Is the Aye-Aye really a close relative of humans?

    All primates are closely related to humans, but the aye-aye does not appear to be any more closely related than are the great apes. However, the aye-aye has many distinguishing characteristics that separate it from other lemurs, most significantly an elongated middle finger that moves independently of the other digits. The aye-aye uses this to tap wood for insects, probing for and removing insects it finds, drinking water, and grooming. Additionally the aye-aye has different teeth, a third eyelid, nipples located near its groin, and continually growing incisors. The aye-aye does have unusually large hands and brain, and is also the largest noctural primate, which may make it appear to be more closely related to humans.

    Close, but not too close.  The Aye-Aye is a member of the primate Suborder Strepsirhini, while we are in the Suborder Haplorhini, along with monkeys, chimps, and gorillas.  So, while the Aye-Aye is a closer relative to us than, say, a cat, ultimately we have closer relatives.
