Human and ape hands
Human and ape hands. Historical artwork of the hand of a human (left) and a barbary ape (Macaca sylvanus, right). The skin has been removed to reveal the underlying muscles and tendons. The human hand has a thick muscle that lies over the tendon to the thumb. This allows the thumb to be opposable to the other fingers. In the ape hand, the tendon to the thumb follows a similar path to those leading to the fingers, meaning it can only be moved in the same way as those digits

EDITORS COMMENTS
This print from Science Photo Library showcases the intricate comparison between human and ape hands. The historical artwork beautifully illustrates the underlying muscles and tendons of both species, with the skin removed to reveal their fascinating anatomy. On the left side, we observe the hand of a human, distinguished by a thick muscle that overlays the tendon leading to the thumb. This unique feature allows humans to have opposable thumbs, enabling us to grasp objects with precision and dexterity. In contrast, on the right side of this thought-provoking image, we see the hand of a barbary ape (Macaca sylvanus). Here, it becomes apparent that its thumb's tendon follows a similar path as those leading to its fingers. Consequently, unlike humans who possess opposable thumbs for versatile movements, apes can only move their thumbs in conjunction with their other digits. The detailed sketch not only highlights anatomical differences but also sheds light on our shared evolutionary history. It serves as an invaluable tool for comparative anatomy studies and contributes to our understanding of primate evolution. This remarkable piece of art offers viewers an opportunity to delve into medical science and explore how biological structures have evolved over time. By dissecting these hands through illustration, Science Photo Library provides us with an enlightening glimpse into our own origins while fostering appreciation for nature's diverse adaptations.
