While webbed feet were evolving in ancestral ducks, with each generation: Most ducks had about the same amount of webbing on their feet as their parents. c)The branch leading to the Ocelot became reproductively isolatedfrom the branch leading to the Domestic Cat before the branch leading to the Domestic Cat became reproductively isolated from the branch leading to the Asian Leopard Cat. These mutations were beneficial to many semiaquatic animals because the increased surface area from the webbing allowed for more swimming propulsion and swimming efficiency, especially in surface swimmers. In order to achieve speeds higher than hull speed, some ducks, like eider ducks, use distinctive modes of locomotion that involve lifting the body out of the water. pp.19-end of chapter.

Aquatic control surfaces of non-piscine vertebrates may be paddles or hydrofoils. Imagine a population of mice living in a grey, rocky environment. Only the top statement is correct. to the fact of evolution. This is in contrast to a more hydrofoil-like flipper of many permanently aquatic animals.[7]. A bird may lift its foot away from its body on the forward stroke, actually giving itself a little extra lift and speed.

However, some waterfowl also utilize lift-based modes of propulsion, where their feet generate hydrodynamic lift due to the angle of attack of the foot and the relative water velocity.
