Physiognomy personality. Physiognomy is also sometimes referred to as anthroposcopy, though the expression was more common in the 19th century when the word originated. Notions of the relationship between an individual's outward appearance and inner character are historically ancient, and occasionally appear in early Greek poetry. Siddhars from ancient India are also known to have defined "samudrika lakshanam" that identifies personal characteristics with body features. Chinese physiognomy or face reading ("mianxiang") reaches back at least to the Northern Song period. The first indications of a developed physiognomic theory appear in fifth century BC Athens, with the works of Zopyrus (who was
Brain-to-body mass ratio have spinal cords, or in some cases, central nervous systems. Recent research indicates that, in non-human primates, whole brain size is a better measure of cognitive abilities than brain-to-body mass ratio. The total weight of the species is greater than the predicted sample only if the frontal lobe is adjusted for spatial relation. The brain-to-body mass ratio was however found to be an excellent predictor of variation in problem solving abilities among carnivoran mammals. In humans, the brain to body weight ratio can vary greatly from person to person; it would be much higher in an underweight person than an
