[QUOTE]Originally posted by DD'eDeN: [QB] Modern Peanut's Wild Cousin, Thought Extinct, Found in Andes A new study reveals how two ancient species of this legume were combined 10,000 years ago, in Andean valleys, to create the modern peanut By Andrea Small Carmona on March 22, 2016 But where does it come from? Its origin seems to be in South America, specifically Bolivia, according to new studies. The modern peanut (Arachis hypogaea) is the result of the hybridization of two older types of Andean peanut. It has 20 pairs of chromosomes—the total from both old species, which have 10 chromosomes each. Scientists always thought—a suspicion now confirmed—that the "parents" of this peanut were the variants Arachis duranensis, very common in the Andean foothills between northwestern Argentina and southeastern Bolivia, and Arachis ipaensis, a species that had been reported but unconfirmed in a Bolivian town several hundred kilometers north, but thought to be extinct, until now. "We now know that the first inhabitants of South America in their long voyages carried A. ipaensis to the land of A. duranensis 10,000 years ago. Once in the same area, bees pollinized the peanut plant flowers, allowing the birth of the hybrid that our South American ancestors ate and that eventually led to the modern peanut, Arachia hypogaea. It's a fascinating story," says David Bertioli, a researcher at the Center for Applied Genetic Technologies at U.G.A. and lead author of the study, published in Nature Genetics. (Scientific American is part of Springer Nature). Although it has not been studied how old A. duranensis and [/QB][/QUOTE]
