All domesticated plants and animal are neotinized versions of wild plants
and animals.  Neoteny is a type of mutation in which juvenale traits are
retained into adulthood.  Dogs are wolves who never grow up.  Grains are
grasses that never fully mature.  Domestic legumes are far different than
those found in Nature.  In a recent article in Current Anthropology
"Hominid Food Selection Before Fire" it is pointed out that they are
almost never eaten by Primates in the wild.

Domestic cows are much more similar to their wild counterparts than
legumes are.  They also contain less fat than mammouths, mastodons.
ground sloths and other Pleistocene animals we ate to death in the late
Paleolithic era a mere 350 generations ago.

Several books addressing neoteny may be found in the bibliography of
NeanderThin.
