The Adapid Group was a family of extinct primitive primates that lived during the Eocene Epoch. The Adapid Group is often referred to by different names such as Adapidae or adapiforms. Adapidae is considered a taxonomic family, which includes a group of primate-like creatures that were first discovered in the early 1800s. These creatures are also known by the name adapiforms because they had unique characteristics that were adapted to their environment. Additionally, they have also been called Adapoidea, Adapisoricidae, and Lemuriformes. Although the exact classification of these creatures is debated, they played an important role in the evolution of primates.
