] As a result of this study, I must conclude that cooked
] flavor is a result more of ancestral inheritance than of
] convergent evolution. Many animals taste similar because
] they evolved from a common ancestor that tasted that way.
] The meat of our argument is that "chicken-like" flavor is
] ancestral (that is, plesiomorphic) for birds and many
] other vertebrates, as well. Indeed, the emphasis on
] chicken in the statement "tastes like chicken" is

] I therefore propose that the use of "taste like chicken"

] tetrapod."

Check out the "Taste Like" diagram at the bottom. This guy ate some seriously gross stuff for this study. Cat taste like tetrapod, in case you were wondering.

They also have an article that literally compares apples to oranges.
