How did running machines like the horse evolve from creatures that couldn't move on their own?
Official website: https://to.pbs.org/4sODQmc #novapbs
Run. Leap. Swim. Pounce. Slither. Fly. Life moves in countless ways—but it wasn’t always this way. When animals first emerged, they clung to the seafloor, until a single twitch sparked a revolution. From the first muscle to the first heartbeat, from lobe fins that pushed life onto land to legs built for speed, movement reshaped the planet. Follow the horse—perhaps the ultimate icon of power and endurance—as its limbs evolved into precision tools for running, and see how humans harnessed that power to amplify their own. This is the untold story of how life learned to move.
