All living tetrapods (four-limbed vertebrates) inherited the same basic forelimb structure from their shared ancestor—one long bone in the top, two long bones in the middle, and five digits. Variations in the shape, size, and number of bones have evolved in different groups. Explore the forelimb adaptations of chameleons, Bambiraptor and aye-ayes in the videos below.
