PLATYRRHINY Meaning and
Definition
-
Platyrrhiny is a term used in anthropology and zoology to describe a certain physical characteristic of primates. It refers to a specific facial trait exhibited by New World monkeys, commonly found in Central and South America. The word platyrrhiny is derived from the Greek words "platys" meaning "flat" and "rhin" meaning "nose."
This characteristic can be observed in the wide and flat shape of the nostrils of these particular primates. Unlike Old World monkeys and humans, which have narrow nasal passages, New World monkeys possess a broad nasal structure that sets them apart. The flattened nose with nostrils pointing sideways is a distinctive trait of platyrrhine primates.
The notion of platyrrhiny is often used in comparative anatomy studies and evolutionary discussions as a means to categorize primates into two major groups - the New World monkeys (platyrrhines) and the Old World monkeys (catarrhines), including humans. This specific nasal structure of platyrrhines is advantageous for their habitat, facilitating their adaptation to various environmental conditions, including forest canopies and arboreal lifestyles.
Understanding the concept of platyrrhiny is essential in both biological and anthropological research, as it aids in distinguishing and categorizing primate species, studying their anatomical adaptations, and observing evolutionary patterns. Additionally, it serves as a basis for further investigations into the diverse characteristics and distinctions found within the primate family.

Etymology of PLATYRRHINY
The word "platyrrhiny" is derived from the combination of two Greek words: "platys" meaning "flat" or "broad", and "rhinos" meaning "nose". In scientific terms, "platyrrhiny" refers to a specific type of nasal structure found in certain primates, particularly New World monkeys. These primates are characterized by their relatively broad, flat noses, which are thought to be an adaptation to their arboreal (tree-dwelling) habitat. The term "platyrrhiny" was coined in the 19th century by biologist Thomas Huxley, who classified primate species based on their physical characteristics.
