Are you a man or a mouse?

No really... "Animal-Human Hybrids Spark Controversy" is an article about the mixing of human stem cells with embryonic animals to create new species they are associating with chimeras—a hybrid creature that's part human, part animal. (chimeras—named after a monster in Greek mythology that had a lion's head, goat's body, and serpent's tail)
The article states, "Scientists feel that, the more humanlike the animal, the better research model it makes for testing drugs or possibly growing "spare parts," such as livers, to transplant into humans." and then it quotes, "One doesn't have to be religious or into animal rights to think this doesn't make sense... For example, an experiment that would raise concerns, he said, is genetically engineering mice to produce human sperm and eggs, then doing in vitro fertilization to produce a child whose parents are a pair of mice." Someone has already, according to this article, "created mice with brains that are about one percent human." and may later this year "conduct another experiment where the mice have 100 percent human brains."...
