Dr. Shapiro came to this conclusion in part because he found that it takes two copies of the mutant gene to reverse the feathers. Pigeons also played a pivotal part in both WWI and WWII, unerringly delivering vital messages that helped to save the lives of thousands of civilians and combatants alike.

Thomas Jefferson designed a grand dovecote for Monticello, complete with pillars. The discovery that birds evolved from small carnivorous dinosaurs of the Late Jurassic was made possible by recently discovered fossils from China, South America, and other countries, as well as by looking at old museum specimens from new perspectives and with new methods. Researchers have found that mutations in pigeon DNA can control a variety of traits, including the directions their feathers grow, like in this Jacobin pigeon. The scientists are following Darwin’s example by using the birds to find clues to the way evolution works in general. Kits (flocks) of the best racers can be valued at over $100 million, with champion individuals selling for up to $330,000. A few pigeon breeds have fuzzy legs—which hobbyists call "muffs"—rather than scaly ones. This chapter reviews recent experiments from my laboratory looking at how pigeons process hierarchically-arranged information presented at different spatial scales.” DNews is dedicated to satisfying your curiosity and to bringing you mind-bending … If you look at how they are related on a family tree, the evolution of feathers doesn't seem quite so impossible. Before long, Dr. Shapiro was following Darwin’s steps and raising pigeons of his own at the university, crossing the breeds to produce hybrids.

According to the article in Science, the large population size appears to have enabled passenger pigeons to adapt and evolve more quickly, and thus remove harmful mutations. They also displayed certain hallmarks of what’s called orthographic processing, which is the visual system that allows the brain to form, store, and recall words – one of several factors that humans use to read.

Graphic: How Tyrannosaurus rex evolved into modern bird . 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). Historically, however, Genghis Khan used the pigeon post to stay in contact with distant points of his empire, and even in ancient Greece, homing pigeons were used to announce major events, like the Olympics!
