Juan Carlos Izpisua Belmonte had spent years probing the inner workings of embryos, ferreting out the genes that give a body its shape or allow wings to form instead of legs. He’d tracked wafting chemical messengers that, like traffic police, guide streams of dividing cells either left or right. He’d even found a way to tweak animals to grow extra limbs

Julian Savulescu writes, “Scientists in the United States are creating so-called “human-pig chimeras” which will be capable of growing the much-needed organs. These chimeras are animals that combine human and pig characteristics. They are like mules that will provide organs that can be transplanted into humans.”
