Sometimes I Feel Like a Fatherless Mouse....
I was going to entitle this post "Lesbian Babies: No Men Required" until my more musical wife gave me the more musical title. A Japanese geneticist has succeeded in producing live mice with the genetic material from two female mice, something previously thought impossible. Though, as visionary Arthur C. Clarke once put it,"If an elderly but distinguished scientist says that something is possible, he is almost certainly right, but if he says that it is impossible, he is very probably wrong."
It wasn't easy: he created over 450 embryos, of which only ten produced live births and one lived to adulthood. And in order to make the genetic material come together, he had to create a new strain of mice whose female genetic material had some missing elements that made their DNA more masculine. And there was some pretty sensitive chemical manipulation of the eggs and DNA to bring the DNA together and keep it from falling apart.
This isn't for human application. A couple of lesbians can't go down to a fertility clinic and produce a child that really is equally theirs. Not yet, anyway. And there's a couple more steps to go through before a dual-male offspring is possible (and, as my wife pointed out, since you need an egg, even with the nucleonic DNA removed, there's still the mitochondrial DNA, which means that the child would be a very small part related to the egg donor) and there's still the problem of carrying the child which isn't yet possible for males.
But the science is proceeding. Someone will refine the process so that the success rate increases. And someone else will refine the process so that DNA from an unmodified pair of female mice can be used. And someone else will refine the process for higher-order mammals: the researcher responsible for this, Tomohiro KONO, is going to try pigs next, which is a genetic single step from humans for most purposes. Then someone will try it on humans. And eventually, they'll succeed. Don't think that a Republican-controlled Congress will stop them, either, because if we make interesting research illegal in this country, it'll just happen elsewhere: this pseudo-parthenogic mouse was produced in Japan with Japanese funding.
Then what? Well, for one thing, the procreative argument against same-sex marriage goes out the window. There are some Christians who are already moving it towards the door [scroll down to"More Thoughts on Marriage"], but anyone who was using a biological or evolutionary argument pretty much just lost.
What else? Well, the human species has an evolutionary opportunity: no longer will we be limited to matching male and females for breeding purposes, and it increases the likelihood of good, bad and just plain interesting genetic results.
What else? Well, as I've said before, we have an ethical discussion ahead of us, and we have to decide if we're going to have it now, when we have time to think things through, or later, when we don't.
