In his famous 1959 article, Dr. Bernard Kettlewell described his research on the peppered moth as the “consummation and confirmation” (p. 53) of Darwin’s theories. (B. Kettlewell. 1959. Darwin’s Missing Evidence. Scientific American. March pp. 4 8-53) Since then, the peppered moth has become standard fare in biology and genetics texts. Educators really like this example because it is “extremely visual” and thus easily understood and remembered. While all scientists, whether creation model support ers or evolution model supporters, agree that shifts in the proportions of various characteristics do take place in nature, only the evolutionists draw more extensive conclusions from the data. For example, Nelson Canada’s 1993 high school text Biolog y (authored by teachers from Alberta and Newfoundland), suggests that students explain the statement “Evolution and adaptation usually occur by means of small changes” in connection with the case of the peppered moth.

“Strange is this little creature, because the whole organisation of his body is extraordinary and strange and because his external appearance, at the first sight, has the closest similarity to a little bear.  This also led me to give him the name little water bear” (cited in Greven 2015).

It goes without saying that all living creatures are interesting. Some, however, possess an extra mystique. These are organisms which have closely similar counterparts preserved in stone. Obviously a long history has been enjoyed by living examples of such fossil specimens. The living populations are called living fossils. But what about the rest of living creatures, whose preserved remains we do not find in low lying rock? Is their past any different? Let’s delve into the story of the living fossils in order to find out if they are really special and what is their real claim to fame. Read the rest of this entry »

Creation Science Association of Alberta is delighted to announce that biologist and philosopher Dr. Paul Nelson has agreed to be our featured speaker for Creation Weekend, Friday evening and all day Saturday October 18 and 19, 2013. Dr. Nelson is a friendly and non-confrontational individual who makes the latest information in biology come alive in his lectures. He not only describes the issues, but he tells us what the significance of the material is.

One might suppose, judging by this title, that the beaches in Canada’s maritime provinces are not happy places to visit. Actually they are beautiful. Nevertheless, the story of these landscapes provides remarkable food for thought. Read the rest of this entry »

In Nova Scotia, as elsewhere in the Maritimes, we discover that fossils are an exciting part of the landscape. Not the least of our discoveries are the dinosaurs of Parrsboro. Dinosaurs?? We thought western Canada had exclusive claim to such Canadian artifacts. Not quite. West of Truro, along the north shore of the Minas Basin, we find the touristy town of Parrsboro. The scenery is beautiful, with blueberry crops growing on local hummocky hills. Furthermore the beaches along this stretch of coast are famous for fossils, dinosaur fossils to be specific.

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 »

Michael Faraday (1791-1867) was an English scientist (in the terminology of the time he was called a natural philosopher) who made critical contributions to the electromagnetism and electrochemistry fields. Judged as one of the leading experimentalists in science ever, he was one of the most influential scientists in history. Called the father of the electronics revolution, he also did critical work in chemistry (Ludwig, C. 1978. Michael Faraday: Father of Electronics. Herald Press). Read the rest of this entry »

Part of the fun of attending the CRS Conference in St. Louis, Missouri, at the end of July 2025 was participating in the pre-conference geology workshop, which included a morning field trip before the temperature became too hot (highs of 35°C every day of the conference).  As a Canadian, I joked that I could finally thaw out completely.

Four times a year, a group of scientists who recently participated in more than one million dollars worth of research into radiometric techniques for estimating the age of rocks, now conduct meetings to communicate the results of their research to the public. These scientists sought a fundamental correction to the usual assumptions that the earth is extremely old. 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 »

Dr. John Baumgardner addressed large appreciative crowds at CSAA’s Creation Weekend in October 2016. Following his introductory lecture on Friday evening (“How language powerfully affirms God’s reality”) [described in the previous issue of Dialogue], he continued the next morning with “Mendel’s Accountant: Why Darwinism Fails”. This work resulted from a collaboration with geneticist Dr. John Sandford of Cornell University. Many people in modern society find Darwin’s conclusions extremely appealing: the idea that competition in nature ought to lead to organisms better suited to the environment. While this is reasonable, there are limits to how far this idea can take us. Read the rest of this entry »

Truly there are few things as thrilling as beautiful music. Was it not Shakespeare who wrote “If music be the food of love, play on!” Indeed music not only fosters romance, but it can also make us laugh, or cry, or move with the rhythm, or all of the above at once. There are few things which play on our emotions the way music does. Music however is not a gift unique to people. There are other created creatures with wonderful musical talents. Consider the songbirds for example. Read the rest of this entry »

Sometimes it seems as if information is the most important commodity in our technological age. Information, of course, can be put to good or bad uses. We would all agree, no doubt, that computer viruses are a bad use of information. In that situation, a small piece of computer code (information), once it is inside your computer, can take over the whole operating system, with disastrous results for your interests. Of course such problems are nothing new. The term “virus” comes from natural phenomena that do the very same thing to living cells. Invading information occurs to even the smallest cells, bacteria. In fact, some of the bacteria that most threaten our health, are themselves the victims of invasive information from outside unrelated sources. Consider the case of the infamous Escherischia coli 0157:H7, cause of potentially fatal hamburger disease and in some isolated situations, contaminated water. Read the rest of this entry »

The gecko, famous in some circles in car insurance commercials, is a very unique but average sized lizard. It is well known among biologists for its chirping vocalizations and its sophisticated adhesive toe pads that allow it to climb with ease up smooth vertical surfaces. Actually, the gecko’s ability to run vertically up and down at will has astonished almost everyone who has ever seen them, from Aristotle in the 4^th century BC to today. Read the rest of this entry »
