understanding of how this morphological change arose in species where webbed feet were selectively advantageous. [19][20][21], In many species, webbed feet likely evolved to aid in generation of propulsion during swimming. 41, p. 103. Assistant Producer: Mark Bramhill --------------------------------------------------------------------------------- The interdigital membrane increases the surface area, which increases the propulsive drag the animal can generate with each stroke of its foot. those who do not comprehend evolutionism, so they can set
