Some common human physical features include walking upright, larger brains and hair that covers the body. Humans are able to adopt a stance that lets them walk upright. This is an evolutionary adaptation that took place during millions of years.

Humans feature a thin covering of hair across their bodies. When it gets cold, or when something surprises them, this hair stands on end. Goose bumps become visible when this happens.

While there are many features that separate humans from other types of animals, there is a lot of diversity within the species . For example, skin color can vary according to where a person is from or how often they move around. There are areas of sub-Saharan Africa where very dark skin is common, and in contrast Aboriginals have a yellowing brown skin that arose from their nomadic nature.
