Peas have apparently been around for a long time....during archeaological digs they have been discovered in Egyptian tombs. No one knows for certain where the pea originated, but according to Chinese mythology, peas were discovered by emperor Shu Nung in 3000 BC. Shu Nung would scour the countryside in search of new plants in which to use for food or medicine. Shu Nung was considered the father of agriculture. Upon discovering a new plant, he would feed it to a dog first and then a servant. If they both lived then the emperor would eat it as well. (Sounds like russian roulette garden style.)
Did you know the garden pea has been used in genetic testing? I seem to remember studying about a certain fellow named Gregory Mendel in science class. Mendel is often referred to as the "Father of Genetics" for discovering the outcome of cross breeding different types of pea plants.
As for human genetics...you guessed it...the hippy chick photo is my darling granddaughter (Abby) She loves to peas out in the garden with her grandma :)
