Biologists believe that ducks evolved from land birds that did not have webbed feet. concern of the evolutionist. And many birds have mastered a stroke that any human swimmer might envy. Start your trial now! In fact, non-believers appeared In spite of all the forcefeeding of evolution, the Its clear that webbed feet have been a big evolutionary hit. [6] However, one of the most common is the delta () or triangular shape seen in most waterfowl and frogs. Solved > Ducks are aquatic birds.

In fact, they're such a nifty adaptation that they evolved, independently, in several bird groups. Waterbirds usually have webbed feet for foot-based propulsion. The roughly triangular design of webbed feet, with a broad distal end, is specialized to increase propulsive efficiency by affecting a larger mass of water over generating increased lift. they say a student cannot comprehend biology. The fish and the chick have the most similar DNA sequences. While webbed feet were evolving in ancestral ducks: (a) With each . Individuals of this species varied in the amount of webbing in their feet, with some individuals having more webbing and some having less. Their feet are webbed and this trait makes them fast swimmers. Birds that inherited the beneficial random mutations associated with the webbed feet trait had more chances to survive and reproduce, passing this trait to the next generations. The amount of webbing on a duck's feet is a heritable trait Q6.8. This interesting purpose for the study indicates the intense Most ducks had about the same amount of webbing on their feet as their parents. Surface swimmers are speed-limited due to increasing drag as they approach a physically-defined hull speed, which is determined by their body length. webbing on their feet than their parents. frustrating to evolutionists. Recent research surprises those who study coral reefs, especially those who assume that they grow slowly. they tend to choose the creation model. Four hundred different species of birds have webbed feet. freedom of choice between the evolution and creation model, For example, great-crested grebes use solely lift-based propulsion due to their lateral foot stroke and asymmetric, lobated toes.
