Darwin´s pigeons and the evolution of columbiforms: recapitulation of ancient genes

Domestic pigeons were extremely important in shaping Darwin’s theory of evolution: pigeons featured prominently not only in his “Origin of Species”, but also in his treatise on “Variation under Domestication”, in his “Descent of Man” and finally in his “Expression of Emotions”. Darwin saw the process of domestication as solid evidence demonstrating the power of selection. He argued convincingly that all domestic pigeon breeds (some 150 in his day) descended from one ancestral species, the Rock Dove (Columba livia), and that from this single species, humans selected directionally for colors, sizes, shapes, peculiarities of bill shape and length, plumage characteristics and voice qualities. While these domestic races achieved remarkable morphological differentiation under selection in the course of human generations, extant genera of pigeons (Columbiformes) have attained similar traits during the course of natural selection in the wild. We present a comparison of such characters between modern domestic breeds of the Rock Dove, the original Darwin´s Pigeons plus new breeds, and wild pigeon species to encourage further studies on their evolution in the light of molecular techniques not available at Darwin´s time.

His Eminence’s essay had an explosive effect, in accordance to the author’s confessed wish “to awaken Catholics from their dogmatic slumber about positivism in general and evolutionism in particular” . If in the view of certain Catholics the Darwinist doctrine does not seem to contradict Christian faith, Schönborn proved that the situation is not that simple.
