WebThe fin-to-limb transition is characterized by the loss of fin rays (dermal skeletal rods that support the fin web) and the evolutionary origin of digits (1–3).Traditionally, efforts to explain how limbs evolved from fins have focused on transformation and novelty in the … Proceedings of the National Academy of Sciences of the United States of ... WebAug 4, 2024 · The overall structure of the grasping mechanism adopts the Fin Ray effect. The structure of the Fin Ray is a V-shaped frame with two bones on the sides and several ribs connected in between. For the VSG, the frame is designed as compliant, and the four ribs that support the frame have convertible angles, to realize discrete stiffness adjustment.
