In fact the whale flipper, bat wing and human hand all have 5 fingers, the ancestral tetrapod condition. The process continued over time, and a very derived form of hyperphalangy, with six or more phalanges per digit, evolved convergently in rorqual whales and oceanic dolphins, and was likely associated with another wave of signaling within the interdigital tissues. The flippers of penguins became thicker, denser and smaller while being modified for hydrodynamic properties. The bones in the wing of a bat are similar to the bones in the flipper of a whale. You Swimming performance in sea lions is modulated by changes in the duration and intensity of movements without changing their sequence. Some flippers are very efficient hydrofoils, analogous to wings (airfoils), used to propel and maneuver through the water with great speed and maneuverability (see Foil). Between the fingers and the ulna and radius are the wrist bones. Who doesn't love being #1? Be the first to answer! This “tubercle effect” provides the whale with more lift, allowing it to tilt its flippers at a high angle without stalling.

The presence of interdigital webbing within the fossils of semi-aquatic Eocene cetaceans was probably the result of BMP antagonists counteracting interdigital apoptosis during embryonic limb development. Whales have flippers, instead of hands, so they don't have individual digits like humans do. 0. [7] Distinct substitutions in common genes created various aquatic adaptations, most of which constitute parallel evolution because the substitutions in question are not unique to those animals. Whale fossils have been found that have a pelvis (hipbone) and what appears to be a femur (the thighbone in humans) despite the fact This problem is pointed out by At high angles these bumps also reduce drag —an important benefit for the humpback’s long flippers, each being about one third of the whale’s body length.
