of a bear inside this cave, whose name in Romanian means "Cave with bones”. This cave was discovered by a group of cavers 13 years ago, where to access it you have to do it diving through an underground river, which makes its access more complex.

In this study, it is advanced that this individual had a Neanderthal relative in 4 or 6 previous generations, demonstrating crossbreeding between Homo sapiens and Neanderthals, as the genetic study of the Ust-Ishim Man had been presented in 2014.

The discovery was presented at the Genome Biology meeting in New York and where it has always been questioned from the beginning that both humans and Neanderthals only interbred in the Middle East more than 50,000 years ago.

Fu explained that they performed different DNA sequencing tasks of a 40,000-year-old male jaw, which represents some of the first modern human remains on a continental level and after its studies it has been estimated that between 5 and 11% of that genome belongs to Neanderthal.

After analyzing how the own length of the inherited DNA chain, in principle of a neanderthal, gets shorter with each new generation and put it as a work pattern, Fu and his team determined that their ancestors were Neanderthals in the previous 4 or 6 generations.

It is also confirmed by different DNA tests that the existing arguments that both the teeth and the jaw united They had a mixture of both human and Neanderthal features, are true.

They spoke about their wisdom teeth since they showed a size much larger than that of Homo sapiens. Erik Tririkaus, a paleontologist at the University of Washington, who also had the opportunity to analyze the jaw as well as study the results of both Fu and his team, noted that: “I think it is something very reassuring that on some level there is a certain correspondence between what anatomy is telling us and what the study of genes is revealing to us.”.

After studying History at the University and after many previous tests, Red Historia was born, a project that emerged as a means of dissemination where you can find the most important news of archeology, history and humanities, as well as articles of interest, curiosities and much more. In short, a meeting point for everyone where they can share information and continue learning.
