Article on Human-Animal Research
There’s an extensive AP story today (I read mine in the San Jose Mercury News) about mixing human cells with animals in stem cell research and concerns that people have about possibly “humanizing” animals or creating chimeras (animal-human hybrids). One researcher, for example, is trying to grow embryonic stem cells inside rabbit eggs so as to eliminate the need for egg donors. He has not succeeded thus far. It’s old news to put human cells inside mice, but some researchers are putting human cells inside animal brains, and that is causing concern. The scientists doing it say that it is biologically impossible for the cells to become human brains, given the shape of the animals’ skulls, the way their existing brain and nervous system functions, and so on. Human cells have also been successfully grown in goat embryos.
This is not something I wake in the middle of the night scared about. If there were a chance that a human could be made out of an animal, that would be bad—but none of the researchers are anywhere near that, nor are they trying. Will there be human genetic engineering at some point? Probably. Will it be unethical? That depends.
My neighbor bought nine chicks this spring to raise for eggs. They have an open run space of about 20x15, and most of them are active, clucky, and happy. Two of the chickens, however, have huge breasts, waddle around, and spend most of their time sitting and looking rather uncomfortable. They can’t even fly up to a roost. They were bred to be eaten, not to lay eggs. They do not act or look like normal birds. Creating monsters for human use has already happened. You might have one for dinner tonight.
