Synthesizing Life in the Laboratory: Why is it not Happening?

Laboratory abiogenesis is one of the ultimate goals of experimental biology. The most formidable barrier to create living matter in the laboratory is not the complexity of the cell, rather the absolute requirement for non-equilibrium steady state for all chemical reactions. Current synthetic biology technologies cannot yet produce cells, which harbor chemical systems in non-equilibrium steady-states.

How Can Miracles Be Possible?

The denial of miracles is a recent phenomenon based on how modernity has chosen to understand the workings of nature and what is possible in it. Belief in a personal God (theism), however, argues that through God’s actions, an event that is naturally impossible can be transformed into a real historical event. This article was originally published in Perspective Digest, v. 24/2.

Biblical Creation and Ancient Near Eastern Evolutionary Ideas

Ancient Near Eastern views should be considered part of the history of the idea of evolution. The biblical Creation account, in describing the divine actions through which God actually brought the cosmos into existence, was likely deconstructing the alternative theories or speculations of origins available in the Ancient Near East. Consequently, the biblical narrative can be used as well to deconstruct contemporary cosmogonies and evolution. This article was originally published on Perspective Digest, v.24/3.

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.

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…
