Skeletal plasticity in response to embryonic muscular activity underlies the development and evolution of the perching digit of birds
Most birds have an opposable digit 1 (hallux) allowing the foot to grasp, which evolved from the non-opposable hallux of early theropod dinosaurs. An important morphological difference with early theropods is the twisting of the long axis of its metatarsal. Here, we show how embryonic musculature an...
