A wise man Arriving in Southeast Asia 86,000 years ago, a human jaw bone fragment was found inside a cave in Laos.
The discovery comes from the cave Tam Pa Ling, or Cave of the Monkeys, is located on a mountain in northern Laos about 3,840 feet (1,170 meters) above sea level. Fragments of human bones Previously discovered in the cave 70,000 years old, they are some of the earliest evidence of human presence in this part of the world. The discovery prompted archaeologists to dig deeper.
The team did just that, finding two new bones, they reported in a study published Tuesday (June 13) in the journal. Natural communication. The bones – fragments of the front of a skull and a jawbone – may have been washed into Tam Pa Ling Cave during a monsoon. Although the bones were broken and incomplete, the researchers were able to compare their dimensions and shape to other bones from early humans, and found that they matched very closely. A wise man than other primitive men, such as standing manNeanderthals or Denisovans.
The researchers used luminescence dating of nearby sediments and uranium-series dating of mammal teeth from the same layers to develop an age range for the human remains. Luminescence dating is a technique that measures the last exposure of crystalline materials, such as stones, to sunlight or heat, while U-series dating is a radiometric technique that, like carbon-14 dating, measures the decay of uranium over time. Thorium, Radium and Lead. The skull is 73,000 years old, and the jawbone is 86,000 years old.

This early date is a significant discovery, especially since researchers have long debated the timing A wise man’Visit to Asia.
„No anthropological research has been done in Laos since World War II,” said the study’s lead author. Cloth Demeter, paleoanthropologist at the University of Copenhagen, told Live Science in an email. Debates about the human migration of Southeast Asia have for decades attempted to understand how and when humans crossed the straits and seas and eventually ended up in Australia. Tam Pà Ling is therefore „an important place to ask some of these questions about migration, because Southeast Asia really sits at the crossroads of East Asia and SE Asia/Australia.”

The genetic and stone tool evidence accumulated to date strongly supports a single, rapid dispersal A wise man From Africa Sometime 60,000 years agoStudies such as these produce evidence of earlier migrations, many of which may have been dead ends.
Michael BC RiveraA biological anthropologist at the University of Hong Kong, who was not involved in the study, told LiveScience in an email, „Perhaps this was a group that dispersed throughout Southeast Asia and died out before contributing genes to the present-day human genome. I find it interesting to include the narratives of these 'failed’ populations so that only the 'successful’ ones 'made it’.” We haven’t seen it.”
No stone tools or other traces of these people’s lifestyles have been found at Tam Pà Ling. But archaeologists working in prehistoric Asia have long suspected that ancient humans were capable of crossing seas to reach islands and populate remote parts of the world before 65,000 years ago, Rivera pointed out.
” said H. Wisely „The arrival of 60,000 years ago to this area is not new, but it is good to have further confirmation in our efforts to fill in the gaps in the archaeological record,” Rivera said.
