Caenorhabditis elegans as a Model to Understand the Role of Epigenetic Heritage in Microevolution

In recent decades, epigenetics has been shown to be a promising field of research, since it describes changes in inheritance patterns that do not involve DNA modifications and are related to interactions between the organism and the environment. Epigenetic marks are chemical changes that occur in chromosomes and result in the silencing or activation of specific genes in different tissues. It has been…

Is There Biological Evidence of Life's Recent Creation?

During one of my frequent visits to the office of my high school headmaster, his individual tutelage yielded a life lesson that I’ve never forgotten. His exact words were, “You think you’re right!” Of course I thought I was right, wouldn’t anyone who thought they were wrong change their mind and then immediately think they are right? Now that I’m an adult biologist, I still think that I’m right. Inevitably…

DNA and Design

Imagine walking down the beach and coming across the words “Romeo loves Juliet” written in the sand. Most of us have experienced something like this and would not be surprised, but most people would be surprised to find the entire text of William Shakespeare’s play Romeo and Juliet written in sand. Why is this? The obvious reason is that sand is the wrong material for large writing projects. Sand grains…

Preservation of Dinosaur Soft Tissue: An Update

“You are dust, and to dust you shall return.” This verse from Genesis 3 captures very well the fate of beautifully designed organisms after the entrance of sin into the world. But how long does it take for the organic molecules we are made of to break down after death? In general, the longer the time from death, the larger the amount of decay that should be observed. This is particularly true for soft…

Stability of Organic Molecules: Lessons from Vitamin C

The stability of organic (carbon-based) molecules is an interesting and challenging topic as there are many different types of functional groups, molecular configurations, and molecular collisions to consider. Research on the stability of ascorbic acid (Vitamin C) and other vitamins demonstrates which factors to consider when it comes to the preservation of carbon-based molecules. Ascorbic acid…

Change in Species – Biblical or Not?

Many kinds of animals appear designed for predation and violence, in contrast to what one would expect based on the biblical description of Edenic peace. It seems that animal species must have changed in major ways since the creation, but is this idea compatible with biblical teachings? Many people have asked this question, wondering whether changes in species point to evolution rather than creation.…

The Bible and Microbiology

If microorganisms are indeed ubiquitous and indispensable, it is reasonable to expect to find evidences of their activities in the biblical record. Such an approach may enrich our grasp of the sacred text. This paper intends to show that there is more microbiology in the Bible than meets the eye!

Intelligent Design: The Biochemical Challenge to Darwinian Evolution?

While Christians may be convinced that design in nature points to a Creator-God, the general scientific community has not been persuaded. Perhaps more scientifically respectable work on intelligent design of the kind done by Behe and Dembski will encourage evolutionary scientists to look beyond purely naturalistic mechanisms to explain the complexity and meaning of life.
