Anuran jumping is an explosive movement that requires rapid, synchronous hindlimb extension; however, the ancestral tetrapod bauplan is designed around asynchronous locomotion (i.e., lateral undulation). This raises the question as to the origin of synchronous locomotor behavior. It has been hypothesized that synchronous movement progressively developed from the motor training of a riparian feeding behavior. Lunge feeding has been proposed as a possible precursor to jumping in anurans, since it too involves rapid, synchronous hindlimb extension and is the ancestral feeding condition for both frogs and salamanders. In order to elucidate the relationship between jumping and feeding, we used high-speed video to quantify kinematics during jumping and feeding behaviors in the Northern Leopard Frog, Lithobates pipiens.
