Variations in the<unk><unk>  of humans, known as human looks, are believed by anthropologists to be an important factor in the development of personality and social relations in particular<unk>  attractiveness. There is a relatively low sexual dimorphism between human males and females in comparison with other mammals. However humans are acutely sensitive to variations in<unk><unk> , some theorize for reasons of evolution. Some differences in human<unk>  are genetic, others are the result of age or disease, and many are the result of personal adornment.
Some people have traditionally linked some differences in personal<unk>  such as skeletal shape with race, such as prognathism or elongated stride (but this is a controversial and sensitive matter). Different cultures place different degrees of emphasis on<unk><unk>  and its importance to social status and other phenomena.
