The US Conference of Catholic Bishops have said that proposals by the National Institutes of Health (NIH) to authorise federally funded research on part-human, part-animal embryos are “grossly unethical.”

The bishops made ethical and legal arguments in opposing the plan in a submission to the institute this week, saying that such research would result in “beings who do not fully belong to either the human race or the host animal species.”

NIH has proposed funding scientists researching such embryos, known as chimeras.
Chimeras definition - (in Greek mythology) a fire-breathing female monster with a lion's head, a goat's body, and a serpent's tail. YES REALLY!!
