Scientists warn against creating human-monkey HYBRIDS as calls rise to create the chimeras

Experts are warning against the creation of hybrid lab animals for fear of causing them undue suffering through potentially unethical research. One such proposed hybrid would be monkeys with partially human-derived brains. These'chimeras' -- so named after the mythical beast made of different animals -- could let us better study diseases like Alzheimer's in a model more like humans. Chimeras have already been created to explore the possibility of creating transplantable human organs in animals to relieve donor organ shortages. And recently Chinese researchers reported creating the first monkeys with human brain genes.
