Many different factors caused the project to take less time than initially planned, not the least of which was clever algorythmic techniques to speed up the decoding process. All of them combined led to a quicker result.

I believe you meant "basic" research rather than "pure" research. Basic research (as opposed to "applied" research) is "experimental and theoretical work undertaken primarily to acquire new knowledge without a specific application in view". There has been a general decline in spending on basic research by corporations in recent years due to the high cost and uncertainty of return on the investment, leading to the shift of basic research to universities. This has had good and bad effects on universities, who have benefited from the funds but have also found increasing limitations and restrictions placed upon them by their corporate sponsors. For example, there have been well documented reports of drug companies putting restrictions in grant contracts to public researchers preventing them from telling the public of any hazardous effects of their drugs, even when those same drugs are in current use by the public.
So their is no black or white answer to which is better, public or private research. Perhaps it is good to have both, just as it is good to have a multiplicity of competitors in a market economy. It may just help to keep everyone honest.

See, this particular subject has a special fascination with me. I'm always surprised by what various cultures do and don't eat. Somewhere around the world, you can find somebody who will eat any creature that has enough mass (or that exists in sufficient quantities) to make it worth their while. For example, in America we never eat horsemeat-- we feed it to our animals-- but in France and Belgium it's considered a delicacy. I've had horsemeat-- it's often prepared like lamb or mutton-- and found it to be quite delicious.
I think every animal is tasty. It's just a question of finding a group of people who think it's okay to eat it.
(Of course, the rules change completely when you talk about plants. We can't eat most plants, simply because our digestive system isn't set up for it. We have to eat heavily processed plants, like flour made from grains; juvenile plants or plant by-products like fruit; or plants that have been specially bred over the millennia to be perpetually juvenile. If you were to just go out and grab a handful of good old Kentucky crabgrass, you'd find it to be a memorable meal, but not one you'd long to repeat.)

I was counting plants, fungi, and single-celled organism, most of which are probably not tasty. Most of these produce exciting chemicals that our bodies are not equipped to handle. Some species make these chemicals to avoid becoming salad, others as part of their metabolic processes.
I will grant that most animals would probably be tasty if you can get over the "ick" factor. I expect the only non-tasty animals would be the ones who produce poisonous or bitter-tasting chemicals specifically in order to be non-tasty.
Heck, I expect even worms would be tasty, properly prepared. Just about everything else we use as fish bait is (other fish, squid, clams, crawfish, rolled-up bread, etc).

Ah, quite the contrary. It's my (imperfect) understanding that the rate of speciation goes up when resources are limited, and goes down during times of plenty.
The theory is that differences in individuals aren't sufficient to lead to speciation until they become survival traits. In a lush environment, individuals with all sorts of different characteristics can be equally successful. But in a more constrained environment, different traits become survival factors, and individuals with specific survival traits will tend to interbreed, leading eventually to speciation.
To use a really simple example, imagine a grassland populated by browsing mammals. The population is stable, the food and water sources are plentiful, the predation is low. Now kill off all the grass. Most of the browsing mammals will die off immediately. Some of them will have the (probably recessive) trait of being able to eat something other than grass; tree bark, maybe. Those individuals will survive and interbreed. Another group of the browsers will have the recessive trait of being able to eat dead browser. Those will survive-- thrive, even, given all the handy dead browserbeast carcasses lying around-- and interbreed. Eventually the two varieties of ex-browsers will drift far enough apart that they can no longer breed to produce fertile offspring. They'll become different species.
That's the theory, anyway.

Well, turns out that most of the reef damage in the area was caused by tropical storms. Hey, great. Good to hear. Of course, there was a whack of damage caused by fishermen using nets, poorly placed anchors, and cyanide, amongst other things. There was also a lot of damage from snorkelers, many of whom (heh) could not swim, and felt the need to stand on the coral where possible. There was also the dedicated work of the conservationists who, in trying to kill every crown-of-thorns starfish (that destroys reef) either created many more in some cases, or destroyed reef while destroying the starfish.

Well, we know almost nothing about how speciation occurs, but one can make estimates of the rate. If there are 10 million species today, and almost all of them evolved within the last million years, then the rate is probably ten per year, give and take an order of magnitude.
This numbers also illustrate that new the number of new species are not really relevant within this time frame. If 100 or a 1000 or 10000 new species form within the next ten years is of little consequence to a project aiming to categorize 10 million species.
One caveot to all this is that in reality speciation is probably not linear but rather happens more like in bursts. To your point, that would indicate that if we are in the middle of such a burst (which I never have heard suggested, btw) then sure that could mess up our calculations.

Besides, upon further reflection, wouldn't any project like this necessarily run up against a sort of Heisenberg effect? In order to be absolutely certain that you have catalogued every species on the planet, you have to examine every organism on the planet. Single-celled organisms, too. And examining a single-celled organism on the genetic level would necessarily result in the destruction of that organism. Practically speaking, this would happen with any microscopic organism; we simply can't learn about them without squishing them to see what goo comes out.

I think the idea is to identify species based on a genomic fingerprint- the usual marker is actually the sequence of 16S RNA (part of the ribosome). They simply collect as many samples as possible and feed them into the sequencer, and then use computers to determine the relationships.
At least that's what I assume from the article. I don't really think this is worthwhile, because it's easy for two organisms to be nearly identical on the sequence level and still be non-mating. You could have a single polymorphism be the only thing separating two species simply because of change in color, metabolism, etc., coupled with reproductive isolation. In particular, 16S RNA is used for large-scale cladistics because it changes relatively little over time, but this means that the difference between an Amazonian Spotted Yellow Frog and an Amazonian Spotted Green Frog may be nil at that level.
If they're looking at entire genomes, on the other hand, the technology simply won't be powerful enough for some time, particularly if they run into weird or huge genomes.

And theoretically even if a species goes extinct, if we've got the genome we'll eventually be able to resurect the species later, at which point scientists can do all the research on it they want.

As for the reliability, that would be a concern, but not as big a one as you make out. How many people would want to make up fake species? And could do so convincingly?

Here [orchids.mu] is a list of genera, including what they call them when they are intergenus crosses (and just for the letter "A"). If you take the genus "Allenara", it is a hybrid of the naturally occuring genera Cattleya, Diacrium, Epidendrum, and Laelia. You get a cross of four genera by making two hybrids (say Cattleya x Diacrium and Epidendrum x Laelia) and then crossing the two hybrids.
Maybe that definition will work for most things, but it's a mystery to me how they decide that this orchid is a different (or the same) species from that one, much less that they should be in different genera.

I see your point. Another poster already pointed out that my definition can't even be applied to asexual organisms, so it was dead before you even came along. Good info, though, about orchids.

In othe words, your definition is flawed because it assumes that species are static, whereas they REALLY are always in the process of splitting into multiple species. Plus, there's that time thing. A species not only has to be able to be classified solidly in today's environment, but it also needs to have a set classification that spans time so that we can deal with paleontological species as well. And since you can't mate two Tyrannosaurus skeletons and see if they produce viable offspring...well, I'm sure you get the point.

The lack of a definition for "species" is a problem for humans who like definitions, not for nature, which doesn't care if things become hard to define.
Some things, like pornography and race, are just not easily definable. Usually people use the standard of recognition (i.e. "I know it when I see it") which works well enough for most purposes.

At the risk of going offtopic, here goes. :)
The problem with this standard is that it only works on an individual level. Take love, for example. The most common definition of love that I've run across is "You'll know it when you feel it." Using this definition, I have seen quite a few couples get together and then get un-together because their definitions of love didn't mix. Each one knew that they loved the other, but the other didn't live up to some standard.
The reason this type of standard of recognition can't be used in science is because it depends on an individual viewpoint, and one of the fundamental principals of science is duplication. Without being able to duplicate somethign (research, observation, experimentation, etc.) with predictable results, then you can only continue to observe without concluding. When it comes time to conclude, your conclusions must be able to be duplicated by other scientists with completely different viewpoints (or worldviews, if you prefer).
To save a lot of digging. (Score:2)
When the next dominant species emerges from the sludge and reaches a stage where spaceflight is possible then they can just pick one up.
Then all the archaologists in the new species can down tools and start working on more forward looking matters, such as working out new ways to kill each other en-mass.
Wash, rinse, repeat.

Most conservation efforts start with identifying what's actually present inside an area. For a few groups such as birds, mammals, and butterflies, we have a pretty good knowledge of who's present, despite the occasional deer being discovered in Vietnam or the ten or so new bird species Peru has reveiled over the last few years. But in most groups, which actually account for 99% of biodiversity were are at a complete loss. So much for making sound judgements on where to make the next National Parks.
In order to know how much biodiversity actually needs to be preserved to for instance keep speciation going, or to keep extinction at a minimum, we have to get some basic insight into current state of affairs. Again, just knowing what species you're dealing with is a prerequisite if you want to obtain a global picture.
So from a practical point of view, completeness of the database is not essential. Getting our working knowledge of species from 1% to 50% would be a great step forward, and would probably be enough to obtain much better estimates of extinction rates.
As to how to even get DNA from all those millions of species, most of which have such small ranges and thrive in low numbers in inhospitable places, I can't say I have much of a clue either.

This sounds suspiciously like "playing God". If that is the case, then carry on.

I'd be cautious about doing the DNA testing though - I don't know if your gear will freak out at a triple helix strand.

BTW can i patent myself, more specifically my dna? So that if it is found that i carry some weird mutated form of a gene that cures cancer or something similar, i will make profit off the use of such a gene to help other people.
Actually, I thought the only useful purpose of patenting your dna was so you could sue your kids for infringing your patent when they have kids of their own, or something like that.
But due to the short life of a patent compared to the realistic ages at which people seem to be reproducing these days, it seems like an unrealistic use to put a patent to.
