No there is not, one just speeds up the process, when you starting mooing from eating hamburger you would be correct.
Are you saying there is no difference between selective breeding and the introduction of new DNA from another unrelated organism? Selective breeding does not introduce new genes from totally different species of organisms. The genes put into certain crops are not alwasy from related organisms. For instance, arctic fish genes when when put into tomatoes and strawberries gave them tolerance to frost, and human genes inserted into corn produced spermatocides.
Should we really be inserting genes from one organism into a totally different organism?
