Ok with out touching the evo v creation deal I will attempt to touch on genetic tampering for cosmetic purposes.
Genetic tampering to better human life in the way of food production or medical research. Imagine the out come of being able to replace organs with OEM part so to speak. Right now people that receive organs must take meds for life in order to keep the body from rejecting the organ. Think if you will people being able to receive a liver or kidney or cornea that is theirs not from another person. No rejection or meds it would be great. To also be able to fix congenital problems in children like MS and so on would be a huge step.
Genetic tampering for the sake of having a cool pet is a pointless waste of time money and resources in my mind. Now true some great discoveries may be made in the process but the chances are slim. Glowing pigs, rabbits, cats, hot pink ball pythons maybe one day but lets use the knowledge to better the creatures that will benefit the most from this us.
