Is There a Scientific Conflict Between the Theory of Darwinian Evolution and the Fossil Record?

Darwin saw evolution as a slow and steady process with species gradually transforming into new species over long time. He thought that the fossil record should provide evidence for his theory. However, the needed evidence proved to be elusive.

Understanding the Theory of Evolution

The theory of evolution has pervaded most fields of knowledge. Therefore, it is important to know the fundamentals of this theory in order to understand how this ideology influences interpretations of data from nature and differs from the biblical creation model of the origin of life forms.

Cnidarian Venom Evolution: Nothing New Under the Sun

Cnidarians appear to have recruited as toxins the same kinds of proteins recruited by many other venomous animals. However, toxin diversity within groups of organisms does not appear to be related to the alleged evolutionary history of the various groups.

Evolution: The Seen and the Unseen

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.

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.
