The law does not define what is human, other then by the generic description of "homo sapiens" How about a fully artificial set of chromosomes from a computer database created in a lab? Without a VERY clear definition of human, that we currently don't have, these type of laws are useless. Is someone with downs syndrome human? they have a extra whole chromosome. How about someone who gets infected with a retrovirus. They now have a mix of human and virus DNA. How about people who are XXY, XXYY, XYY or other sexual genetic abnormalities? We share a LARGE portion of our DNA with everything from monkeys, dogs, mice, insects and even flowers. First define "Human", and by then many humans will be mixed with "animals" to make the laws worthless and conflict with the bill of rights along with many other laws. People, mostly the very religious, just don't want the understanding that "human" is just another kind of specialized animal.
