Scientists have created more than 200 human-animal hybrid embryos inlaboratories.
The hybrids have been produced secretively over the past years by researchers looking into possible cures for a wide range of diseases.
Scientists say the techniques can be used to develop embryonic stem cells which can be used to treat a range of incurable illnesses.
‘The problem with many scientists is that they want to do things because they want to experiment. That is not a good enough rationale.’
