According to the text, what were the possible functions of feathers in early feathered theropods before the evolution of powered flight?

  • A: Primarily for powered flight.
  • B: Insulation, camouflage, and courtship display.
  • C: Water repellency and communication signals.
  • D: Aid in gliding and hunting.

Explanation

The text explicitly states: 'Among the possible functions of these early feathers were insulation, camouflage, and courtship display.' It also clarifies that feathers evolved 'long before powered flight,' which rules out options related to flight as a primary early function.
