Finding more bird pictures in my archive, this is a Pouter Pigeon, the look and the shape of the bird has been created through selective breeding. “The diversity of the breeds is something astonishing,” wrote Charles Darwin in his book, #OntheOriginofSpecies a work greatly informed by his experiments with the birds.

Pigeon breeding, Darwin argued, was an analogy for what happened in the wild. Nature played the part of the fancier, selecting which individuals would be able to reproduce. Natural selection might work more slowly than human breeders, but it had far more time to produce the diversity of life around us.

By crossbreeding the many species of fancy #pigeon, he showed that contrary to the commonly-held belief that there were two different species which led to the diverse lot of the domestic pigeons, they all arose from just one wild species: the Rock Dove (Columba livia). Though he professed to never developing a true fondness for the creatures, his fascination with them and interest in their origins allowed him to show himself that the theories he was developing were, in fact, probable, and he was not mistaking coincidence for causation.

One hundred and seventy-five years ago, Charles Darwin set out with a survey voyage, aboard the HMS Beagle, in what would be a groundbreaking expedition for his own theories, and the way the world would come to see the origin of species. Intrigued by the vast differences in the closely-related mockingbirds and finches on the #Galapagos, Darwin brought this curiosity home to England, and found a way to test his thoughts on speciation, using an animal equally admired and despised: the pigeon. Specifically, “fancy pigeons,” the odd, often comical, sometimes scary-looking breeds of pigeon, whose popularity and availability was burgeoning just as #Darwin needed specimens.
