Some time ago, a jaw and an ancient human skull have been found in northern Laos, two archaeological pieces that have provided great information, which adds to the evidence previously found that the first humans were physically very modern.

The skull was found in 2009 in a cave that the locals call Tam Pa Ling, in the Annamite Mountains, now part of Laos. This finding was made public in the publication Proceedings in 2012 and it was said that it was the oldest modern human fossil that had been found in the area of ​​Southeast Asia after which the results of the studies reveal important data on human migration in the region, positioning humans 20,000 years earlier than originally believed.

The results of the investigations carried out in this field reveal that the first human beings who migrated to the islands and coasts of Southeast Asia, after having done so in Africa, they also traveled inland a long time earlier than was first thought, between 46,000 and 63,000 years. For its part, the mandible was found at the end of 2010 and is approximately the same age as the skull, although unlike it, features modern and archaic human features.

As stated Laura shackelford, director of the study and professor of Anthropology at the University of Illinois (United States), together with Fabrice Demeter, from the National Museum of Natural History in Paris: “In addition to being very small in overall size, this jaw has a mix of features that combine traditional modern human anatomy with a fairly protruding chin, features that are much more common in archaic ancestors such as Neanderthals, with a fairly thick bone with which the molars were held in place”.

Is combination of traits has made many experts take an interest in them and some researchers have used some of these characteristics as proof that modern humans migrated to new regions and on their way crossed with the different archaic populations that populated those regions, from which they could emerge a fruit like the person whose skull or jaw was found a short time later.

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.
