Cloning. What is stopping these companies from collecting random DNA on the street? Ethics? Morals? One can only hope.
I was thinking tonight about how we often leave our genetic material behind. Disposable cups, strands of hair traveling on the wind, cells deposited randomly from our shedding skin.
Cloning companies. Other than the very sick, dead, or attention whores, who else would volunteer DNA for this? Yet, the companies will still have to experiment to bring in the big money. At some point animals just aren't going to cut it anymore. So, pray tell where will they get the DNA to experiment extensively? A few cotton swabs and a sterile baggie later, and they could clone you. It's kind freaky to think about actually.
Food for thought.
