You may soon have to come up with a better definition. In vitro fertilization, cloning, surrogate parents, changing the DNA of a zygote are just the beginning. Soon I'll be able to take my DNA, put it into a pig's egg and have the pig deliver my baby. Not something I advocate but it will be technically possible. Is that baby human?Human biological parents.Every creature on the planet is a unique being. What makes a fertilized human egg different from the fertilized egg of any other mammal?
If the DNA of an organism is himan, it's fucking human.
How can you be so easily confused about that?
