Quite often we see images of human evolution, from ape to our current form of human self. We don’t often however look at illustrations of animal evolution. Which in the chicken's case, we would call Ovolution.
This concept of chicken ovolution was first predicted by Nostradamus in 1556, it was forgotten through medieval times but was remembered again by Benjamin Franklin in 1784. The phrase Ovolution was coined that night by Benjamin, as he mentioned it to his friend, who snickered at the idea. By morning both had forgotten about the concept.
Einstein explored the theory of ovolution in depth, and managed to make a sketch of it on a piece of paper.
Finally the important theory of Ovolution drawings are available to the general public, printed on this shirt.
