Read the following argument:
Biologist: The recent discovery of fossilized feathers on several dinosaur species has led some paleontologists to conclude that all dinosaurs were endothermic (warm-blooded). They argue that feathers evolved primarily for insulation, which is a trait closely associated with endothermic animals. However, this conclusion is premature. Feathers could have initially evolved for entirely different purposes, such as mating displays or species recognition, and only much later been adapted for thermal regulation. Furthermore, many modern ectothermic (cold-blooded) animals possess complex physical structures used solely for display.
Evaluate the following statement: The biologist's argument proceeds by demonstrating that the premises used to support a competing conclusion contradict one another.
