Most people recognize that it is more fun to read a story than to plow through a text-book! Usually however the objectives of the two genres are different: the story is for enjoyment and the text for learning. There have been many stories written, however, to communicate an important message. Charles Dickens’ novels like Great Expectations, for example, spring to mind. So it is with Michael and Beverly Oard’s book Uncovering the Mysterious Woolly Mammoth: Life at the End of the Great Ice Age.
No sea animal elicits such fear and terror in the common people as do sharks. Gruesome shark attacks on humans are part of both the folklore and history of many cultures, including our own. Their predatory skill both fascinates and frightens us. Even though sharks rarely attack humans, when an attack occurs, it tends to be widely publicized by the mass media. Ironically, their very survival is now threatened by human-related activities, such as net fishing.
Eggs are complex structures designed to allow the embryo to develop outside of the mother’s body. An animal egg (Latin, ovum) provides a protective shell in which an embryo can develop. In most birds, reptiles, insects, mollusks, fish, and monotremes (mammals that lay eggs instead of giving birth to live young), the egg contains an ovum or, if fertilized, a zygote. A zygote results from fertilization of an ovum, and develops into an embryo. Read the rest of this entry »
If bats were prettier to look at, we might appreciate their amazing talents more. The fact is that bats exhibit some astonishing design features which our engineers and technologists really envy. Traditionally scientists have grouped bats according to their food preferences. There are the fruit bats with good eyesight, the insect consuming, echolocating bats and the vampire or blood consuming bats. Further research has revealed how amazingly these animals are designed for their life styles. Such studies have also revealed that the old fashioned ways of categorizing the creatures according to lifestyle and physical appearance do not really work. This has had some serious implications for ideas concerning whether Darwinian evolution could ever work or not. Read the rest of this entry »
Have you ever noticed that everybody seems to place a high value on problem solving? I can well imagine one’s mother saying “This room is way too messy! How are you going to manage your clothes, toys, electronic gadgets (or whatever) so that this does not happen again?” She clearly expects you to come up with a plan and to follow it! Possibly you may come up with some way to organize your treasures in order to keep mum happy. Read the rest of this entry »
The Creation Science Association of Alberta is delighted to announce that biologist and long time creation apologist Dr. Jerry Bergman has agreed to speak at our Creation Weekend October 14 and 15, 2011. Dr. Bergman is a well known author and speaker on creation issues. His articles in Dialogue are extremely popular and among his published books, our association sells Slaughter of the Dissidents and Persuaded by the Evidence. What makes Dr. Bergman particularly interesting is the story of his rejection of atheism based on deficiencies in evolution theory. Read the rest of this entry »
Pelicans are large water birds with a giant throat pouch designed for storing fish catches. This feature makes pelicans unique compared to all other birds (Burton, M and R. 1977. Inside the World Animal World. Quadrangle). The pelican’s famous foot-long bill, the longest of any living bird, can hold a hundred or more fish (Scott, J. 1975. That Wonderful Pelican. Putnam). The volume of its full bill is up to 11.4 liters, (3 gallons), a size larger than that of most entire birds (Fitzgerald, D. B. 2010. A Critical Evaluation of Origin of Species. TEACH Services, Inc. p. 35). It has a specially designed bone and muscle system it uses to operate its beak and pouch. The pouch normally folds conveniently under its bill, but expands when fishing. These versatile fishermen can scoop up fish with their bills and can store them in their pouch, which can stretch many times their original size. Read the rest of this entry »
Tarsiers are chipmunk sized nocturnal primates known for their enormous night adapted eyes and koala-like body appearance. Their face, which resembles that of an owl, is the epitome of innocence. Tarsiers are covered with very soft, beautiful, velvety fur, which is generally buff, beige, or ochre in color. The head and body together range from 10 to 15 cm in length, followed by a 20 to 25 cm long slender tail. Read the rest of this entry »
An avid fan of spy stories, I have read many which involve an apparently harmless document (like a friendly letter). But the document actually conveys dangerous information if one is provided with the appropriate convention for decoding it. Read the rest of this entry »
One of the most popular mammals is the lovable and cuddly koala. Its appearance has given rise to calling them bears, often teddy bears and, although they are not bears but rather marsupials, the name has stuck. Their fluffy ears, large spoon-shaped nose, round body and bright button eyes make them appealing to everyone. Read the rest of this entry »
A seahorse (family Syngnathidae, genus Hippocampus meaning “horse sea monster”) is like no other animal on earth. It is the only fish that swims upright. It is not just a fish that travels on its tightly curled tail, but its whole body is designed around how it swims. For example, its elaborate balancing mechanism uses an air bubble inside of a specially designed swim bladder to maintain upright posture. Read the rest of this entry »
Nature is so full of wonderful creatures that it must be hard to focus on one for special study. However in recent years, a strange assortment of animals have enjoyed a brief moment of scientific attention. In each case the occasion for this special fame was the publication of the genome of that organism. The genome consists of details concerning the DNA molecules in each cell of the organism. DNA, or the genetic information, is made up of four special molecules (called nucleotides) strung together. It is the order of the nucleotides, like beads on a string, which determines the information content of the DNA for each particular organism. Read the rest of this entry »
The giant panda, one of the most popular and lovable zoo animals, is in the top ten of animal favourites. Called a super large teddy-bear, the panda has appeared as toys and dolls, on calendars, and thousands of other items. Reasons why it is so popular include its cute baby bear face, its cuddly soft roundness, and its clumsy playfulness. It was called a white bear for years because it has black fur on its legs, ears and around its eyes on an otherwise white body. Read the rest of this entry »
Every September, hundreds of thousands of Ontario butterflies converge on Point Pelee, a long peninsula which projects south into one of the Great Lakes. Then away they flutter, across the water and far beyond. Thus begins the amazing mass migration of an insect which unerringly navigates 4000 kilometers to a site where these individuals have never been. The Monarch butterfly, it turns out, is an astounding phenomenon. Read the rest of this entry »
