Humans are the second least genetically diverse mammal species because , according to our DNA, we are all related to the less than 1,000 humans who survived the Pleistocene Extinctions about 70.000 years ago.  Only Cheetahs ( one pregnant female 7,000 years ago) are less genetically diverse.
 
This makes all of us at most 11th cousins!  Chimps ( total population less than 100,000) are far more genetically diverse ( take that D'Adamo).
 
Just because a food doesn't make one violently ill immediately doesn't it won't get you in the end.  Goober Peas, like all legumes, contain neurotoxins ( the origin of the character on "Goober" on The Andy Griffith Show) and are also very high in aflatoxins ( resulting in the fastest growing cancers in the US - pancreatic, liver, and esophageal - thank you Jimmy Carter).
 
Potatoes produce acrylamides  (90% of carcinogens found in human bodies)  at 140 degrees Fahrenheit.  Potatoes are also very high in a lectin that inhibits vitamin A uptake - recently a leading cause of blindness in the world.
 
Other tubers such as carrots, radishes, onions, etc are edible raw and thus perfectly fine.
 
You cannot breed a lab mouse in 300 generations (the time since the Neolithic Revolution), about 20 years of mice, whose immune system can tolerate a food not edible to any other species of Rodent!
 
Reindeer (another ruminant similar to horses in diet) have often been observed eating lemmings.
