Behavioral evidence for the evolution of walking and bounding before terrestriality in sarcopterygian fishes

Tetrapods evolved from sarcopterygian fishes in the Devonian and were the first vertebrates to colonize land. The locomotor component of this transition can be divided into four major events: terrestriality, the origins of digited limbs, solid substrate-based locomotion, and alternating gaits that u...
