Deadly Waters No Problem for Well-Equipped Algae
by Brian Thomas, M.S.*
Arsenic is a common toxic component in pesticides and herbicides, and one place it is found naturally is in the hot springs of Yellowstone National Park. The arsenic in the water there would be deadly to many living creatures, yet the Cyanidioschyzon algae thrive in it because they are specially equipped to detoxify arsenic through chemical modification. Some bacteria, marine worms, and lichens are also known to convert between different forms of arsenic, but new research details how the algae do it....

Oh no! - What ever are we going to do; they’ve burned the church down......
Instead of ooh-ing and ahh-ing over extreme -philes, how about looking up a little real research on them.

Small, compact genomes of ultrasmall unicellular algae provide information on the basic and essential genes that support the lives of photosynthetic eukaryotes, including higher plants. Here we report the 16,520,305-base-pair sequence of the 20 chromosomes of the unicellular red alga Cyanidioschyzon merolae 10D as the first complete algal genome. We identified 5,331 genes in total, of which at least 86.3% were expressed. Unique characteristics of this genomic structure include: a lack of introns in all but 26 genes; only three copies of ribosomal DNA units that maintain the nucleolus; and two dynamin genes that are involved only in the division of mitochondria and plastids. The conserved mosaic origin of Calvin cycle enzymes in this red alga and in green plants supports the hypothesis of the existence of single primary plastid endosymbiosis. The lack of a myosin gene, in addition to the unexpressed actin gene, suggests a simpler system of cytokinesis. These results indicate that the C. merolae genome provides a model system with a simple gene composition for studying the origin, evolution and fundamental mechanisms of eukaryotic cells.

The complete nucleotide sequence of the plastid genome of the unicellular primitive red alga Cyanidioschyzon merolae 10D (Cyanidiophyceae) was determined. The genome is a circular DNA composed of 149,987 bp with no inverted repeats. The G + C content of this plastid genome is 37.6%. The C. merolae plastid genome contains 243 genes, which are distributed on both strands and consist of 36 RNA genes (3 rRNAs, 31 tRNAs, tmRNA, and a ribonuclease P RNA component) and 207 protein genes, including unidentified open reading frames. The striking feature of this genome is the high degree of gene compaction; it has very short intergenic distances (approximately 40% of the protein genes were overlapped) and no genes have introns. This genome encodes several genes that are rarely found in other plastid genomes. A gene encoding a subunit of sulfate transporter (cysW) is the first to be identified in a plastid genome. The cysT and cysW genes are located in the C. merolae plastid genome in series, and they probably function together with other nuclear-encoded components of the sulfate transport system. Our phylogenetic results suggest that the Cyanidiophyceae, including C. merolae, are a basal clade within the red lineage plastids.

Or maybe the arsenic isn't toxic to them.
Thanks for the ping!
[[These results indicate that the C. merolae genome provides a model system with a simple gene composition for studying the origin, evolution and fundamental mechanisms of eukaryotic cells]]
Yup- mustn’t assume anythign otherthan evolution- It just couldn’t be deisgned that way- had to evolve- any other explanation is Heresy!
based on what.....?
Science is limited. It can’t answer everything. If you think it can then you simply have a different belief system.
[[Science is limited. It cant answer everything. If you think it can then you simply have a different belief system.]]
Tis true, tis true- but hten again “Nature did it” isn’t exactly a worthy attempt at a scientific endeavor- At least ID shows HOW IC is constructed and functions- the naturalist however jumps right in and ‘refutes’ IC by simply claiming ‘nature did it’ without ANY evidence to back it up. A classic example of this broad sweeping generalization by naturalists was the ‘explanation’ for how higher complexity blood clotting ‘could have’ arisen by ‘natural means’- Ken Miller went on to defeat his whole argument that blood clotting is ‘Reducible, and hterefore not irreducibly complex’ by inventing an INTELLIGENTLY DESIGNED scenario that nature simpyl is incapable of producing- His whole argument hinged on the idea that ‘Nature simply did it’ (somehow someway, but we just don’t know how by golly).
There’s another thread goign on right now about a dispute in ‘science’ where one camp thinks a hippo descended from whales, while another camp beleives it descended from pigs- Their only evidences? Homological similarities- they don;’t even attempt to answer hte scientific quesitons about the trillions of biological and morphological changes that MUST have taken place ‘sometime in the past’ apparently, for which there is NO scientific evidence to support- They might as well assume rocks gave birth to pomegranits concidering how little evidence they have to support their claims- and to boot- they can’t even begin to agree on which species the hippo allegedly descended from because there again, is infact NO scientific evidence to support the trillions of changes that MUST have taken place for which there simpyl is no evidence to show. Assumptions I’m afraid is not science- Evidence is science- ID presents evidence- Macroevolution leaves hte realm of science and wanders down the dark path of godless assumptions.
Sorry- but science doesn’t even begin to seriously TRY to answer HOW- all they do is htrow out a bunch of scenarios, and claim nature must have done it ‘in the past sometime’
Evolution and Christianity are perfectly compatible.
You have mistaken “evidence” with inept deconstructive criticism. ID shows nothing - not one thing has a so called intelligent design advocate ever proven. All that ID “science” (term used very loosely) does is stand in its little corner and sneer at real science.
Again I say - if you don’t know how popcorn works - you think its magic. Since you can’t fathom the complexities of biology - you throw stones at us biologists.
I’ve tried to engage in serious debate but all I’ve ever gotten is misdirected, misunderstood, half baked, web-generated, un-sourced hogwash.
[[All that ID science (term used very loosely) does is stand in its little corner and sneer at real science.]]
Says the sneererer!
[[You have mistaken evidence with inept deconstructive criticism.]]
I’m assuming you are refering to the inept ‘desconstructive criticism’ that Ken Miller presented? If so- then you are correct- He attempted to deconstruct IC but failed miserably- and simply proved, once again, that it takes intelligent design to construct the IC systems we know to exist- and by the way- all life is IC- right from the simpelst cells to the top species- look up ‘life’s irreducible structures’ in google, and you’ll find the FR thread that discusses this new metainformation problem that will prove to be evolution’s ultimate undoing.
[[Again I say - if you dont know how popcorn works - you think its magic. Since you cant fathom the complexities of biology - you throw stones at us biologists.]]
Lol- an amateurish attempt at subtle insulting- Step it up a bit- Say what’s really on yer mind- Shall I state that since ‘real science’ can’t explain how IC can exist, then they must therefore declare it magic, and that ‘nature did it’ ‘sometime in the past’? Because that’s the truth- they can NOT explain IC via naturalism, but insist ‘nature did it’ and that IC is an ‘illusion’! lol
[[Ive tried to engage in serious debate but all Ive ever gotten is misdirected, misunderstood, half baked, web-generated, un-sourced hogwash.]]
Says hte misdirecting, misunderstanding, half-baked, unscourced hogwasher!
[[Ive tried to engage in serious debate]]
No! You’ve presented assumptions, and htne complain and engage in name calling and thinly veiled insults toward ID when people ask for details- Character assassination isn’t ‘serious debate’- but do lemme know when you’re willing to step it up a bit, put aside subjective opinions, and discuss the actual evidences. When you’re willing to cede the gigantic gaps and assumptions in hte claims made- then we’ll engage in ‘serious debate’- but if all you’re goign to do is complain that I and others don’t accept the same a priori assumptions that you do without questioning the actual details, then whatever- but let’s not pretend there’s been any attempt at ‘serious discussions’ yet. You presented an article by talkorigins- a KNOWN deceptive website- I presented evidences which expose the wild assumptions made in the talkorigin’s claims, and you didn’t liek that- That isn’t ‘serious debate’ that is a case of ‘agree with me, or else I’m taking my ball and going home’
IF you want ot be taken seriously, then stick to facts, evidences, and we’ll discuss whether the conclusions on either side have more weight than the othe’rs conculisions do- I’m confident that ID holds more actual wieght, and that macroevo is really, when examined and broken down, a pastry puff with fluff filling. Woops- engaged in opinion.
Touched a nerve, have I?
I refer you to the articles I have linked above. They are not talkorigins - they are from japanese research biologists.
I will cede that you expect every little detail to be spelled out to you in minutia. Are there gaps in the knowledge base - yes. If we knew everything there would not be a reason to study anything. You assume that because not everything is explained that nothing can be. That is pure fallacy. And, not to correct you, but, you say you are not using an apriori assumption - again, that’s false. You’re assuming that everything that doesn’t fit into a bibliocentric worldview is false. I’m no amature but from your comments on this and many other threads I assume that your knowledge of science comes from the condemnations launched from non-scientific web sites. That’s poor logic, poor reasoning, and poor judgement if you presume to debate me.
Up a creek without a paddle? No problem. Hold our beers, and watch this!
Re-read my post.
Ok, I did.
There are several ways of taking what you wrote. I chose one.
[[Touched a nerve, have I?]]
It was my last nerve and I’ll be danged if you didn’t jump all over it- lol- No- no nerve touched.
[[I will cede that you expect every little detail to be spelled out to you in minutia.]]
‘Every minutia’? No- but I DO expect more than ‘nature did it- and that is that’
[[Are there gaps in the knowledge base - yes.]]
There arew not only gaps- there are impossibilities-
[[You assume that because not everything is explained that nothing can be.]]
Nope- wrong! It is explained- you folk however refuse to accept anythign but naturalism
[[And, not to correct you, but, you say you are not using an apriori assumption - again, thats false.]]
Nope it isn’t false- I examine hte evidence- when enough evidence is present to present a beyond reasonable doubt conclusion- that is NOT a priori- that is following hte evidence and coming to a reasonable conclusion- the natural explanation is NOT reasonable precisely ecause it violates scientific priciples and laws- but that apparently doesn’t bother those that think man came from goo.
[[Youre assuming that everything that doesnt fit into a bibliocentric worldview is false.]]
Bzzzzzt! Wrong! I see you don’t care to present any reasonable arguments- but rather apparently are content tryign to figure out what I beleive and why- but not to worry- I’m used to evasive lines of ‘arguments’ from anturalists- when you feel you wish to discuss the evidences, lemme know- huh? Till then- I’ll continue examining hte evidences objectively and seeing if they are possible via nature or not- so far I’m finding they are not
[[Im no amature but from your comments on this and many other threads I assume that your knowledge of science comes from the condemnations launched from non-scientific web sites.]]
That’s BS- You obviously have NOT looked at my arguments when hte discussions STAYED ON TOPIC and didn’t deviate into name calling and ad hominem attacks liek you seem to be devolving into- but again- I’m used to that little tactic because it’s apparent it’s the only ‘defense’ you folks have left.
