Biologists believe that ducks evolved from land birds that did not have webbed feet. 1983), p. 134. genotype, phenotype Webbed feet evolve in ancestral ducks with each generation. [1], The stroke of the foot through the water also generates vortices that aid propulsion. (c) Because aging is a natural process for all species, explaining its evolution through natural selection is insufficient. c. According to this tree are humans more closely related to lizards or salamanders? Biologists believe that ducks evolved from land birds that did not have webbed feet.

Birds have a wide span of representatives with webbed feet, due to the diversity of waterfowl. The vortices from the two feet do not interfere with each other; therefore, each foot is generating forward propulsion independently.
