Scientists have created embryos for the first time that are part human and part monkey, according to a new study.
"Nobody really wants monkeys walking around with human eggs and human sperm inside them. Because if a monkey with human sperm meets a monkey with human eggs, nobody wants a human embryo inside a monkey's uterus," said Hank Greely, a Stanford University bioethicist.
The team studied the embryos for 19 days to gain insight into how human and animal cells communicate, with the aim of one day discovering how to grow organs in animals that can be used for human transplantation.
