The Aye-aye (Daubentonia madagascariensis) is a primate native to Madagascar that combines rodent-like teeth with a long, thin middle finger to fill the ecological niche of a woodpecker. It taps on trees to find grubs, then gnaws holes in the wood and inserts its finger to pull the grubs out. The Aye-aye is the only extant species in the family Daubentoniidae and infraorder Chiromyiformes. A second species was exterminated over the last few centuries.

Thesis abstract (1339 words)
On the other hand the association, in a same cluster, of the Daubentoniidae and Tupaia is an important data, even though the place of the Tupaia was the subject of multiple controversies: for some authors this group is very detached of the Strepsirhini, to see even completely outside of the group of the Primates.
The use of the method of the ‘linearized trees’ permit, while considering that the separation between Lorisidae and Strepsirhini intervened 62 millions of years ago (that is to say long after that Madagascar separated of the African continent, there are about 150 millions years) the evaluation of the main dates of divergence.
So the oldest separation (neighbor of 60 millions of years) is found for the Daubentoniidae and Tupaia divergence, whereas most recent (neighbor of 11 millions of years) is the one implying the Megaladapis and the Lepilemuridae.
