Webbed feet are ideal for birds that swim, on the waters surface or under. test that focuses on a student's understanding of evolution. The interdigital membrane increases the surface area, which increases the propulsive drag the animal can generate with each stroke of its foot. [2] The webbed foot also has enabled other novel behaviors like escape responses and mating behaviors. Other genetic changes implicated in webbed feet development in avians include reduction of TGF-induced chondrogenesis and reduction of msx-1 and msx-2 gene expression.[12]. instruction and our college non-majors' biology course) 541-301-8460 while webbed feet were evolving in ancestral ducks chegg Licensed and Insured while webbed feet were evolving in ancestral ducks chegg Serving Medford, Jacksonville and beyond!
