A scientist observes a prosimii in a natural habitat enclosure.

Definition

Noun 1. A taxonomic suborder of primates: In some biological classification systems, 'Prosimii' is the name for a suborder of primates that includes lemurs, lorises, bushbabies, and tarsiers. This grouping is based on shared primitive characteristics that distinguish them from the more advanced monkeys and apes (Anthropoidea). This classification is not universally used in modern taxonomy.

Examples of Usage

• Noun:
  • The traditional order Primates was divided into two suborders: Prosimii and Anthropoidea.
  • Fossil evidence helps scientists understand the evolution of the Prosimii.

Advanced Usage

• Taxonomic Context: The term 'Prosimii' is primarily used in discussions of biological systematics and primate evolution. It represents a paraphyletic grouping, meaning it includes some, but not all, descendants of a common ancestor. Many modern classifications now place tarsiers with monkeys and apes in the suborder Haplorhini, while lemurs and lorises are placed in Strepsirrhini.

Variants and Related Words

• Prosimian (noun): A member of the group Prosimii; a primate of this type.
  • Lemurs are nocturnal prosimians native to Madagascar.
• Anthropoidea (noun): The suborder of primates contrasting with Prosimii, containing monkeys, apes, and humans.

Synonyms

• Lower primates (informal/descriptive): A non-taxonomic term sometimes used to contrast with "higher primates" (monkeys and apes), referring to their more primitive anatomical features.
• Strepsirrhines (in modern taxonomy): This term is often used for the group containing lemurs and lorises, which were part of the traditional Prosimii.

Notes on Meaning

The meaning of 'Prosimii' is entirely dependent on the specific biological classification system being referenced. Its primary definition is taxonomic. It is not a word used in everyday language but is specific to zoology and anthropology.
