A study led by researchers from North Carolina State University has found that aye-ayes, extremely rare lemurs known for their constantly growing incisors, large ears, and strange hands -- particularly for the slender, elongated middle fingers that they use for locating and spearing grubs inside trees, possess small "pseudothumbs" -- complete with their own fingerprints -- that may help them grip objects and branches as they move through trees. This is the first accessory digit ever found in a primate.
