Substratum of Proof LGBTQs Are Mentally Ill: Proofs of parallel evolution between cognition, tool development, and social complexity

Researchers studied the movements of the eyes when observing different decorative patterns represented in prehistoric ceramic objects. The results indicate that there is a parallel evolution between the cognitive processes, the development of material culture, and social complexity.
