I really hate to admit it, but in certain situations I am old fashioned! In the good old days, biology students were taught about living organisms. We learned the appearance, life cycles and ecological preferences of various groups of plants, animals, fungi and microbes. Read the rest of this entry »

Imagine that you had never seen a car or any automobile before. You might well be curious as to how the device is able to move. So you examine some vehicles in motion and you come to the obvious conclusion that the wheels are the agents of motion. This is all very obvious and all very true. However if you build a device with chassis and wheels only, you will not get very far. What a car requires is an engine manufactured in a factory and fuel to run the engine. Of course your car needs mechanics to maintain the engine too. It is immediately evident to you that the whole system is the result of designers who conceived of the whole idea and who specify how your car is to be manufactured and operated.

It is easy to remind ourselves not to believe everything which is confidently declared as fact, but it is quite another to actually follow that good advice. How many generations of English students, for example, have memorized Shakespeare’s ominous declaration in Merchant of Venice: “All that glitters is not gold–/ Often have you heard that told.” (Act II Scene 7). Even today however, centuries after Shakespeare’s time, we all too often believe appearances, whether they be objects for sale or statements of scientific fact. Read the rest of this entry »

Have you ever tried to imagine what a world without grasses would look like? The scenery might well be pretty bleak. Scientists have long declared that there were no grasses present in dinosaur communities. The plant-eating dinosaurs had to make do, we have been assured, with cycads, ferns, horsetails and trees of flowering plants such as palms and magnolias. Read the rest of this entry »

Hibernation on Demand? Here is a question that has baffled me for quite some time. How could eight people on the ark look after so many animals? Consider this: Noah and his three sons had to look after all these animals for 53 weeks while living in the ark. Read the rest of this entry »

Since the advent of global positioning satellites, or at least since their availability to civilians, scientists have found many uses for these devices. One of the more interesting applications is to track animals, as in the “fish with chips” program. This is a multimillion dollar Census of Marine Life project. In conjunction with this program, thousands of marine animals in the Pacific Ocean, including many fish, have been fitted with electronic surveillance tags. Read the rest of this entry »

As far as our solar system is concerned, astronomers have grown accustomed to expecting the unexpected. Certainly nobody expected liquid water spewing from a small moon of Saturn. Read the rest of this entry »

Imagine a society where there are no managers, just workers. Imagine further that all these workers know exactly what to do and they do it, as vigorously as possible. Imagine too that these workers are farmers which do not make mistakes. Read the rest of this entry »

Intelligent design, and indirectly the creation model, have been in the news a lot lately. Not surprisingly, most of the articles have been sympathetic, not to intelligent design, but to Darwinian evolution, the mechanistic explanation for life so favoured by the majority of scientists.

When we study nature, it is probably a good idea to expect the unexpected.

Certainly the richness and variety of living creatures can never fail to amaze us. One fascinating situation involves certain parasites or disease causing organisms. In several cases, a parasite passes through two entirely different kinds of host in order to continue its nasty parasitic existence. Not only are these situations fascinating, but biologists are mystified how these relationships could ever have developed. Read the rest of this entry »

When we walk outside, putter about the garden, or even splash in waves at the beach, we are making observations of nature whether we realize it or not.

In our backyard during the summer, for example, plump saucy robins take up residence and the male fights off all invader robins. The resident pair is displaying territoriality or the determination to defend their property against all other robins. Other bird species come and go, but our resident robins don’t care.

Scientists are continually discovering remarkable molecular machines which work inside each living cell. One such machine involves proofreading. Anytime you or I copy a document, it is always a good idea to proofread the script. Since each cell copies or duplicates its own genetic code or DNA before cell division, the cell would be well advised to check the new strands to make sure there are no copying errors.

There is nothing like problem solving to keep one mentally alert. Some people might say that the study of nature is a form of problem solving and so it is. Collecting information is only half the battle. The real challenge is to try to explain the data. Read the rest of this entry »

Have you ever discovered that something you thought quite ordinary (or even ugly), was actually a priceless antique? I remember harbouring such sentiments when I was a teenager. Since then, of course, I have learned better how to identify valuable items. Read the rest of this entry »

Not everyone appreciates desert landscapes, however most people will admit, when pressed, that there is an awesome grandeur to some dry lands. The scablands in the northeast section of the State of Washington, are a case in point. Does one like drama? Does one appreciate deserts? The State of Washington has it all.
