Document Summary
Provides framework of where we are and where we"re going. Mankind has had implicit knowledge of genetics for a long time, but had no hard science or explicit knowledge the first genetic engineering began 10-20,000 years ago in the form of breeding plants and animals for desired traits. Wild onions, lentils, and ginger were engineered by humans, and replaced the original progenitor plants. Bricks & mortar approach thought sperm contained tiny body parts and transferred them to. Fertile ground" of womb where the parts assembled and grew. Believed in the inheritance of acquired characteristics characteristics which parents acquire prior to conception are past on to offspring. Example: strong olympic body builders pass on big biceps so their offspring are born strong olympic body builders. Example: giraffes that stretched their necks to reach leaves had offspring with longer necks. Example: father loses arm in war, but offspring has two arms.
