Fred Hoyle is a distinguished astronomer, as you pointed out. When he speaks about biological phenomena, I would not say that he speaks ex cathedra. As a matter of fact, one of the statements that Fred Hoyle made with Chandra Wickramasinghe is that actually insects are smarter than we think they are, but they're just not letting us know. — Eugene Scott [In "Resolved: That evolutionists should acknowledge creation" Firing Line, 4 December 1997, p. 42.]
