Human physical appearance is the outward phenotype or look of human beings. Image of a European female (left) and an East Asian male (right) human body seen from front (upper) and back (lower). Adult human bodies photographed whose naturally-occurring pubic, body, facial, but not head hair have been deliberately removed to show anatomy.
The term visible difference is a more neutral, encompassing descriptor for any physical characteristic that sets an individual apart from what is generally considered the societal norm. [4] This could be due to congenital conditions, acquired conditions, diseases, or even personal choices like tattoos or piercings.
A person's physical characteristics can signal cues to fertility and health, [14] [15] [16] with statistical modeling studies showing that the facial shape variables that reflect aspects of physiological health, including body fat and blood pressure, also influence observers' perceptions of health. [17]
Eye color is an example of a (physical) phenotypic trait. A phenotypic trait, [1] [2] simply trait, or character state [3] [4] is a distinct variant of a phenotypic characteristic of an organism; it may be either inherited or determined environmentally, but typically occurs as a combination of the two. [5]
A proposed definition for both terms as the "physical totality of all traits of an organism or of one of its subsystems" was put forth by Mahner and Kary in 1997, who argue that although scientists tend to intuitively use these and related terms in a manner that does not impede research, the terms are not well defined and usage of the terms is ...
Examples of human phenotypic variability: people with different levels of skin colors, a normal distribution of IQ scores, the tallest recorded man in history - Robert Wadlow - with his father. Human variability, or human variation, is the range of possible values for any characteristic, physical or mental, of human beings.
In De humana physiognomia (1586), della Porta used woodcuts of animals to illustrate human characteristics. Both della Porta and Browne adhered to the 'doctrine of signatures'—that is, the belief that the physical structures of nature such as a plant's roots, stem, and flower, were indicative keys (or 'signatures') to their medicinal potentials.
