Classification

Aye-Aye skeleton

The aye-aye is sometimes classified as a member of Lemuriformes, but others treat Chiromyiformes as a separate infraorder, based on their very reduced dental formula. [1] Gunnell et al. (2018) reclassified the putative bat Propotto as a close relative of the aye-aye, as well as assigning the problematic strepsirrhine primate Plesiopithecus to Chiromyiformes. [2]

Evolution

The molecular clock puts the divergence of Chiromyiformes and Lemuriformes at 50-49 million years ago. [1] [3]
