How Did the Aye-Aye Evolve? Going deep into the evolutionary journey of this ancient primate, uncovers its story of survival and adaptation in the thick forest of Madagascar where it is found. Let’s go through memory lane to discover how it evolved.
Ancient Roots of An Aye-Aye
The Aye-Aye is a member of the lemur family. The lemur family includes a group of primates that are found on the island of Madagascar.
After Madagascar separated from the African continent, the lemurs of the early times found themselves on isolated island.
Adaptations for Survival
Over the years, the lemurs found in Madagascar developed several features that would help them survive on the island of Madagascar. But the Aye-Aye stood out as being different.

One of the visible features of the Aye-Aye is its long middle finger which it uses to tap on the bark of trees for insects hidden beneath the tree barks.
This type of foraging by the Aye-Aye makes it stand out among other lemurs.
Surviving in the Niche
The Aye-Aye with its special foraging habits is found in the dense forests of Madagascar.
This part of the forest is where the Aye-Aye can see trees to tap on their barks and extract insects hidden in the bark of this trees in which other lemurs couldn’t reach.
Evolutionary Pressures
The process of evolution of the Aye-Aye had its challenges. As there are changes in climate and the landscape of Madagascar over the years, the lemurs were faced with a lot of pressures which helped shape their evolution.
Some lemurs were able to adapt to a diurnal lifestyle while other lemurs had to become nocturnal to avoid being in competition for resources.
Because of the nocturnal habits of the Aye-Aye and its special foraging, it found delight in the shadows of the night.
