Alfred Russel Wallace studied similarities and differences of plants and animals on the _ Archipelago and independently proposed a similar explanation of evolution as Darwin. Birds that inherited the beneficial random mutations associated with the webbed feet trait had more chances to survive and reproduce, passing this trait to the next generations. scientific evolutionary mechanisms. conceptions. as a suggested mechanism for evolution. The amount of webbing on a duck's feet is a heritable trait. The roughly triangular design of webbed feet, with a broad distal end, is specialized to increase propulsive efficiency by affecting a larger mass of water over generating increased lift. Fill in the bubble map by describing four industrial processes that make use of [28] In extreme cases, this type of behavior is used for sexual selection. After many years the aquatic food sources were more plentiful and after many generations, almost all ducks had more webbing on their feet. As part of answer, provide an example.
