Scientists in the United Kingdom have created part-human, part-animal hybrid embryos. Mermaids and centuars may be mythological but this is not science fiction; it's science fact. Because of the shortage of human eggs for the cloning process, scientists have turned to alternative egg sources: animals, namely cows and mice. The creation of a hybrid is documented as legal in the U.K. but it is an open book here in the U.S. Senator Sam Brownback and Representative Chris Smith have proposed the Human-Animal Hybrid Prohibition Act. This act would ban the creation, transfer, or transportation of a human-animal hybrid. Hybrid technologies degrade human dignity. And they could potentially lead to a subclass of human beings used for parts and treated less-than-human. The waters are murky. Furthermore, this experimentation would all be in the name of science, not patients. Mixing animal and human tissue and applying it to treatments could likely result in avian flu or other yet unknown cross-species disease outbreaks. We must ban this outright and from the outset.
