Mitochondrial DNA Reveals the Origins of Chickens and their Incredible Popularity around the World

On the occasion of heading Thanksgiving Day, most of the American families put turkey, which a native bird to North America that was first tamed on table by the Mayans. But a small snatch of people around the world choose something else to serve, i.e. chicken the most often. Though, the chickens have an incredible popularity in the United States with Americans consuming nearly to 100 lbs. each person a year, what is the origin of chickens and how they are imported to the New World are quite dubious.

The chickens we are eating today seem to have all subsided from the red Jungle Fowl, the four existing bird species from genus Gallus in order of gallinaceous birds, which found in Sri Lanka, India and Southeast Asia. An era before the arrival of fasts, a budget DNA analysis traced the origins of chickens using their linguistics, history, archaeology, physical or morphology appearance.

But an article published in the scientific journal PLoS One (Public Library of Science) in 2012 by Alice Storey, an Australian anthropologist with her fellow workers used mitochondrial DNA to fathom out what the origin chickens belong to is and they brought all around the world.

the PLoS study mentioned in the article that, “Perhaps the most striking result reported is the evidence that the haplogroup E chickens were taken in opposite directions out of Asia, and their histories and dispersal pathways finally converged in the Americas after A.D. 1500.”
