1. The Times: “Evidence of Life on Mars Lurks Beneath Surface of Meteorite, Nasa Experts Claim

Is there life on Mars? Some of this week’s biggest “news” is also this week’s oldest news.

A quarter of a century ago, a team of scientists discovered a meteorite in the Allan Hills of Antarctica that was given the name ALH 84001. Its origin was identified as Mars, the story being that an asteroid had hit Mars, breaking off the fragment and hurtling it into space some 16 million years ago. Eventually the fragment was captured by Earth’s gravity and landed in Antarctica 13,000 years ago, the story goes.

A little more than a decade after it was discovered, investigators discovered microscopic structures resembling life on the rock. Due to the meteorite’s alleged Martian origin, the team claimed it was evidence of not simply life on Mars, but that life on Earth began with just such an interplanetary journey. The claim was met with skepticism from all sides, however; scientists pointed out that the microscopic structures were not necessarily biological.

But the discovering scientists didn’t give up. David Mackay of NASA’s Johnson Space Center was part of the team that first examined ALH 84001. He still claims the meteorite is “very strong evidence of life on Mars,” and that claim is now buttressed by a new analysis of the rock conducted via electron microscope.

The new research took a closer look (literally) at magnetite crystals on the surface layers of ALH 84001, which “have the form of simple bacteria,” the Times reports. Could the crystals be the remains of carbon-based bacteria? The research indicates that “about 25 per cent of the crystal structures were chemically consistent with being formed from bacteria.” Apparently that evidence was strong enough to warrant this statement from Times journalist Hannah Devlin: “[The research] showed that microscopic worm-like structures found in a Martian meteorite that hit the Earth 13,000 years ago are almost certainly fossilised bacteria” (our emphasis). Really?

Although nothing scriptural absolutely rules out the idea that God could have created microbial forms on Mars, we are quite skeptical of the “alien” interpretation of ALH 84001. Our skepticism is both because the Bible clearly implies a lack of alien life (or, at the very least, intelligent alien life) and because the research into ALH 84001 appear to be biased by evolutionary hopes. Consider these points:

  • The “life from Mars” hypothesis is built upon a chain of speculation. First is the speculation that ALH 84001 is indeed from Mars. Second is the speculation that the structures are indeed the remains of bacteria. Third is the speculation that if the structures are evidence of life, that life originated on Mars, not Earth. While each is justified in some way, the justifications are likewise speculative and unprovable.
  • Obviously, the fact that we have yet to find life on Mars itself casts more doubt on ALH 84001 as evidence. Does it not seem suspicious that, despite billions of dollars spent searching, our only evidence of life on Mars would actually be from Earth?
  • Even if it were proven beyond doubt that ALH 84001 truly proves life existed on Mars, such proof would not account for an evolutionary origin of life; the question of how complex life formed anywhere in the universe by natural processes remains a riddle for evolutionists.
  • The Times story implies that 75 percent of the microbial structures were not chemically consistent with being formed from bacteria, which shows that such structures can form in the absence of life. Given the odds (compared to only 25 percent that could have formed from bacteria), why the media hype?
  • The Times reports that scientists also possess two similar meteorites (i.e., said to be from Mars, and said to show the same signs of microbial life), one from Egypt and the other also from Antarctica. If it’s a stretch to imagine one meteorite carrying life from Mars to Earth, how much less likely is it that such is a regular occurrence? Of course, astrobiologists may beg the question by claiming the multiple meteorites show it’s a “common process.” But we would say the meteorites show, for example, contamination of meteorites by microbes living in Earth’s atmosphere.
  • Another report this week on a Martian lake concludes with a section titled “Life’s Chances on Mars.” It reminds us that for years, evolutionary scientists have tried almost everything to find evidence of life on Mars, with little success. That, in turn, suggests a systematic bias that makes us even more skeptical of every new “life on Mars” hype.

2. PhysOrg: “‘Super-River’ Formed the English Channel

It’s not only creationists who point to the role of catastrophic events in shaping earth’s geologic history. A new study sheds light on how Britain was separated from the rest of Europe by a “super-river.”

Scientists publishing in Quaternary Science Reviews examined sediments from the bed of the Bay of Biscay (to the west of France) in a bid to better understand the formation of the English Channel (which separates Britain from France and the rest of Europe). According to the team, a “super-river” known as the Fleuve Manche (or Channel River) carved the channel after a glacial lake overflowed.

The researchers’ story begins some 500,000 years ago, when (according to them) Britain was connected to France via a land bridge near Dover (which today is Britain’s nearest point to France). During an ice age 450,000 years ago, water stuck between ice sheets formed a large glacial lake “behind” the land bridge.

The researchers dated the sediments they gathered from the Bay of Biscay and claim they were deposited by the super-river in three separate incarnations: one 450,000 years ago, another 160,000 years ago, and a third less than 100,000 years ago. During ice ages the sea level fell, opening the land bridge so that Britain was connected to Europe. Each time, the lake eventually overflowed and the super-river split Britain from the continent. Not only that, but the consequential “megafloods,” as the Daily Mail puts it, carved through chalk beds, resulting in Dover’s famous white cliffs.

Although the research is interesting, the idea that the English Channel was carved by a megaflood isn’t new. We last reported on it in July 2007, when we wrote:

Let’s take stock here: an enormous amount of water, a short timeframe, evidence of water-gouged landforms, and a large basin left behind. Does this sound strangely familiar? . . . According to a biblical interpretation, it is likely that the Channel was formed at some point after the waters receded from the one true “mega-Flood” that the world has experienced.

3. Wired: “There’s No Such Thing as a ‘Simple’ Organism

It could be “the most thorough study ever of a single organism,” and what is the unsurprising conclusion? “[E]ven the simplest creatures are more complex than scientists suspected,” reports Wired’s Brandon Keim.

German and Spanish scientists have conducted a study of the organism Mycoplasma pneumoniae, a microbe considered extremely “simple” compared to most life-forms. With only a fifth as many genes as E. coli, M. pneumoniae is a good starting point for biologists to learn more about how cells work. The surprise, however, is that its genetic workings are “much more subtle and intricate than were previously considered possible in bacteria,” write two University of Arizona biologists in a Science commentary on the research.

The team studying M. pneumoniae spent time documenting the proteins used by the microbes, recording gene activity, mapping the microbe’s physical structure, and taking note of the chemical reactions inside the organism. “What emerged was a picture of surprising complexity,” Keim writes. The findings challenge scientists’ ideas about how genes work, showing that, as Keim explains,

Groups of genes thought to work in unison did so only intermittently. At other times they worked in isolation, or in unexpected configurations.

Just as importantly, the study showed that the 3-D arrangement of the genome is crucial to cellular function. More information is stored in genes than in its base pairs. “Linear mapping of genes to function rarely considers how a cell actually accomplishes the processes,” write the University of Arizona scientists, who add, “There is no such thing as a ‘simple’ bacterium.”

Anne-Claude Gavin of the European Molecular Biology Laboratory, who co-led the project, explained, “What we’ve learned is that if you want to understand any cell and the protein complexes it makes, you can’t infer what happens from the order the genes are in.”

Her colleague Peer Bork added, “There were a lot of surprises. Although it’s a very tiny genome, it’s much more complicated than we thought.”

That complexity shouldn’t be a surprise, though: as our knowledge of the cell and life’s genetic basis increase, we continue to encounter workings that transcend our understanding. But virtually none of this complexity was visible to Darwin. Would he hold on to faith in the idea of evolution if he was aware of the challenges posed to it by even the simplest of cells?

4. ScienceDaily: “Study Pits Man Versus Machine in Piecing Together 425-Million-Year-Old Jigsaw

Reassembling half-billion-year-old fossils from bone fragments: a task so complicated that only computers can handle it?

Researchers from the University of Leicester and Canada’s Royal Ontario Museum report in the journal Palaeontology an interesting “competition” they held: do humans or computers do a better job reassembling fragmented old fossils?

The scientists looked at how well paleontological “experts” were able to rebuild conodont fossils compared to the results of computer-based statistical methods. Conodonts were eel-like creatures thought by evolutionists to have lived hundreds of millions of years ago. Their many teeth, often scattered throughout marine rocks, complicate the process of reconstructing their skeletons. Another difficulty is that scientists have no living examples of conodonts on which to based their reconstructions. These factors make reassembling conodont fossils the equivalent of putting together jigsaw puzzles without any picture as a guide. University of Leicester researcher Mark Purnell, one of the study leaders, explained the difficulty:

“When a vertebrate animal dies, whether it’s a fish, a sabre-tooth cat or a dinosaur, the flesh rots away and the bones of the skeleton are usually scattered before being fossilised. In order to interpret them correctly, the palaeontologist must piece them back together, or at least work out which bits are which.

“To make matters worse, within any one [conodont], teeth from different parts of the skeleton looked almost identical! Now we have a jigsaw puzzle with no picture, where each piece could go in different places. But just so it’s not too easy, conodont teeth are also microscopic.”

What was the result of the friendly “competition”? The most reliable reconstructions were produced not by computers, but instead by expert paleontologists. However, computers were more consistent than human researchers; less experienced paleontologists were prone to mistakes, and even the expert paleontologists had their own disagreements.

Our point is not to emphasize the value of either human- or computer-led research; obviously each has its place. Instead, this story reminded us of the difficulty in piecing together any poorly preserved or scattered fossil, especially when (as the scientists indicate) we have no living representatives to serve as a “guide.” When the fossils are incomplete, how can anyone—human or computer—know a reconstruction is accurate? Further troubling is the role evolutionary dogma plays in telling paleontologists how a fossil “should” look if it is assumed to be a transitional form.

For these reasons, this research reminds us of the caution we should accord to every fossil reconstruction. Especially when it comes to supposed “ape-men” like Lucy, Ardi, and others, we must be aware of the fact that evolutionary ideas may be (consciously or subconsciously) guiding the reconstruction, giving scientists a false sense of certainty. Even statistical techniques, when it comes to organisms that have no living representatives, may include tacit evolutionary ideas.

5. PhysOrg: “Bacterial Gut Symbionts Are Tightly Linked with the Evolution of Herbivory in Ants

Most ants are carnivorous, yet some are herbivorous. But how do the herbivorous species get the nutrients they need?

For creationists, envisioning a world without death—as was the case before Genesis 3—entails envisioning a world without carnivory. And while some creationists have argued that insects are not alive in the biblical sense (and, thus, ants’ victims do not “die”), a new study shows how ants can survive without eating other organisms.

The research, from Chicago’s Field Museum, considered how ants that eat plant matter only can acquire the nutrients they need to survive, especially proteins—which isn’t a problem for ants that eat other organisms. The answer may lie in symbiotic microbes that live in herbivorous ants’ guts. The researchers learned that Rhizobiales, an order of bacteria, lives inside most herbivorous ant species but not carnivorous species. Rhizobiales microbes are already known to help plants convert nitrogen from the atmosphere into biologically usable compounds.

“It, thus, seems likely that the acquisition of nutritional gut bacteria has enabled the evolution and maintenance of herbivorous, nitrogen-poor diets across the ants,” a press release on the research states. The researchers also found other microbes living in some herbivorous ants’ guts.

While evolutionists see the microbes as having enabled previously carnivorous ants to survive herbivorously, creationists can just as easily see the opposite: God may have created all ants to be herbivorous, with specially designed gut microbes helping supplying essential nutrients to ants. In the post-Fall world, some ants have survived without the necessary microbes by resorting to carnivory—but what we see today are only flawed versions of the Creator’s original designs.

6. And Don’t Miss . . .

  • For years, News to Note has reported on stem cell research that does not use embryonic stem cells—which require the destruction of a viable human embryo. But despite the promise of this research, U.S. regulators have approved thirteen new lines of embryonic stem cells in response to President Barack Obama’s easing of restrictions on federal funding for new embryonic stem cell lines. According to the BBC, nearly one hundred more lines could be approved next year as well.
  • BBC News offers another report lauding the intelligence of ravens (crows), who have been observed to hunt as a pack. Ornithologists in Israel have watched two ravens block the escape route of a lizard while others attacked it, then all sharing in the spoils. This shows that “they must have some understanding of what each other is thinking, and be able to realise that by cooperating, they will share in the reward . . . they must also have an understanding of how [the lizard] will likely react.”
  • Last week we told you about the formerly “comatose” Rom Houben who, neurologist Steven Laureys discovered, was actually conscious. In fairness, this week we offer a rebuttal to the story by “Bad Science” columnist Benjamin Radford. He writes, “Houben’s injuries have left him unable to move his limbs, and therefore he ‘wrote’ the words with the help of an assistant who guided his fingers to a specially-made keyboard. Was she helping him type, or typing for him?” Although Radford does not dispute Houben’s (very partial) recovery (and, thus, our point about euthanasia remains), he wisely encourages cautious thinking.
  • How’s this for bizarre: according to the Daily Mail, Bulgarian government scientists claim to be in contact with aliens. “Aliens are currently all around us, and are watching us all the time,” said Lachezar Filipov, reportedly the deputy director of the Bulgarian Academy of Sciences’ Space Research Institute. Filipov’s team is said to be studying crop circles, “which they believe answer questions beamed into outer space.”
  • Is a “Wiki”-like system the best way to produce a Bible translation? Apparently the principals of Conservapedia’s Conservative Bible Project think so. We are troubled, however, by the idea of a Bible translation editable by anyone, especially one predicated on such political ideas as that the Bible should “Express Free Market Parables; explaining the numerous economic parables with their full free-market meaning” (one of the ten guidelines of the Conservative Bible Project). Likewise, the idea of “prefer[ring] conciseness over liberal wordiness” (guideline ten) and its accompanying definition suggest the founders of the project want to apply the word “liberal” to anything they perceive as unlikable. Without attacking the founders’ intentions, we believe the Word of God should not be subject to ongoing re-translation on an Internet forum by individuals who may have no training whatsoever in the languages the earliest Bible texts.
  • Answer this: what is the evolutionary incentive for humans to save “special” carnivores? In an evolutionary world, would there be any reason other than self-interest to save another species?
