Summary
Highlights
From day one, a human raised by gorillas would transition from a soft diet to raw plants, bamboo shoots, and termites, causing an immediate shift in gut microbiome to process high fiber amounts.
By year three, walking upright would be replaced by knuckle walking to keep up with the troop, leading to thickened wrists, a strong core, and a permanently hunched spine. By year 10, constant climbing and swinging would result in incredible grip strength, making the individual an elite athlete compared to average humans.
By year 15, human language would be lost, replaced by vocal grunts, facial expressions, and chest beats for communication. Perception of the jungle would be heightened, allowing the individual to smell predators from miles away.
By year 20, biological changes would become permanent, with bones set and the brain rewired for the wild. Human society would then become an alien and unfamiliar world to the individual.
