Physiological differences

Humans are distributed across the globe except for Antarctica and form a variable species. In adults, the average weight varies from around 40 kg (88 pounds) for the smallest and most lightly built tropical people to around 80 kg (176 pounds) for the heavier northern peoples. Size also varies between the sexes, with the sexual dimorphism in humans being more pronounced than that of
