Document Summary
Most of human history and history: selection through careful breeding over many generations. Due to selective pressure corn became the way it is today (so many varieties and changed since beginning) Agricultural scientists can no splice genes from one organism into the dna of another organism for novel characteristics (total alteration in a single generation) Green revolution- people in india were starving so we needed to do something. All they are eating is rice but not getting all the nutrients they need. Genetically engineer rice to have beta carotene. Fortifying food by breeding crops to increase their nutritional value (one type of genetically modifying crops) Gmo crops are developed (many) to increase yield- main purpose of green revolution. Ex. , in britain it was illegal to genetically modify. Most of the anti-gmo fervor revolves around hypothetical concerns about human health. Ex. , using peanuts to modify a crop and then creating an allergy but little to no evidence that they are hazardous.
