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.

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.

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…
