Human

Humans, scientifically known as Homo sapiens, are primates that belong to the biological family of great apes and are characterized by hairlessness, obligate bipedality, manual dexterity with opposable thumbs, precision grip, and high intelligence. Humans have large brains compared to body size, enabling more advanced cognitive skills that facilitate successful adaptation to varied environments, development of sophisticated tools, and formation of complex social structures and civilizations. Humans possess a disproportionately larger volume of both cerebral white matter and gray matter present in the prefrontal cortex (PFC) than any other primate species, which facilitated the expansion of higher-order executive functions.
