Five fingers per hand tends to be the norm in the animal kingdom, but scientists have documented several cases in which organisms feature a sixth finger, an anatomical quirk known as an accessory digit. An extra digit among giant pandas, for example, improves their grip, while for moles and some extinct reptiles, the bonus extremity allows for more powerful digging through dirt and more efficient swimming. Aye-ayes feature a specialized middle finger, which they use to poke grubs out from trees. Image: David Haring/Duke Lemur Center New research published this week in the American Journal of Physical Anthropology describes a previously unknown sixth finger in aye-ayes, making it the first primate known to have an accessory digit. As in giant pandas, the aye-ayes extra digit compensates for an otherwise missing thumb, hence its designation as a pseudothumb. And because both aye-ayes and pandas use the pseudothumb to improve their grasping abilities, the feature is considered an example of convergent evolution, in which the same trait emerges spontaneously in unrelated species. The pseudothumb is also a striking example of contingent evolution, in which a species evolves an adaptive trait to compensate for a highly specialized pre-existing trait that, whi
