alexandr402 [8]

<u>Answer:</u>

Recent evidence suggest that feathers evolved from scales and suggest that 'feathers and pycnofibers' could be homologous.

  • Scales and Feathers consist of 'two distinct form of keratin' so it was thought that 'each type was exclusive skin structure' but recent study suggests that they are developmental expressions of same skin structures.
