Chromosomes regulate their own structure through their sequences of non-protein-coding DNA.

Cichlid fish in Nicaraguan lakes show evidence of rapid change.

An average of 70 mutations occur in each person.

The denial of miracles is a recent phenomenon based on how modernity has chosen to understand the workings of nature and what is possible in it. Belief in a personal God (theism), however, argues that through God’s actions, an event that is naturally impossible can be transformed into a real historical event.

Ancient Near Eastern views should be considered part of the history of the idea of evolution. The biblical Creation account, in describing the divine actions through which God actually brought the cosmos into existence, was likely deconstructing the alternative theories or speculations of origins available in the Ancient Near East. Consequently, the biblical narrative can be used as well to deconstruct contemporary cosmogonies and evolution. This article was originally published on Perspective Digest, v.24/3.

Why are we trying to find extraterrestrial intelligence, using our intelligence, while at the same time precluding the possibility that an intelligence was involved in the origin of our world?

How can some people be so certain about evolution, while others, with the same certainty, deny it? Part of the answer can, in broad terms, be boiled down to the difference between what is seen and what is not seen. More specifically, and in the context of evolution itself, this disparity arises from the difference between microevolution and macroevolution. What are these two concepts, and how does the difference between them help explain much of the controversy surrounding the theory of evolution? This article was published on the August 2019 issue of Signs of the Times.

The specific genes have been identified that cause a lizard to match the black rocks it lives on.

Humans have unique “developmental control genes” that distinguish them from chimpanzees and other animals

Is the genetic basis of loss of flight due to mutations in protein-coding genes or in regulatory genes?

Comparison of genomes of jellyfish and sea anemones highlights the importance of orphan genes in taxonomically close organisms.

Confirmation that fathers may sometimes pass mitochondrial DNA to their children violates the assumptions used to calculate the age of the most recent female common ancestor of all living humans. Published in Origins v. 21, n. 2.

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…

A living being is more than the collection of the multitude of organic components of which it is made.

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…

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…

With the scientific knowledge we currently have of nature, is it still reasonable to believe in miracles?

“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…

In a world drowning in information, there is an even stronger search for ultimate truth. It seems the information age expects each of us to sort out misleading advertisements, internet “facts”, and professionally perpetrated misinformation in our own attempts to determine what is true.

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…
