““Wallace would have none of it. In reviewing The Descent of Man he wrote, ‘Are we to believe that the actions of an ever varying fancy for a slight change of colour could produce and fix the definite colours and markings which actually characterise species?’ Furthermore, he said, it was unacceptable to suggest that birds had an aesthetic sense. That would be crediting a bird with a human characteristic for which there was no evidence. It would be anthropomorphism at its most unjustified.””
