What is the meaning of the term physiognomy?
The term physiognomy can also refer to the general appearance of a person, object or terrain, without reference to its implied characteristics, as in the physiognomy of a plant community. Credence of such study has varied from time to time.
How are communities named on the basis of physiognomy?
Component communities recognized on the basis of physiognomy are named after the dominant life forms as for example, forest, grass land, desert community, etc. Major communities are sometimes divided into smaller segments on the basis of habitat, mainly on the basis of water contents in the habitats.
Is there any evidence that physiognomy really works?
No clear evidence indicates physiognomy works—but the rise of artificial intelligence and machine learning for facial recognition has brought a revival of interest, and some studies that suggest that facial appearances do “contain a kernel of truth” about a person’s personality.
Which is the first systematic work in physiognomy?
The first systematic physiognomic treatise to survive to the present day is a slim volume, Physiognomonica (English: Physiognomonics ), ascribed to Aristotle (but probably of his “school” rather than created by the philosopher himself). The volume is divided into two parts, conjectured to have been originally two separate works.
