Human physical appearance

There are functionally infinite variations in human phenotypes, though society reduces the variability to distinct categories.

Some people have linked some differences with ethnicity, such as skeletal shape, prognathism or elongated stride.

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.

[3] The colouration of skin, hair and eyes also varies considerably, with darker pigmentation dominating in tropical climates and lighter in polar regions.
