Genetic Similarity Does Not Necessarily Mean Common Inheritance
Different populations of stickleback fish have parallel genetic adaptations to similar local habitats.
What a Wood Warbler Can Tell us About “Filling the Earth”
Hybridization among wood warblers suggests “filling the earth” through dispersal, speciation and adaptation to local habitats.
Mr. Potato Head and Evolutionary Anomalies
Much effort has been expended in attempts to arrange living organisms in a pattern based on genealogy. However, a tree-like pattern is not as evident as evolutionary theory would predict.
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…
Modern Bird Lung Design Documented in Rapidly Buried Fossil
A fossil bird recovered from Cretaceous lake deposits in China shows preservation of some soft tissues, including a pair of lungs that appear to have functioned in a way similar to those of living birds.
Pterosaurs of the Triassic: An Update
This post complements an article that was written in 2014. Since then, there have been some interesting developments in the area of Triassic pterosaurs that are worth mentioning, the most important being the recent description by Britt et al. (2018) of a Triassic pterosaur from the Nugget Sandstone of Utah.
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…
Archaeopteryx: Bird or Reptile? Or Not?
Archaeopteryx is arguably the most famous fossil ever discovered. It has a mixture of bird-like and reptile-like traits, and was first reported only two years after Charles Darwin published his book, The Origin of Species. Since then, another eleven Archaeopteryx specimens have been recovered from the limestones near Solnhofen, Germany.
Organisms in Their Niche: Passive Modeling Clay or Problem-Solving Entities?
One person’s cultural background can bias their view about people from other cultures… even before they have ever met. Could people also have a bias about how they think about other creatures? It may even be possible that scientific culture could prejudice the way researchers see creature-environmental relations with the potential to bias whole research programs.
Sociobiology and Creation
Picture a ground squirrel who spots a predator and gives an alarm call. The call alerts other squirrels who run for cover, but the call attracts the predator to the one giving the alarm. This unfortunate squirrel may give its life to protect its neighbors. How could this altruistic behavior, assisting other individuals at the expense of the calling squirrel, result from evolution? This seems contrary…
The Perfect Wing Stroke
What is the utility of a fourth or a fifth of a wing stroke? Could any insect or bird get by with a wing that is a fraction of its normal size? Could it serve its purpose working at a reduced capacity? These questions are a challenge for those who accept Darwinian gradualism and adaptation. According to the Darwinian evolution theory, biological traits arise by small genetic variations steadily modifying…
Birds and Flight
Recently I flew to London on the new Boeing 787 Dreamliner. Despite what media hype might lead a Dreamliner passenger to expect, there were no fires on board and the experience wasn’t particularly different from what I’ve experienced on innumerable other flights. From my perspective, the seats were too small, too close together and too hard. That is not to say that there were not some differences,…
Cambrian Explosion and Darwin's Doubt
If one accepts the evidence of the Cambrian Explosion at face value, the Darwinian theory of evolution is falsified. Unsurprisingly, evolutionists have tried to explain the Cambrian Explosion as an artifact, due to the incompleteness of the fossil record. However, there is an explanation for the Cambrian Explosion that is consistent with the data. An intelligent being could generate the genetic information needed for a diversity of body types in a short time.
Is the Theory of Evolution Scientific?
I suggest that the level of confidence any one person has in the truth of evolutionary history directly reflects the degree of confidence they have that science is the surest way of finding truth in any topic, and/or the confidence they have in the assumption of naturalism.
Sociobiology: Why Do Humans Behave the Way They Do?
For a large part of the 20th century, there was much discussion about evolution’s difficulty in explaining altruism. This was an important, unsolved problem.
Humans and Chimpanzees are 99.4% Identical...or Are They?
Recently, the city buses in my neighborhood gained a new set of brightly-colored advertisements along their sides. In bold letters, they proclaimed that humans and chimpanzees are 98% identical: “Come and meet your relatives.”
When Science Rejected God
At present, there is an almost absolute exclusion of God from scientific textbooks and journals. Unfortunately, such a closed attitude prevents science from following the data of nature wherever it may lead. Science cannot evaluate evidence for God as long as He is excluded from consideration.
The Message of the Trees in the Midst of the Garden
If, in Paradise Regained, it appears that the tree of knowledge has outplayed its peculiar role, that it is not there, or that it is somehow fused to its sister tree, forming an arch over the river of life, we should hesitate to conclude that God will ever be in retreat with respect to the ideology of freedom.
