The field of culinary evolution faces one great dilemma: why do most cooked, exotic meats taste like cooked Gallus gallus, the domestic chicken?
It is curious that so many animals have a similar taste. Did each species evolve this trait independently or did they all inherit it from a common ancestor? That is the burning question.
Using a diagram that shows how some kinds of organisms evolved from other kinds of organisms. This is a "tree" of evolutionary ancestry. Then the author and researcher created a tree using flavours of their meat to see if animals that taste similarly have similarly tasting ancestors.
