Wow, the Daily Mail is reporting that over 150 human-animal hybrids have been grown in UK labs since 2008, the same year the Brits passed the Human Fertilisation Embryology Act allowing for this kind of research. For some reason these transgenic embryos have been produced secretively for the past three years.
Specifically, the scientists produced animal eggs fertilised by a human sperm, ‘cybrids’, in which a human nucleus is implanted into an animal cell, and ‘chimeras’, in which human cells are mixed with animal embryos.
The purpose of the research is to develop embryonic stem cells which can be used to treat a range of incurable illnesses.
It's worth noting that human-animal hybrids are also created in other countries, many of which have little or no regulation.
