i About the BioLogos Forum

The BioLogos Forum is designed to foster a serious and comprehensive discussion of Christian faith and the sciences. We believe that charitable engagement of different perspectives within the Church helps sharpen our thinking and deepen our commitment to the truth that is hidden in Christ. So while many of the articles and videos under the distinctive Forum banner come from BioLogos staff and Senior Fellows, we feature a range of voices, including those that disagree with us and with each other. Unless otherwise noted, views expressed are those of the authors, not necessarily of The BioLogos Foundation. You can read more about what we believe here, and join the conversation in the comments section at the end of each post.

The Evolutionary Origins of Genetic Information, Part 1

The Evolutionary Origins of Genetic Information

Join astrobiologist Stephen Freeland for a look into the nature of information and the origins of life on earth. (These posts were originally published as a paper in the ASA’s academic journal, PSCF, and are reprinted here with permission.)

The Evolutionary Origins of Genetic Information, Part 1

At first sight, both macro-mutationism and creationism seem similar. Both propose a cut-off point for the degree of genetic change that evolutionary theory can explain, and both propose a new cause must be added to explain genetic differences beyond this cut-off. Where the two propositions differ for science is in their potential for tests.

The idea that some sequences of DNA cannot be produced by natural processes owing to the information they contain has no empirical support from modern genetics. In fact, quite the reverse.

The Evolutionary Origins of Genetic Information, Part 3

It is true that at present, evolutionary science does not have a clear, detailed and well-accepted explanation for how the Central Dogma of molecular biology emerged. But does that mean it is time to embrace Intelligent Design as a better approach?

The Evolutionary Origins of Genetic Information, Part 4

…everything points towards DNA being the last arrival out of the 3 fundamental biomolecules: DNA, RNA and protein . DNA is made by complex, genetically encoded protein enzymes without a ribozyme in sight. The individual building-blocks of DNA (deoxynucleotides) are made by taking and modifying a nucleotide of RNA. Again, all this is exactly what we would expect if DNA evolved from RNA, after genetically encoded proteins had already entered the picture.
