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.

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.

Sea Lilies – Another Explosion

The "Cambrian explosion" is a term used to describe the abrupt appearance in the fossil record of major animal phyla, without intermediate forms in lower layers. This pattern of abrupt appearance can be observed for many groups of organisms, including crinoids (sea lilies).

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.

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.
