Variation in the physical appearance of humans is believed by anthropologists to be an important factor in the development of personality and social relations in particular physical 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 physical appearance for reasons of evolution.

Some people have traditionally linked some differences in personal appearance such as skeletal shape with race, such as prognathism or elongated stride (but this is a controversial and sensitive matter).

Some differences in human appearance are genetic, others are the result of age or disease, and many are the result of personal adornment.

A dandy is a man who devotes particular attention to his physical appearance. This is comparable to the metrosexual in modern times.

Physiological differences in human physical appearance from individual to individual

• Height, weight, skin color, sexual organs, moles, hair color and type, body shape, somatotype (ectomorph, mesomorph, endomorph), body deformations, mutilations and other imperfections such as amputations, scars, and wounds. Genital modification and mutilation is particularly common in some cultures.

Long-term physiological changes in an individual

• Aging

Short-term physiological changes in an individual

• Blushing, crying, fainting, sexual arousal, reddening of the skin due to increased blood flow due to exertion. Sweating, Shivering, skin colour changes due to sunshine

Clothing and personal effects
