Ontogeny of the anuran urostyle and the developmental context …
Fusion of caudal vertebrae has evolved multiple times independently: the pygostyle of birds, coccyx in apes and humans, ural plate of fish, and the urostyle of frogs. The anuran urostyle, however, is structurally and developmentally distinct because of …

2024年8月28日 · The anuran (frog and toad) urostyle, composed of a coccyx and a hypochord, is morphologically unique from the rest of the vertebrates because of the contribution of an ossifying hypochord, and is therefore considered a structural novelty [6 – 10].
The anuran (frog and toad) urostyle, composed of a coccyx and a hypo-chord, is morphologically unique from the rest of the vertebrates because of the contribution of an ossifying hypochord, and is therefore considered a structural novelty [6–10].

2024年8月28日 · Evolutionary novelties entail the origin of morphologies that enable new functions. These features can arise through changes to gene function and regulation. One key novelty is the fused rod at the end of the vertebral column in anurans, the urostyle. This feature is composed of a coccyx and a hypochord, both of which ossify during metamorphosis.

2020年2月11日 · It forms as the tail regresses during metamorphosis, when locomotion changes from an axial-driven mode in larvae to a limb-driven one in adult frogs. The urostyle comprises of a coccyx and a hypochord. The coccyx forms by fusion of caudal vertebrae and has evolved repeatedly across vertebrates.
Ontogeny of the Anuran Urostyle: The Developmental Context of ...
Frog metamorphosis, where tissue coordination is mediated by thyroid hormone (TH), involves dramatic changes in locomotion. During this period, a remarkable transition from swimming using fins/tails (in tadpoles) to jumping, walking, digging, climbing, and swimming using limbs (in adults) occurs (an axial-driven to a limb-driven transition).
