Human Language Gene Changes How Mice Squeak 185
archatheist writes "Researchers at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany have engineered a mouse whose FOXP2 gene has been swapped out for a different (human) version. This is interesting because the gene is implicated in human language, and this has changed how mice squeak. 'In a region of the brain called the basal ganglia, known in people to be involved in language, the humanized mice grew nerve cells that had a more complex structure. Baby mice utter ultrasonic whistles when removed from their mothers. The humanized baby mice, when isolated, made whistles that had a slightly lower pitch, among other differences, Dr. Enard says. Dr. Enard argues that putting significant human genes into mice is the only feasible way of exploring the essential differences between people and chimps, our closest living relatives.' The academic paper was published in Cell."
Where is the line? (Score:4, Interesting)
I'm assuming most people here won't have a problem with this research. But truly, where is the line? What about injecting human brain cells into mice? How about into chimps? Do we have any moral obligations not to cross this line? I am in awe and at the same time terrified about the future.
This article raises some of these questions. It's quite interesting that it was written in 2004. It even mentions the FOXP2 gene.

Suppose that this mouse is actually now sentient. Do we commit a crime when we imprison it in a laboratory or mangle its body (for the sake of some test)?

Cognitive linguistics suggests that consciousness is inextricably linked to language
A further study of slashdot posts suggests consciousness is linked to typing. You know we once had equally dogy and self serving reasons to believe that Africans weren't intelligent.

And the mice will suddenly start to develop extreme communication skills and figure out how to upset the results of the scientists.
This is an interesting part of science, even if it's not always morally "right". The outcome should be that we will learn more about ourselves and to design better drugs to treat illnesses.
But the more worrying kind of action here is that it also invites to tampering with genes that can make humans meek and controllable. A new level of slavery can be developed. Just imagine a totalitarian state with zombie slaves to do all the dirt work. If the Nazis had had this technology they would have used it! And super-humans that can exceed all current Olympic records.
Let's just say that we live in interesting times!

cognitive linguistics suggests that, but cognitive linguists can also assume that consciousness is an artifact of the networks languages organize our minds into. Speech is like a projection of the maps our minds use to organize stimuli, typing is linked to how we consciously view consciousness and then try to reorganize it into communication. It is not dodgy or self-serving, those old "reasons" were ad hoc methods to justify a conclusion, from a different hegemonic mindset. The dodgy part is that an inability to express a thought constitutes an absence of the thought - when in actuality, the expression of the thought is a fundamental component of the thought itself, as though thought is a component vector, and realizing the thought through speech (whether spoken or internally-articulated) is a necessary element. Consciousness is a speech act - everything else is some derivative of our reptile brain - arguably. Of course, that's just our particular mapping. YMMV

What I wouldn't pay for a mouse that could curse. Or good god a monkey. Give me a cursing monkey and I'll tithe you every paycheck 'til I die.
A marker of language as opposed to verbal signaling is that speech is 'productive'. That is, it evolves. This can be done by compounding -- simplifying multiple elements into a single one. An example of Koko the gorilla doing comes from Penny Patterson's dissertation. Koko took the signs for 'apple' and 'drink' and formed a single compound sign for 'apple juice'. This example has been passed around for years as good evidence Koko was actually using language.
Another example from the same source but not made as public was Koko's compounding 'dirty', 'toilet' and 'stink' into a sign referring to feces. Not terribly surprising in normal use. But she used it in another context. When her intended mate Mike was introduced, Koko didn't care for him at all. One time when Penny was trying to cajole Koko into accepting Mike, she said "Mike is a smart gorilla. I like Mike." Unimpressed, Koko replied "Mike dirty-toilet-stink", ie. 'Mike is shit'.
There's your cursing monkey (actually, ape). You can find it in her dissertation, "Linguistic Capabilities of a Lowland Gorilla", Stanford, 1979. Or you can call Koko's humans at 1-800-ME-GO-APE (634-6273), I dirty-toilet-stink you not. If you're serious about your paycheck to even the slightest degree, feel free to visit koko.org and donate to her Conservation Education Project: Koko is teaching sign language in Cameroon, to deaf children as well as to hearing children interested in becoming sign language interpreters. If anyone still doubts Koko's linguistic abilities in light of this fact, I would doubt their linguistic comprehension more than I would Koko's.

Why should we give equal rights to an animal just because it has a few human genes in it?
That's like giving a used condom the right to vote. The presence of human genetic material does not imbue some magical property on the animal or object which makes it suddenly one of God's Chosen Few (tm).
Luddite attitudes like that - people cowering in fear of accidentally doing something that they'd regret later - never accomplish anything of lasting value. The people who are praised throughout history are the ones who made a stir, whether they be Saints, scientists, or world leaders. As a species we admire the agents of change, even if we detest them. We may not approve of their actions, but we stand in awe of what they've accomplished.
If you as an individual are too frightened of a future in which people are touching the Magic Genome (tm) then there's a simple solution - don't take advantage of any of the fruits of current longevity research and die off before it becomes your problem. The rest of us will probably thank you - when you hold up progress in medical research because you have a moral problem with some guy diddling a mouse in a lab somewhere, you ensure that hundreds of people will die and thousands more will have a reduced quality of life due to the lack of the breakthroughs which may have helped them
They may not even be alive today. It may be somebody born tomorrow with a congenital defect who is the first beneficiary of this research. It might be your granddad or even yourself. Ethical treatment of test subjects is necessary, obviously, and we (the public) pay a higher price for research because of this need. But to suggest that the mere introduction of human tissue into a subject makes it eligible for equal human rights is magical thinking, and destructive to research.
