Sweet Potato Whiteflies (public domain image)I write and speak a lot about mutualism (see here, here, here, here, and here, for example). Not only do I find it to be incredibly fascinating, but I also think it is a clear indication that the living things we see around us have been designed. Indeed, the various ways in which two or more organisms work together to survive are often so intricate and precise it seems crystal clear to me that these mutualistic partners were made for each other.
One of the very common types of mutualism you see in creation involves microorganisms inhabiting and helping plants, animals, and people. As I mentioned in a previous post, for example, our bodies are teeming with microorganisms, and without them, we would not be nearly as healthy. Animals and plants also harbor an amazing variety of microorganisms, which help them do such diverse things as digest cellulose (in the case of termites) and resist heat (in the case of panic grass). Well, I recently came across yet another example of mutualism between an animal and a microorganism, and it adds yet another level of complexity to the process.
This is a model of what a eurypterid might have looked like (Click for credit)Scorpions are part of phylum Arthropoda, which contains all animals that do not have backbones but do have an outer coating of “armor,” which scientists call an exoskeleton. This exoskeleton is a complex structure that is formed primarily with proteins and a molecule called chitin (pronounced KY tin). While the scorpions we know today live on land, the fossil record holds remains of some very scorpion-like animals that most likely lived in water. They are called eurypterids, or sea scorpions.
As far as we know, sea scorpions are now extinct, but you can find their fossils in rocks near the bottom of the geological column. Using scientifically irresponsible dating techniques, paleontologists think that the oldest sea scorpion fossils are well over 400 million years old.1 Evolutionists think that those sea scorpions eventually found their way out of the water and invaded land, evolving into modern-day scorpions.
So why am I telling you this? Well, a new report published in Geology tells us about a surprising discovery made by scientists who were studying a sea scorpion fossil they say is 417 million years old and a land scorpion fossil they say is 310 million years old. This discovery casts a lot of doubt on those outlandish ages.
A European robin like the ones used in the study
(Click for credit)In a previous post, I mentioned that some Christians don’t like the idea of quantum mechanics. In fact, some take great pains to fight against it, considering it a threat to a Christian worldview. Whether or not you like a theory, however, has little to do with its validity. Only the data are important, and when it comes to the data, there is overwhelming support for the validity of quantum mechanics. As a result, it’s hard to fight against it. In fact, a recent study suggests that rather than fight against it, we should marvel at how God has used it to accomplish some truly incredible things.
The study focused on how European robins sense the earth’s magnetic field. Lots of animals have been shown to be sensitive to the earth’s magnetic field, and they use it to help them navigate. In some cases, such as that of the rainbow trout, it has been shown that the animal does this with magnetite particles in a certain tissue. Those particles move in response to the earth’s magnetic field, allowing the animal to use them to orient itself.1
Migratory birds and homing pigeons have also been shown to be sensitive to the earth’s magnetic field. Magnetite has even been found in the upper beaks of such birds, which lends support to the idea that they sense the earth’s magnetic field in a way that is similar to that of the rainbow trout.2 Oddly enough, however the magnetic sensitivity of these birds is affected by light. Yellow and red light, for example, disrupt the birds’ ability to sense the earth’s magnetic field.3 This is more than a little odd, since the motion of magnetite in a magnetic field should not be affected by light.
A stone tool, somewhat similar to those discussed in the article (click for credit)I am not sure how this ever made it past the reviewers, but an article in the January 28, 2011 issue of the journal Science discussed research from an intelligent design standpoint. The article reports on research done by Hans-Peter Uerpmann and his colleagues. They were excavating a rock shelter at the end of a long limestone mountain near Al-Madam, Sharjah Emirate (of the UAE), and they found stones that were shaped rather differently than most of the other stones in that same area. Most of them were tapered at one end and curved at the other, and there were specific surfaces that seemed perfectly suited for fingers to hold onto the stones.1 The research is considered important, because if the results stand up to scrutiny, they upset current ideas regarding the migration of human beings out of Africa.
It is hard to keep track of the evolutionary model of the origin of human beings, because it changes abruptly every time new data cannot be forced into compliance. Nevertheless, the evolutionary view currently accepted by the majority of evolutionists is that modern human beings evolved in Africa and then started migrating from there about 50,000-75,000 years ago. Dr. Uerpmann’s research team, however, found these stones in the Arabian peninsula, and based on scientifically irresponsible dating techniques, they claim the stones are 125,000 years old.
In my two previousposts, I reported on a lecture series given at Taylor University by world-renowned philosopher Dr. Alvin C. Plantinga. In this post, I want to discuss his final lecture, which was, by far, the most interesting of the three.
As was the case with his other two lectures, Dr. Plantinga began with a couple of funny stories. He then jumped into the topic at hand, which is how science should deal with divine action in the world. Not surprisingly, there are many who think that any consideration of God taking action in this world is an assault on science. For example, he quoted Dr. H. Allen Orr, a professor of Biology at my alma mater (The University of Rochester), as saying:
It’s not that some sects of one religion invoke miracles, but that many sects of many religions do…I agree of course that no sensible scientist can tolerate such exceptionalism with respect to the laws of nature.
Surprisingly, enough, however, there are many theologians who have the same view. Dr. Plantinga noted that Rudolf Karl Bultmann (a Lutheran theologian), John Macquarrie (an Anglican theologian), and Langdon Brown Gilkey (an American Protestant theologian) all agree that modern science forbids God to do any miraculous works. As Dr. Plantinga noted, these theologians believe that since God put the natural laws in place, even He cannot break them.
Alvin Plantinga, a thoroughly brilliant and thoroughly enjoyable man.Dr. Alvin C. Plantinga is arguably the most important Christian philosopher alive today. Best known for his works in epistemology, metaphysics, and Christian apologetics, he is widely credited for the revitalization of Christian philosophy that took place in the mid-to-late 1900s. Indeed, a 1980 Time Magazine article reported on the remarkable resurgence that had occurred in religious philosophy and gave Plantinga the lion’s share of the credit for it, calling him “America’s leading orthodox Protestant philosopher of God.” Thanks to a member of my church, I found out that he would be lecturing at Taylor University, which is only about 35 minutes from my home. I was incredibly excited to hear such an amazing servant of God, and he certainly didn’t disappoint.
His first talk was entitled, “Science and Religion: Where the Conflict Really Lies.” He started his lecture with several witticisms. For example, many people are surprised to learn that although he is a Protestant, he is currently on the faculty at the University of Notre Dame, a Roman Catholic institution. He says many people wonder why he left his faculty position at Calvin College to go to Notre Dame. “It’s actually quite simple,” he said, “I wanted to become Pope, and there has never been a pope from any university with the name Calvin.” He said he thought it would be fun to be the first Protestant Pope, and the University of Notre Dame would help him get closer to that goal. But he said he quickly found out that “becoming Pope is harder than you might think,” so his dream is still not realized.
I actually think I understand why Dr. Plantinga went from a Calvinist college to a Roman Catholic university. Like all deep thinkers, he understands that in order to be truly educated, we must look at issues from a variety of perspectives. I think part of the reason he ended up as a Protestant philosopher at a Roman Catholic university was so that he could see various aspects of Christian philosophy from a different perspective. I find that quite laudable.
Oil slick from the Deepwater Horizon spill as seen by a NASA satellite (public domain image)In September, I discussed some of the scientific findings regarding the Deepwater Horizon oil spill that spewed hundreds of millions of gallons of water into the Gulf of Mexico. Those findings were quite encouraging. They showed that the ocean’s natural “cleanup crew” was busy trying to mitigate the damage that we did to the gulf. They demonstrated that the populations of bacteria rose and fell depending on what kinds of hydrocarbons were present in the ocean. This demonstrated there was a good chance that bacteria could take care of most of the oil that was released into the Gulf.
There was one nagging problem, however. While many of the hydrocarbons that were released into the Gulf were being destroyed by bacteria, the lightest hydrocarbon (methane) seemed to be persisting stubbornly. A study of the lighter hydrocarbons in the Gulf, which was published in October of last year, showed that very little methane from the spill had been destroyed.1 In fact, one of the authors of the study said that the results indicated:
methane would persist for many, many years, if not almost a decade.2
Well, it turns out that this particular scientist (and those who agreed with him) just didn’t have enough faith in the ocean’s natural cleanup crew!
Last year, I posted my take on Dr. Craig Venter’s amazing accomplishment in which he copied the genome of one bacterium and transplanted it into a different (but very similar) species of bacterium whose DNA had been removed. It was a marvel of biochemistry, but as I pointed out, it clearly demonstrates the impossibility of abiogenesis (the fantasy that life originated by natural processes). One commenter announced that my claim was bogus and undermined my credibility. He further said that the claim was “infantile and wrong on so many levels.”
Well, I guess there are now at least two PhD chemists whose credibilities have been undermined and who are “infantile and wrong on so many levels.” It turns out that Dr. Fazale Rana, a PhD chemist (with emphasis on biochemistry), also takes the same position in his book, Creating Life in the Lab. Indeed, the theme of the entire book is how modern developments in the attempt to make artificial life have conclusively demonstrated that life cannot the the product of strictly natural processes.
While the goal of Rana’s book is to survey all the different ways scientists are trying to produce life in the lab, he starts out his first discussion of actual laboratory results with Venter. This is probably because Venter has come the closest to producing artificial life. However, as I stated in my original post, Venter’s team had to rely on already-living cells no less than three separate times in order to produce their “synthetic” life form. As Dr. Rana states in his discussion of Venter’s results:
Though not their intention, Venter and his colleagues have provided empirical evidence that life’s components and, consequently, life itself must spring from the work of an intelligent Designer. (p. 46)
Bacteroides trichoides, one of the many species of bacteria that live in the human intestine (CDC image)One of the most fascinating aspects of the biological world is the phenomenon of mutualism – two or more different species living together so that each organism benefits. I have blogged about this topic before (here, here, and here), and I discuss it quite a bit in my science texts. Technically, it is a subcategory of symbiosis, where two or more organisms live together. If all organisms benefit from this living arrangement, we call it mutualism. If one benefits and the others are not harmed, we call it commensalism. If one benefits and another is harmed, we call it parasitism.
Many scientists consider mutualism (and symbiosis as a whole) to be a fairly uncommon thing in nature. Sure, you can find some organisms that help each other out from time to time, but overall, nature is about organisms “battling it out” for survival. Nothing could be further from the truth! While organisms do compete against one another in nature, they also help each other quite a bit. As George D. Stanley, Jr wrote a few years ago in the journal Science:1
Symbiosis is the most relevant and enduring biological theme in the history of our planet.
Indeed, symbiosis (and mutualism in particular) is incredibly common throughout creation, and nothing makes that more apparent than a study of the microbiological communities that live in each one of us.
The journal Science recently reported on the results of The National Survey of High School Biology Teachers.1 This survey studied the teaching habits 926 public high school biology instructors that are supposed to be representative of the nation as a whole. The results cause alarm in some and hope in others.
The “take home” result is that 13% of the teachers surveyed spend at least one hour teaching either creationism or intelligent design in a positive light. In contrast, 28% of teachers are strong advocates of evolutionary biology, stressing it as a unifying theme in the life sciences. The majority (roughly 60%), however, advocate neither position. In fact, many of them spend as little time as possible on the subject of origins.
