Science, 21 November 1980, pp. TABLE I [1], The stroke of the foot through the water also generates vortices that aid propulsion. Could individuals of a species look different today than individuals of the same species did many generations ago? They shared common traits d) The populations of ducks evolved webbed Samantha Fowler, Rebecca Roush, James Wise. Most of these have interdigital webbing, as opposed to the syndactyly found in birds. becoming more acidic. She returned every week for 12 weeks to measure survival of tagged lizards. System of equations that has no solution - Math Tutor The push as the birds paddle plus the lift as they pull their feet forward add up to a powerful and efficient means of locomotion, one that might also propel frogs and other animals with triangular feet. Reptiles have webbed-footed representatives that include freshwater turtles and geckos. Many generations later, almost all ducks had more webbing on their feet. Without a complete understanding of evolution, * The three main purposes Fully aquatic mammals and animals typically have flippers instead of webbed feet, which are a more heavily specialized and modified limb. Most ducks had less webbing on their feet than their parents. For example, the oxygen-carrying protein myoglobin evolves more quickly than the D1 protein of photosystem II.
