Human-Animal Hybrids Fail 554

Posted by timothy from the good-help-hard-to-find dept.
SailorSpork writes "Fans of furries and anime-style cat girls will be disappointed by the news that attempts to create human animal hybrids have failed. Experiments by British scientists to create embryonic stem cells by putting human DNA into cow or rabbit eggs had raised ethical concerns, but the question of how we would treat sub-humans will have to wait until we actually figure out how to make them."

            See this relativist shit is too much for me. Inside every man's head (the sane ones) is a morality calling out that says "this is WRONG". Stop playing the "everything is gray" card because it's not. You live in a community and if said community says you should stop you either remove yourself completely from that community (good luck) or you comply. If you want to change the community views then so be it, but don't pretend for a second you live on some isolated island and have no contact with humanity so it's all OK as long as you stick to your own ethos. The community has a say also and has just as much right to "tell you what to do" when it comes to questions of morality. Morality is a social issue just as much as it's a personal issue.

      Seems to me the only time we resolve ethical concerns are when the ethical concerns become obsolete. People are still debating whether abortion is ethical. It comes down to a matter of beliefs. Does a human genetic code constitute an independant human? Your answer to that question, reguardless of how much you believe it, is not based on fact. Different people don't all share your beliefs and will have different answers. There is no resolving this ethics question. Well, there is one way, and that is to perform the science. If it turns out to be a scientific dead-end, then we'll have our answer: no it is not ethical because it's pointless.

      Note that I'm not saying lets do it BECAUSE it might be a scientific dead end and then we can move on, that would be a terrible reason to do something. Just pointing out that waiting for the ethical question to be answered 100% is basically a sneaky way of saying "lets not do this ever because I am uncomfortable with it."

    This has a lot of the same false problems that seems to plague morality based discussions of human cloning. The idea that a clone is going to be some sort of non-human entity with no moral standing one way or the other is just plain nuts. If you clone a person then that person has all of the rights any other person would have. It's really just a complicated way of giving birth. Even these human-animal hybrids are badly named, as they aren't going to be catgirls or manbearpigs or anything of the sort, just normal people with a really weird birth.

    The only time ethical concerns should really come into play is when you're attempting to convict someone of a crime based on DNA evidence, but it's not like the law has not had to deal with this sort of problem before. Identical twins have already generated plenty of precedents to draw from.

    It drives me crazy when congresspeople are spending hours and hours talking about how cloning is an affront before god and has to be stopped, but can't seem to make a good argument as to why other than citing bad movie plots or vague "They won't have a soul!" type arguments.

      There are a lot of cases where genetic engineering (either cloning or hybridization) DOES raise many valid ethical concerns.

      Think about this:

      1) Would you feel bad about taking organs from a clone which was grown without any brain?
      2) What about a clone who had a brain the size of a bird's?
      3) What about a clone with a brain the size of a three year old?

      Or say we made some humans who had the intelligence of a dog. Would they be less than human? Could we treat them like slaves and train them just like we train dogs now? What would happen if one of the subhumans bred with a real human? Would the result be 'human' enough that you would treat it like a human?

      Every ethical argument has some unjustifiable assumptions at its base.

      "We should maximize the sum of human happiness over time." But why?

      "Do unto others as you'd have them do to you." But why?

      "Let everyone do their own thing so long as it doesn't impinge on your own happiness." But why?

      "Respect the sanctity of human life, from conception through to death." But why?

      "Don't punish the innocent." But why?

      "All men are created equal." Really? Why do you think that? ('self-evidence' isn't a very solid ground in an argument.)

    It has been known for a while now that enucleating an egg (i.e. removing its nucleus) and putting the nucleus of an adult cell inside it seems to do somewhat of a reset. This makes a little sense, since mammalian eggs have chemicals and chemical gradients necessary to uncover the right genes to start off the process.

    Given how hard it is to get eggs from humans, other animals would be ideal.

    The thing is, the nuclei of these eggs are removed. There is one thing of the animals' genes that would remain, though: the mitochondria. That's why you can trace just your maternal line through your mitochondria - they are provided almost exclusively by the egg. If this ever gets used for actual cloning, imagine how this could screw up a deep ancestry project!

    Mitochondria do pretty much the same job and have done so for aeons. They do mutate faster, though, so there *might* be other jobs that they are doing for us that are slightly incompatible. On the whole, though, probably not. In the end, chances are that the only fantasy "hybrid" part of this is human cells with animal batteries.

    There's a lot of basic research left to do to see how cow and rabbit eggs (especially the ever-copious rabbit eggs!) differ from human eggs in terms of the chemical environment they provide, but once we figure that out, we will have another avenue of making stem cell equivalents, valuable for all sorts of things including spinal cord repair.

    Cloning is a little different than therapeutic stem cell application would be, however. You cannot just throw cloned 'stem' cells into a body - you will get a teratoma: a disgusting ball of flesh with all the body tissues in it. You need to coax it down other development paths first. You can wait for a cloned embryo to develop and take out that particular kind of tissue, which is where some ethical considerations come in, or you can apply hormones and other chemicals to do the job.
