Scientists recreate ancient proto-feathers in chicken embryos, revealing evolutionary resilience in feather development.

While a transient over-expression of the gene can permanently turn feet scales into feathers, it is much harder to disrupt ...

Scientists now believe that feathers didn’t just appear suddenly in birds. Instead, they evolved step by step from much ...

This interaction is vital for proper guidance of developing axons. During embryonic development, Shh acts as a guidance ...

By injecting a molecule that blocks the Shh signaling pathway on the 9th day of embryonic development -- just before feather buds appear on the wings -- the two researchers observed the formation ...
