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…
A Review of the Nature Documentary “The Riot and the Dance”
Most nature documentaries include some language that refers to an underlying naturalistic understanding of origins. However, the recently released nature documentary “The Riot and the Dance” breaks this common pattern in a refreshing way.
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.
Microbes, Symbiosis, and the Lesson of Interdependence
A very common reaction to the thought of “microbes” is a compelling desire to slather up in hand sanitizer! However, it is seldom realized that the greatest majority of microorganisms are at the very least not harmful, and at the most necessary for human life! Many aspects of microbial interaction with our environment allow it to be so perfect for humans. Some of these aspects include oxygen generation,…
Teeming Creatures of the Sea!
The number of different kinds of living organisms is one measure of biological diversity, or what has become known as “biodiversity.” Our world’s oceans have the highest known biodiversity, second only to the number of species found in the tropical rainforest.
The True Colors of the Ocean
Have you ever snorkeled or scuba dove in a coral reef? If you have, and I asked you to describe the experience in less than five words, I bet your answer would be an explosion of color. Well, maybe you would express it slightly differently, but I am sure that you would include the word color in your description. Coral reefs are one of the most colorful spectacles of nature; electric blues, vivid yellows,…
Annotations from the Literature
A collection of short commentaries on scientific papers published in 2015, covering topics such as phylogeny of moths, beak variations in species of Galapagos finches and scrub jays, functional synthetic chromosomes, horizontal gene transfer, Jurassic fossil snakes, stasis, trace fossils of swimming tetrapods, and habitat diversity in the fossil record. Published in Origins, v. 64.
Creation, Flood and Biogeography: Part 3
The third part of this series on biogeography examines how the flood might have influenced the present patterns of distributions of various types of living organisms.
Biomimicry: The Search for Brilliant Design
The West Chester University Professor of Biology, Frank E. Fish, was vacationing along New England's coast frequented by magnificent humpbacked whales. While browsing in a gift shop one day he couldn't help but notice a gifted sculptor’s rendition of one of the splendid creatures and commented to the shop owner that the artist had put bumps on the wrong side of the pectoral fin. The bumps should be…
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,…
What is the Meaning of Kinds in Genesis?
The words kind and kinds that are mentioned in the Creation narrative of Genesis 1:21, 24, and 25. How are we to understand these terms in a modern context? How do they relate to current terms and classifications in biology?
The Riddle of Migratory Birds: Another Evidence of God’s Design
How does one account for bird migrations? Why do they migrate at all? How do they know when it’s time to begin the long journey? What guides their flight path and direction? How do they know their destination, and how do they prepare for the trip?
Ecology, Biodiversity, and Creation: A View from the Top
The complex and vitally essential ecology and biodiversity we find in nature today, at the top of the structural hierarchy of nature, suggest that many interacting organisms would have been required right from the beginning. Only a short-term creation would provide such ecosystem requirements.
