The specific genes have been identified that cause a lizard to match the black rocks it lives on.
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.
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…
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…
“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…
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…
Can we detect design in nature? What kind of arguments have been used to make the design inference?
Reactions comprising the nitrogen cycle are catalyzed by complex protein machines, some of which may be Irreducibly Complex (IC).
Poor design in Rubisco can now be added to the growing list of failed Darwinian arguments from ignorance.
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!
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.
Trilobites are complex, elaborately segmented forms with jointed appendages and swimmerets, antennae, compound eyes, and cephalized, or head-to-tail, nervous systems.
Zoology and genetics are required courses for biology majors. Both subjects are usually structured around the theme of the theory of evolution. A careful examination of the scientific basis of these disciplines shows that the evolutionary framework doesn't fit with a lot of their fundamental aspects, however. Some of these topics even constitute strong evidence in favor of intelligent design.
The integration of Bible and science is an uphill work that requires careful reading of both the Bible and of scientific data. Because no other natural science has traveled so great a distance down an anti-biblical road, no other science requires this corrective procedure more than biology.
This brief monograph was written to champion the views of a minority in the scientific community. This minority holds that it is possible to accept this ancient report of Earth's creation at face value — and still be a true scientist. But the main purpose is to go a step further. It will be argued that a close examination of life can lead observers to the logical conclusion that life itself is an actual evidence for creation.
As a scientist, I frequently find myself taking a polemic stance in defense of creationism. In doing this, I easily lose sight nature as a revealer of its Creator. It is a pleasant change to contemplate my field of scientific interest, looking for insight about the Creator.
The philosophical context in which biology is presented can make an important difference in its meaning for the student. The philosophical worldview of the biblical Christian is quite different from that of the non-Christian; thus, the biology teacher may have a profound influence on the development of worldview by the student.
If I accept a creationist worldview, what are some implications on my understanding of God and His action…
Intelligent design seen from nitrogen-processing bacteria to bird eggshells and respiratory regulation.
