Previous calls for an outright ban on all human-animal embryos outraged scientists, according to the article, who believe that 'work on human-animal hybrid embryos will greatly speed up progress in stem cell research.' The report claims there will be a provision for regulation of the research to incorporate any 'unforeseen developments.' Let the Island of Dr. Moreau comparisons begin!"
