In 2006, President George W. Bush shocked the world when he proclaimed in the State of the Union address that "creating human-animal hybrids" should be outlawed.
BUSH: A hopeful society has institutions of science and medicine that do not cut ethical corners and that recognize the matchless value of every life.
Tonight I ask you to pass legislation to prohibit the most egregious abuses of medical research: human cloning in all its forms; creating or implanting embryos for experiments; creating human-animal hybrids; and buying, selling or patenting human embryos.
Human life is a gift from our creator, and that gift should never be discarded, devalued or put up for sale.

Apparently Certain People didn't get the message. Scientists have now created human-pig hybrids.
Researchers reported Thursday in the journal Cell that they injected pig embryos with human stem cells that were capable of developing into a wide range of tissues. Those composite embryos were then transferred into the wombs of mother pigs.
By the time the scientists harvested the embryos after four weeks, the human stem cells had established beachheads throughout the developing pigs. As a blob of fetal pig tissue reached the cusp of developing into a cluster of distinct organs, human cells appeared throughout the tiny organism, ready to contribute to the generation of organs.
Each of these embryos held the promise of becoming a true chimera: a creature half-human, half-beast that has inspired myths and science fiction fantasies through the ages.

The domestic pig has long been seen as animal that could incubate replacement organs for humans. They are fellow mammals whose organs grow to about the same size as those of an adult human in the span of about two years.
But if the human immune system is to be tricked into accepting a pig’s organ, scientists know that human cells — in fact, cells specific to the transplant recipient — would need to be well represented in that organ.
