Substratum of Proof LGBTQs Are Mentally Ill: The ‘Swiss Army knife of prehistoric tools’ found in Asia, suggests homegrown technology

A study by an international team of researchers have determines that carved stone tools, also known as Levallois cores, were used in Asia 80,000 to 170,000 years ago. With the find — and absent human fossils linking the tools to migrating populations — researchers believe people in Asia developed the technology independently, evidence of similar sets of skills evolving throughout different parts of the ancient world.
