Texas School Board Searching For Alternatives To Evolutionary Theory
An anonymous reader writes "[Ars Technica] recently reviewed the documentary The Revisionaries, which chronicles the actions of the Texas state school board as it attempted to rewrite the science and history standards that had been prepared by experts in education and the relevant subjects. For biology, the board's revisions meant that textbook publishers were instructed to help teachers and students 'analyze all sides of scientific information' about evolution. Given that ideas only reach the status of theory if they have overwhelming evidence supporting them, it isn't at all clear what 'all sides' would involve."
May we each be touched by his noodley appendage!
Ever notice that Cobra Commander sounds an awful lot like Star scream?
Sigh. There's just no cure for stupid. Full disclosure. I live in Texas and yes, this embarrasses me.
Please do not read this sig. Thank you.
...or maybe a theorem. Or a rumor.
Maybe a wacky folk story.

Gravity is a very active area of theoretical study. We don't understand what it is very well, and there are strong indications that General Relativity is not complete, that we need a better theory to fully explain interactions, particularly on the quantum level.
You may be confusing the theory with the fact. The fact of gravity is that objects attract, or on a more human scale, that things fall down. That is something you can just observe, sometimes without meaning to. The theory of gravity is to explain how and why the interaction works. That one we don't have nailed.
Not trying to support Texas here in their unscientific bullshit, but gravity is not an open and shut case. What its method of action is, how it works on very small and large levels, and how it unifies with the other forces are still not well understood.
Lots of homosexuals procreate, lots of people who have abortions have kids. Abortion and infanticide may actually preserve a generational line in times scarcity, in that resources can be concentrated on existing children. Homosexual people procreate in heterosexual relationships all the time, and use IVF or surrogacy to procreate in homosexual relationships. The world is a little more complicated than you think.
Bullshit. You're equivocating for the same nonsense of the creationists.
This isn't true at all. You're redefining theory as the sole progenitor of hypothesis. You've got it backwards, there, chief.
The National Academy of Sciences lays it out for you:

It is incorrect that ideas only reach the status of "theory" when there's overwhelming evidence. A theory is a theory because it makes a testable, falsifiable, hypothesis. We have theories that aren't well tested. We don't go teaching them in science class, but that doesn't mean they aren't theories. This idea that "theory" means "proven beyond any reasonable doubt" is silly. It doesn't.
A hypothesis is a testable, falsifiable conjecture. A theory is arrived at by testing one or more hypotheses in a model and finding them not to be untrue. You are correct that there are theories which have not been exhaustively tested. The TOE is not one of those. A shitload of observations in many fields support it - or rather, do not support an alternative to it.

Evolution can't tell me what conditions to subject rats to so that I end up with something that isn't a rat.
Of course it can. You just have to understand that long term evolution is a macroscopic process resulting from changes in DNA. Increase the mutations, breed many generations, and expose those generations to selective pressure. It's really not that hard to understand. And "isn't a rat" is a fairly silly, non-scientific, though also easy to determine. The definition of a species is somewhat subjective, but generally is that members can interbreed and have fertile offspring. Change the rat's DNA so much that it can breed with other organisms with that change but not original rats and there you go.
And it can't tell me how many generations it'll take
That's an even sillier argument. Theories of statistics can't tell you how many tries it will take to get heads when flipping a quarter, but that doesn't mean statistics is not testable. If I told you I'd give you 1:10 odds (ie. you get $1 for a $10 bet) that the next coin flip is heads, would you take it? How about if I gave you those odds that over 1M coin clips the results are between 0.49 and 0.51? (Hint: you should take the bet. And that's a prediction).
And anyway it basically can tell you how many generations it will take - it will take as many as necessary to cause exactly the mutations needed to achieve the change you are looking for. You might be able to speed that up via mutagens and increased selective pressure, or once (it's only a matter of time) humans can trivially map the entire gene sequence and function for an organism and have the technology to modify them, it could be one generation (as it is these thing are already being done, just not as efficiently as they could). But it's all the same to the DNA.
Evolution can't tell me where to dig to find a creature whose bones are part way between a form believed to be a descendent of another.
Yes, it can. That's how so many of the existing bones have been found in a relatively small region of the world. Archaeologists didn't just dig billions of random holes around the planet and cross their fingers.
And it can't reliably tell me what those bones will look like when I do find them.
Seriously, just give it up. You don't even need to be a biologist to prove this statement wrong, 5 minutes on Google would do it. Sigh. Will there be the occasional surprise? Absolutely, because due to its underlying mechanisms some aspects of evolution are RANDOM. But if you think that disproves anything or discredits the theory, back to that coin flipping experiment for you...
do something about it
it's only like this because not enough texans like you are agitating about this
i would bet a majority of texans agree with you. the problem is a highly motivated, highly vocal minorty highjack the process and the majority is quiet and complacent about the whole nightmare
you need to get involved. you get the texas you deserve. so put some effort into it, kick these militantly ignorant morons off your school board, and restore texas to the modern world
intellectual property law is philosophically incoherent. it is your moral duty to ignore it or sabotage it
