Western and Clark's grebes utilize their lobated feet to generate nearly 50% of the force required to allow them to walk on water in elaborate sexual displays; they are likely the largest animal to "walk" on water, and are an order of magnitude heavier than the well-known lizards that exhibit a similar behavior.

The amount of webbing on a duck's feet is a heritable trait. [13] This demonstrates that webbed feet arise from developmental changes, but do not necessarily correlate with a selective advantage functionally. Alfred Russel Wallace studied similarities and differences of plants and animals on the _ Archipelago and independently proposed a similar explanation of evolution as Darwin.
