An important step in the evolution process is natural selection. Alfred Russel Wallace studied similarities and differences of plants and animals on the _ Archipelago and independently proposed a similar explanation of evolution as Darwin. A bird may lift its foot away from its body on the forward stroke, actually giving itself a little extra lift and speed. [6] Most waterfowl use a combination of these two modes of propulsion, where the first third of their foot stroke generates propulsive drag and the last two-thirds of the stroke generates propulsive lift.
