According to researchers, there is an interest in using increasing human material in animal experiments. A group of UK scientists has taken a proactive role in warning the government about future attempts to veer research towards:
“…three types of experiments that might soon become possible and would cause particular concern: modifying animal brains to mirror human “cerebral function”; fertilising human eggs or sperm in an animal; or endowing animals with characteristics perceived as uniquely human such as facial shape, skin texture or speech.”
In addition, another field of concern is one regarding making animals sound more like humans.
I, for one, would prefer to see some humans behave more like animals.
