Speed Limit To Pace of Evolution, Biologists Say
Researchers at the University of Pennsylvania have developed a theoretical model that informs the understanding of evolution and determines how quickly an organism will evolve using a catalogue of "evolutionary speed limits." The model provides quantitative predictions for the speed of evolution on various "fitness landscapes," the dynamic and varied conditions under which bacteria, viruses and even humans adapt.
Oh, the humanity!
Comfort's article defending his asinine version of The Origin of Species (legitimate version pictured right) has been run at the U.S. News & World Report alongside a rebuttal by Eugenie Scott. Next week we can look forward to an online debate between a NASA Aeronautical Engineer and a four year old boy who thinks the lighting bolt stickers on his Hot Wheels make the cars "go faster." If my metaphor is unclear, the four year old is Ray Comfort, and no, I do not think the comparison is unfair.
Just for fun, let's take a brief look at what they have to say. We will start with Ray.
Why are many atheists so angry? Why are they talking about book burnings, threatening to resist the giveaway and rip out the Introduction, etc.? Why was richarddawkins.net encouraging people to collect copies and rip out the Introduction? Professor Dawkins himself said that even though "a lot of people seem to be very worried about this," he wasn't at all worried. Why did he then tell Toronto university students to tear out the Introduction? There have been more than 140 different editions of On the Origin of Species, many with special Introductions, so what's the big deal with this one? If I am (as Professor Dawkins says) "an ignorant fool," why are so many feeling threatened by what I've written? Surely, the Introduction will be ignorance and foolishness, and simply confirm the students' presuppositions that intelligent design isn't worthy of even a first look.
People are being encouraged to rip out your introduction, Ray, because without it they will be left with an historically relevant account of the initial formulation of Evolutionary Theory by the man who conceived it. I dare say you have never changed the mind of any person reasonably well educated in Evolutionary Theory, and since your arguments never change or evolve *gasp*, we can rest well assured that your introduction will be as baseless and stupid as every other argument you have ever made. Unfortunately, we live in a society that readily embraces willful ignorance and some may be swayed by your particular brand of foolishness. These people will then go on to vote and lobby against academic progress and continue to interfere with the work of legitimate intellectuals. Stupidity is dangerous, and that makes you a WMD.
The problem when arguing with those who believe in atheistic evolution is that they move goal posts by redefining atheism or evolution or the word species. From Darwin to Dawkins, they speak the language of speculation, continually using words like probably, maybe, perhaps, and could've. And Darwinism is as nebulous as a puffy cloud on a hot windy day, forever moving, changing, and expanding—because its bounds are limited only by the fertile human imagination.
The fallacies of equivocation simply never end with this man. He has been told over and over again that atheism and evolution are not one in the same, and he simply refuses to listen. That makes him a liar. I also love his tirades against the supposed "language of speculation" which just so happens to be the language of intellectual honesty. Mr. Comfort would not know anything about that.
When we give away On the Origin of Species to university students, I want every one of them to make sure they don't stop at the Introduction. I want them to thoroughly read On the Origin of Species. When I read the book, I was very impressed with the brilliance of Charles Darwin. If he was alive today, I am sure that he would quickly rise to the top of Disney's imagineers or earn big bucks as a Hollywood screenwriter for science-fiction movies. Among other things, Darwin noted that black bears swam for hours with their mouths open, catching insects in the water. He believed that if they kept their mouths open all day, every day (for a long period of time), that they would acquire "larger and larger mouths, until a creature was produced as monstrous as a whale" (Chapter Six, "Difficulties on Theory").
The irony! It burns!
There is far more abject idiocy in the remaining article, so read it in full at your own risk.
Okay, Eugenie, bring us out of this pit of despair before we drown in its sweltering pool of inanity.
Unfortunately, it will be hard to thoroughly read the version that Comfort will be distributing on college campuses in November. The copy his publisher sent me is missing no fewer than four crucial chapters, as well as Darwin's introduction. Two of the omitted chapters, Chapters 11 and 12, showcase biogeography, some of Darwin's strongest evidence for evolution. Which is a better explanation for the distribution of plants and animals around the planet: common ancestry or special creation? Which better explains why island species are more similar to species on the mainland closest to them, rather than to more distant species that share a similar environment? The answer clearly is common ancestry. Today, scientists continue to develop the science of biogeography, confirming, refining, and extending Darwin's conclusions.
Likewise missing from Comfort's bowdlerized version of the Origin is Chapter 13, where Darwin explained how evolution makes sense of classification, morphology, and embryology. To take a simple example, why do all land vertebrates (amphibians, mammals, and reptiles and birds) have four limbs? Not because four limbs are necessarily a superior design for land locomotion: insects have six, arachnids have eight, and millipedes have, well, lots. It's because all land vertebrates descended with modification from a four-legged ("tetrapod") ancestor. Since Darwin's era, scientists have repeatedly confirmed that the more recently two species have shared a common ancestor, the more similar are their anatomy, their biochemistry, their embryology, and their genetics.
Oh, she called you on that one, Mr. Comfort. I guess when you said you wanted college students to read the work you full, you meant you wanted them to read the work minus some of its most convincing evidences. Is not there a command in the Bible against bearing false witness? I seem to remember it was part of popular list of ten things YHWH does not want you to do.
It's not just human evolution that Comfort misrepresents. His main gripe is the old creationist standby, the supposed lack of transitional forms in the fossil record. (Darwin addressed the objection in Chapter 9 of the Origin, interestingly not included in Comfort's version.) Comfort sneers at the fossil evidence for the terrestrial ancestry of whales and the dinosaurian ancestry of birds. Too bad for him that he has a knack for picking bad examples: There are splendid fossils of dinosaurs that have feathers and of whales that have legs—and even feet. Faced with ignorance like this, I'm reminded of a jeremiad: "Oh foolish people, and without understanding; which have eyes, and see not; which have ears, and hear not."
But if you are willing to use your ears to listen to what paleontologists say about transitional features and use your eyes to look at the evidence described in the scientific literature (as well as displayed in many museums and science centers around the country), you will find transitional fossils galore. There are clear transitional series from aquatic vertebrates to land vertebrates, from primitive land vertebrates to mammals, from dinosaurs to birds, from land vertebrates to whales, and of course a wonderful series of fossils leading to Homo sapiens. A good place to begin is a marvelous website dismissively mentioned (and erroneously described) in Comfort's introduction, the University of California Museum of Paleontology's Understanding Evolution.
If you will pardon the common vernacular, thank god for Eugenie Scott. Ray, I hope you are enjoying your Golden Crocoduck.
Today on NASA-TV I watched the successful launch of the Aries 1-X Rocket's test flight. It went beautifully. Future versions of this rocket will help send our astronauts back to the Moon and onto Mars(and points beyond). Thought others of you interested in Space Flight and the on-goings of NASA would like to see this as well, if you missed it earlier today.
Here's the link to the official site at the NASA home page: Click me. And an excerpt:
Outstanding teamwork was the theme of the Ares I-X postlaunch news conference as the successful flight test was discussed.
"I can't say enough about this team," said Doug Cooke, associate administrator for the Exploration Systems Mission Directorate at NASA Headquarters in Washington. "They've been together probably a little over three years now, and they went from a concept to flying this vehicle in that period of time, which is the first time this has been done by a human spaceflight team in a long time."
Referring to the weather, which was the only issue of the day, Constellation Program Manager Jeff Hanley said, "We were ready when Mother Nature was ready, and we took our opportunity and what a great outcome. We're very proud of the result."
"It was a spectacular day," said Bob Ess, Ares I-X mission manager. "The vehicle flew even better than we expected."
"It is just a fantastic day," said Launch Director Ed Mango. "The team really excelled. I can't say enough about the folks who worked together to go make this thing happen. It was a great team, and as you can tell, it was a great vehicle."
NASA's Ares I-X test rocket lifted off at 11:30 a.m. EDT Wednesday from NASA's Kennedy Space Center in Florida for a two-minute powered flight. The flight test lasted about six minutes from its launch from the newly modified Launch Pad 39B until splashdown of the rocket's booster stage nearly 150 miles downrange.

Until next time...

We live in an age on the verge of tribulation. At least, that is what seemingly countless individuals keep telling us. From all sides we are bombarded with warnings of imminent doom from 2012ers, Nostradamus alarmists, whack job cultists, and the less than fringe fundamentalist groups who, like every generation before them, thinks the world will end within a few decades. Now we have a new group fearing a pending apocalypse, and they point to the Large Hadron Collider as the culprit.
To begin the search for an answer, I return once again to Skeptic Magazine (and yes, this is the second time in the span of a few days I have referenced the most recent issue). This month's issue includes something of a debate between Lloyd B. Lueptow and Lawrence Krauss, with Lueptow presenting a long argument in favor of caution, and Krauss offering a short rebuttal. Importantly noted are the qualifications of each in commenting on this topic: Krauss has degrees in mathematics and physics and has received awards from the American Physical Society, the American Association of Physics Teachers, and the American Institute of Physics, while Lueptow is someone presumably with a degree in something, as I could find extremely little information on him outside of a book he wrote. (From the context of the articles, he is evidently a sociologist.)
Lueptow's argument is very basic: we do not know enough about physics to adequately predict what will happen. He points to several conflicting hypotheses regarding what will ultimately happen when we collide protons at such high energy states, each of which could result in a doomsday scenario.
- Miniature black holes could form which would grow too rapidly and ultimately consume the earth within a few years. He rejects the consensus that microblack holes will dissolve stating we have no empirical reason to conclude such a thing.
- Strangelets, a theoretical particle, could emerge and begin a chain reaction that will convert all matter on earth into strange matter.
- Vacuum instability, a phenomena he admits is complicated and difficult to discuss, could result from these collisions and ripple outward changing the very nature of the cosmos itself.
Throughout the article, Lueptow quotes many scientists in an attempt to demonstrate that they disagree at what level of risk we are operating when we turn on the LHC. He believes we need more time to discuss the science, and that the scientists need to make their predictions and debates public so that we may be more informed. He then expresses the sentiment that the LHC should not be used unless scientists are highly certain the likelihood of catastrophe is very near zero.
Krauss, on the other hand, is highly dismissive of Lueptow's concerns. He argues that Lueptow's proposed approach to science would bring discovery to a veritable standstill, as all new experiments always deal with the unknown on some level. He furthermore argues that science is based on facts and observable data, so attempting to approach science within a democratic framework is fallacious. Despite that fact, he then points out that he has yet to encounter a scientist qualified to comment on the experiment who thinks any real danger exists and specifically states that while the men Lueptow cites may be brilliant, they are not experts in any fields pertinent to the LHC, namely particle theory, quantum gravity, and general relativity. High energy collisions occur as natural phenomena anyway, he claims, even though Lueptow rejects this proposition. Additionally, Krauss points out that smaller scale collisions have been going on in laboratories for quite some time; the LHC simply ups the ante. "We need to keep an open mind," says Krauss, "but not so open our brains fall out."
So which side do you fall on? You can probably guess what I think. Fire that bad boy up! The potential for discovery is massive. Some think the LHC may ultimately provide evidence supporting string theory. If microblack holes form—scientists say they will not, and if they do they will dissolve nearly instantaneously—we may be presented with the opportunity to study them up close, bringing us one step closer to the coveted Theory of Everything. (For those who may not know, black holes are of particular interest because they represent systems where all four fundamental forces, electromagnetic, gravitational, strong, and weak, are relevant. In most molecularly sized systems, gravity is irrelevant.) Then, of course, we stand to learn much from what the LHC was built to discover: the Higgs boson particle—the particle that gives matter mass. In my humble opinion, which admittedly is completely irrelevant, I think it would be a shame to see this multibillion dollar marvel of modern science and engineering packed away into a corner because we feared we may come up on the short end of a very small probability.
Before I close, I would like to change direction for a minute. I find it befuddling that our species fears obliteration so greatly that we constantly construct these doomsday scenarios wherein the Earth and all life on it is destroyed in grand and spectacular fashion, while we largely ignore legitimate threats whose consequences are far more subtle and slowly emergent, yet we have sufficient data to declare them legitimate concerns. I am, of course, speaking about disease and global warming. He we are worrying that the cosmic lottery will turn up a black hole one hundred meters beneath the surface of France, while we continue to burn tons of fossil fuels per person per year and allow the antivaccine movement to grow louder and stronger despite re-emerging diseases long declared under control. It baffles the mind, but I think I know what the problem is. Pandemics and climate change do not necessarily threaten to obliterate humankind as a species. Instead, they will more likely kill a large fraction if not most of the population of Earth while leaving a few survivors to bear the burden of their ancestor's mistakes. People are far more impressed by loud, sudden, inescapable catastrophes, and that mindset may ultimately prove our modern societies' undoing. By comparison, the threat of the LHC is completely impotent.
A useful feature of eWeek is the list of “Most Read” stories, which is currently:
- Microsoft's Big Windows 7 Week. Microsoft's 2006-2007 release of Windows Vista was reported as disappointing; causing many PC users to stick with Windows XP, so the release of Windows 7 has been widely anticipated.
- NASA Space Funding Reaches Critical Point. NASA is planning the future of space travel against a background of controversial decisions, such as: whether to use the Moon as a stepping stone to Mars, whether to use humans or robots to explore space, and whether space travel should be a commercial or government funded venture.
- Why the Droid Can Challenge the iPhone. Should mobile phones be locked to applications and services that Apple Inc. permits, or should you have a free choice to customise mobile applications and services, as with (An)Droid?
- Windows 7 Comes on USB Drives for
Netbooks. Software and documents have traditionally been stored on spinning magnetic discs that are prone to mechanical failure, but we are now in the decade where solid-state memory (with no moving parts), has become a cost effective and more reliable alternative.
- Tilera Talks 100-Core Processor. Some calculations, such as simulating the collision between two black holes, would be too dangerous to try as experiments (1) and too complex to solve on an office PC, so scientists use dozens of computers on a single silicon chip, to complete their calculations in days rather than years. This new technology makes supercomputers available for business applications.
The business-like format of weekly publications made sense when they were printed on paper, but the Internet has enabled the era of reader generated content. The popular http://slashdot.org/, by contrast, has become the classic site where technology news is posted and rated by its readers. It is worth wading through the sometimes inane comments to find an occasional gem of alternative opinion.

Just a reminder - this is the International Year of Astronomy, celebrating the 400th anniversary of Galileo's work. And this Saturday is Astronomy Day. If you happen to be in Houston, go to George Observatory, Brazos Bend State Park between 3:30 PM and 10:30 PM for lots of fun. Otherwise, look to your local university or science museum. And, in the words of one of my favorite people, keep looking up!

Scientists using European Southern Observatory telescopes didn't find any planets quite the size of Earth or any that seemed habitable or even unusual. But their announcement increased the number of planets discovered outside the solar system to more than 400.
Wow, that is amazing. 400 found to date. Most of those are either smaller, or larger, than the Earth, but this increases the chance of finding earth-like planets. We can't reach them yet, of course, but I believe it's only a matter of time before Humanity finds a way to reach out into the stars at faster than the speed of light.
Evidently, Astronomer Stephane Udry from the University of Geneva also believes, also, that there are more planets to discover, maybe even earth-like. Here is a second excerpt from the article:
"I'm pretty confident that there are Earth-like planets everywhere," Udry said in a Web-based news conference from a conference in Portugal. "Nature doesn't like a vacuum. If there is space to put a planet there, there will be a planet there."
Six of the thirty-two new planets found appear to be several times bigger than the Earth. Two others were Jupiter-size or above. Here is a third excerpt from the article:
What astronomers said is especially exciting is the high percentage — about half — of a type of star systems with relatively light stars that had planets around them. This is more than planet-formation theory expected, astronomers said. Two of the four planets found around these type stars were relatively close to Earth size, said astronomer Xavier Bonfils of Grenoble Observatory in France.
The discoveries were made by the High Accuracy Radial Velocity Planet Searcher, which looks for slight wobbles in a star's movements, which would be made by the tug of a planet's gravity on the star. There are no photos of these planets.
Very interesting article. If they find more planets roughly the size of Earth, and if they are indeed 'Earth-like', then that begs the question: Is there life there much like our own? Are they as advanced as us? Or, are they far more advanced?
So many question. It's going to be interesting learning the answers to questions like that. Too bad I'm not immortal, it'd be fun to see what is discovered in the future.
Until next time...

I find it amazing that this young lady is doing this. A bit crazy, maybe - as she is so young and will be alone much of the time - but still amazing. I just hope she succeeds, and comes through it a better, and stronger person that when she began her journey.
It's comforting to know to her family and everyone, I'm sure, that with modern technology, she will be in almost constant contact via e-mail, radio, and her blog.
Young Jessica Watson - as you can see by the picture to the right - didn't talk to reports before she left. Instead she said her goodbyes to Mom and Dad and boarded her sailboat. She left Sydney Harbor Sunday morning Australian Eastern Time.
Julie, Jessica Watson's mother, updated the teenagers blog for her, as Jessica was a bit busy that first day at sea. Here is an excerpt of the blog:
"I know you are all anxious to hear from Jess, but she's a little preoccupied on her first day, so she asked me to post a quick note to let everyone know that the departure went well this morning," Julie Watson wrote on the blog. "I would like to sincerely thank all those wonderful people who came out on the harbor this morning and down to the marina to wish Jess well," she posted only hours after giving her daughter a tearful hug and saying goodbye.
Wasn't much of a first blog-post, but we can't really blame her - can we? Sailing out to sea into essentially the unknkown - even though the world is pretty well charted now, for her it will be full of adventure - with only herself and a few electronics to communicate with the outside world. Must be both terrifying and exciting for her. I know it would be for me.
According to the article, she had several set-backs, at first. She bumped into a cargo ship on her way to Sydney Harbor - causing a call for her not to go, and for her to conduct repairs on her yacht - and then strong wind prevented her from departing on schedule. So, she's had a bit of a rough start, but who hasn't when they have tried to sail, or fly, around the world? To stop just because of a few set-backs would have left her wondering for years to come if she could've done it. That's not to say that we shouldn't worry for her safety, any time you head out on the sea, one must always worry. The sea is a harsh master, and can turn from being the most beautiful and calm, to the most ugly, dangerous, and deadly force on the planet, but that doesn't mean we should stop. And I'm glad that she didn't. It's better to know now, what she is made of, than to live forever with the question mark hanging over her head.
The first leg of her journey will take her from Sydney, Australia past northern New Zealand, to Figi and Samoa. The trip is expected to last about eight months, and the young sailor intends to also sail around the southern tips of South America and Africa, something that is today avoided by most. The southern tips - for those who don't know - are where the oceans meet, Pacific and Atlantic. Each seeming to play a tug of war. Creating massive waves that have been known to capsize, batter, or sink ships many times larger than Jessica Watson's yacht - which you can see to the left.
Have a great journey Jessica Watson. I, for one, will be keeping a watch on your blog, pulling for your success the entire eight months. God speed, good sailing, and may the wind forever be at your back.
Until next time...

The Baucus Bill seems to me more an attempt to end the choice of Americans when it comes to choosing insurance/health care. This should be left to the people to decide, but it isn't - no matter what President Obama and his fellows in Congress tell us. It seems to me that the point of this bill is to eventually force everyone in America - who isn't a ruddy millionaire - to move to a system where the government chooses for us. Not a good idea at all.
So what can we do to stop it? Or, to at least come up with something other than the Baucus Bill?
With the bill now out of Committee, it will be before the entire United States Senate for consideration and debate. So the obvious answer is to phone, e-mail, and snail-mail our objections to the Baucus bill and let our Senators know that we would prefer something else. I have already contacted my Senator's and Representative in Congress. Unfortunately, one of my Senators - Olympia Snow - voted to move this out of Committee. Depending on how she votes, when the full Senate finally votes on the Baucus Bill, will decide for me on whether to vote for her the next time she's up for re-election. If she votes to pass this bill as is, then she won't be getting my vote.
Don't get me wrong, I like the fact that my Senator's are willing to look for answers from either side of an issue, but this bill will harm Americans far more than it will help them. I think part of the reason why so many people are for government Health Care on the Federal level is because our society appears to be moving from an "I'll do it myself, thanks" society to a "let the government do it all for me" society. That is extremely dangerous.
I can uderstand if someone is elderly, disabled, extremely ill, or are veterans and getting help from the government. That doesn't bother me, especially if they truly need it, and for veterans, it should be done anyway as they stand between us and those that would do us harm selflessly. It's the least we owe them. All of those, don't bother me.
It's the young lazy "gen-Y-X-Z-whatever" that think it's the government that should do everything for them. Those people may well be the death of this country as a Constitutional Republic(democrcy) if we aren't careful.
Yes, let's help revamp our Health Care system. It could use some improvement, but let's not turn it all over to the Federal government to handle, all right? That is reminicent of a form of government I never want to see here in America. Ever.
So, call your Senators and Representatives and tell them we don't want the Baucus Plan as it currently stands.
Until next time...
