It is a type of numerical aberration, Q:n many ways, modern human lifestyles are at odds with our bipedal locomotion. The vortices from the two feet do not interfere with each other; therefore, each foot is generating forward propulsion independently. a transcription factor, motor protein The webbed foot is a specialized limb with interdigital membranes (webbings) that aids in aquatic locomotion, present in a variety of tetrapod vertebrates. A major difference among finch species is in their beaks: both size and shape vary greatly.
