In one of the caves in Bulgaria, human remains were discovered. After identification, scientists learnt that they can be considered as the oldest human remains in Europe. Fragments of several bones and molars belonged to Homo Sapiens. Studying them, the researchers reached the conclusion that these are the remains of one of the first ancient people who migrated to Europe. Science has been trying for a long period of time to determine the exact period that would indicate when the first people appeared in Europe.
After discoveries made in Bulgaria, the secrets of Homo Sapiens were revealed. Due to discovery in the cave of Bacho Kiro - at the foot of the Balkan Mountains - researchers found out that the remains are about 45 thousand years old, which means the first settlement of an ancient person dates from the same period.
The cave has long been known to archaeologists for its features, it is called a rich deposit of paleontological fossils. And the excavations have been carried out there since the middle of the last century. In 2015, repeated excavations are carried out there, since scientists suggested the presence of a special layer of sediments into which older artifacts could “imprint”.
The assumption was confirmed: there is a layer and there are the remains of the first man who migrated to Europe were discovered in it. Researcher Frido Welker from the The Max Planck Institute for Evolutionary Anthropology in Germany believes that modern technology, in particular a mass spectrometry method called ZooMS, helped establish the features of the found remains.
With its help, the sequence of proteins of hundreds of unidentified fragments of bones and teeth was determined. As a result, five basic proteins that belong to the initial Upper Paleolithic were identified.
Combining technological methods for studying ancient remains, including radiocarbon dating and mitochondrial DNA sequencing, scientists have estimated the age of fossils, calculating that ancient people occupied the territory of the Bulgarian cave about 45-46 thousand years ago. And they turned out to be the very first Hominidae that science became aware of.
