Understanding Feather Development
A recent study from the University of Geneva reveals how the sonic hedgehog (Shh) pathway influences the evolution and diversity of feathers. Researchers found that inhibiting this pathway significantly disrupts feather development in chickens. Specifically, it restricts feather bud outgrowth, invagination, and branching, leading to impaired feather formation.
This groundbreaking research sheds light on the intricate mechanisms behind feather evolution. By understanding the role of the sonic hedgehog pathway, scientists can gain insights into the evolutionary emergence of various feather types.
