This week - feathers! Development, morphology, evolution. This will be fun, and you know you want to see peacock feathers under a microscope.

The feather is a complex ectodermal organ with hierarchical branching patterns. It provides functions in endothermy, communication, and flight. Studies of feather growth, cycling, and health are of fundamental importance to avian biology and poultry science. In addition, feathers are an excellent model for morphogenesis studies because of their accessibility, and their distinct patterns can be used to assay the roles of specific molecular pathways. - quote and image From Chen et al (2017)
