Therefore Wheeler said that humans, who should have body hair based on predictions of body volume alone for savanna mammals, evolved no body hair after evolving bipedalism, which he said reduced the amount of body area exposed to the sun by 40%, reducing the solar warming effect on the human body.

The study uses a Bayesian hierarchical model to estimate the trends in mean height from 1985 to 2019. 1,344 academics having collated the results of 2,181 studies covering 65 million people. [219] Their findings are based on selected material rather than all available.

The height, weight, and head circumference of a child can be compared to the expected parameters of children of the same age and sex to determine whether the child is growing appropriately. Growth charts can also be used to predict the expected adult height and weight of a child because, in general, children maintain a fairly constant growth curve.
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. [2] Size also varies between the sexes, with the sexual dimorphism in humans being more pronounced than that of chimpanzees , but less than the dimorphism found ...
