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.

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 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.

A review of the book, Theistic Evolution: A Scientific, Philosophical and Theological Critique. Theistic evolution, the notion that God is the director of Darwinian-style evolution, is a vain attempt to combine contradictory views of earth history. Published in Origins, n. 65.

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.

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…

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.

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.

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.

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,…

Volcanic outcrops in the Galápagos Archipelago do not appear to provide the wealth of specimens found in other fossil-rich localities around the world. However, fossils are indeed present in the Galápagos Islands. This brief review addresses the where, what, when, and why of fossils in the Galápagos Islands and closes with a discussion of their potential contribution to the development of models on…

The aim of this article is to use the example of Homo naledi to illustrate the distinction between data and interpretations, and to discuss some of the questions a biblical creationist might have in relation to this new discovery.

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.

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, n. 64.

Texbooks describe the fossil record as the ‘best evidence’ for evolution. They claim that the fossil record proves evolution because there seems to be a succession from simpler to more complex life forms, and a succession from marine to terrestrial forms. Charles Darwin suggested that all life has a common ancestor. “All the organic beings which have ever lived on this earth may be descended from some…

During 1833, Arthur Henry Hallam died suddenly and unexpectedly. This would be one of those sad but unremarkable facts of history were it not for his close friendship with Alfred Lord Tennyson. Tennyson spent the next 17 years struggling with the death of his friend. During this time, Tennyson composed “In Memoriam,” a long poem that wrestles with the shock, sadness and despair he experienced and his…

Science is not a straight pathway to total reality and truth, but involves numerous tentative conclusions, reversals of opinion, and inherent uncertainty. Its utility is not that it is always true, but that it is useful and leads to further discovery.

Biogeography is the study of the distributions of living organisms. Biogeographers seek to discover what historical and ecological factors explain why a species lives in one particular area but not in another area. This article examines how the flood might have influenced the present patterns of distributions of various types of living organisms.

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 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…
