Pig + Human Embryo

Biologist Pablo Ross at the University of California, Davis says. "We're doing this for a biomedical purpose."

What are they doing?   Making half animal and half human embryos - 'Chimeras.'  Then, the chimera embryos are implanted into the wombs of adult pigs.

Ross says, "If a male chimeric pig mated with a female chimeric pig, the result could be a human fetus developing in the uterus of that female chimera," ultimately giving birth to some kind of part-human, part-pig creature.

Ross reassures not to worry he has it all under control.   Sure he does.
