WEBBED FEET. “The webbing between digits of a foot, as in waterfowl like the flightless cormorant, generally reflects the lack of such cell death and thus reveals the largely unaltered embryonic limb bud as a sort of simple ontogenetic artifact, yet one that is still obviously functional as a webbed foot and that bears too on the evolution of the taxon when viewed in comparison with related taxa (e.g., a duck’s foot vs. a chicken’s).”
