Plesiadapiforms are attributed to which order?

Plesiadapiforms are classified within the order known as Proprimates. This group is considered to be an early branch of primate evolution, often representing some of the most primitive characteristics that predate the more modern primate lineages.

Plesiadapiforms share several traits that are distinct from those of Euprimates, which are the more derived forms of primates that include modern lemurs, monkeys, and apes. While both groups are part of the broader primate category, Plesiadapiforms are specifically categorized under Proprimates, emphasizing their transitional status in primate evolution.

The term Prosimian generally refers to a subset of more modern primates, particularly the lemurs and lorises, rather than Plesiadapiforms, placing that classification outside the correct association. Therefore, identifying Plesiadapiforms with Proprimates acknowledges their unique characteristics and position in the evolutionary lineage leading to true primates.
