Document Summary
The nobel prize in chemistry 2008; osamu shimomura, martin chalfie, roger y. tsien. He said that there"s dna on the environment, and they search out dna and hoard these. They"re trying to find something they can use--it"s like flipping a deck. Sometimes it gives it an advantage, like accelerated evolution. They can pass off the dna to their offspring. Strawberry kind won"t affect tomatoes, because it"s got that strawberry-specific dna. E. g. in europe, a fungus went to wheat. A professor could show the exact year, 1972 or so, that it happened (by seeing what was grown, etc. We can trace where the fungus is and how it is because it glows. We don"t know 80%-90% of our genome. Usually when something goes in, it makes a mutation. You can do that 50,000 times, and only 1 instance did it take. This is how diseases come out--it"s either environment, or new genetic genes!
