Many times people try to divorce the origin of Life and Evolution as two separate issues. However this is mistaken and misleading.
(This article is the second in a series of articles on evolution, particularly neo-Darwinian evolution. The first article in the series can be found HERE.)
“Darwin never mentioned life’s origin!” This is a common argument one might hear on various blogs and boards when discussing the Origin of Life (OOL) in relationship to neo-Darwinian evolution (NDE). “You have to have life before it can evolve.” However, scientists in the field and professors who teach the subjects realize that the two subjects are inextricably linked. In this article I will attempt to show how one can not simply dismiss the subject of OOL when discussing NDE.
First witness: Wikipedia. I don’t typically recommend Wikipedia for research, especially when looking for information that is controversial or politically charged. However, for subjects for which there seems to be consensus, it can be a good starting place. In the Wikipedia article on evolution, under the evolutionary history of life, the first sub-heading is “Origin of Life“.
Next, we have a well reasoned article written by Greg Laden, at Science Blogs. Mr. Laden concludes:
Most models for the origin of life are very Darwinian. Most have some selection going on, most have some diversification going on, and all, by necessity and definition, have change over time going on. And, it is organic change, because the stuff of life before the primordial animation was organic stuff.
The origin of life is part of evolutionary biology. (emphasis mine)
Tell us what you really think, Greg. Finally, I present to you a website located on the University of California, Berkeley, web site. This series of web pages is dedicated to “understanding evolution for teachers.” Part of this series is on-you guessed it-the Origin of Life. So, now at least you have a few handy resources to refer to when someone tells you that evolution and the origin of life are two separate issues.
The thing is, why do they make such a fuss about it? In a recent article I posted, “Is Science Opposed to Christianity?“, I was told not once but twice that the two subjects can not be discussed jointly: “these are 2 completely different scientific doctrines” and “you confuse abiogenesis with evolution.” I provided these same references for the gentleman who leveled these charges, but as happens so many times in these types of discussions, he simply deflected and refused to acknowledge the evidence offered.
Here are my thoughts on the equivocation: proponents of NDE know that when it comes to OOL, they have no footing whatsoever. As I quoted in my article “The Origin of Life: A Pause for Clarity“, prominent OOL scientist Eugene Koonin woefully stated:
“However, the origin of life—or, to be more precise, the origin of the first replicator systems and the origin of translation-remains a huge enigma, and progress in solving these problems has been very modest — in the case of translation, nearly negligible… However, these advances remain only preliminaries, even if important ones, because they do not even come close to a coherent scenario for prebiological evolution, from the first organic molecules to the first replicator systems, and from these to bona fide biological entities in which information storage and function are partitioned between distinct classes of molecules (nucleic acids and proteins, respectively).”
“In my view, all advances notwithstanding, evolutionary biology is and will remain woefully incomplete until there is at least a plausible, even if not compelling, origin of life scenario.” Koonin, Eugene V. (2012). The Logic of Chance: The Nature and Origin of Biological Evolution. , Pearson Education, Inc., Publishing as FT Press Science, New Jersey, page 417. (Emphases mine)
Well said, Dr. Koonin. Notice how low he sets the bar- “plausible… if not compelling.” Conversely, proponents of NDE do feel like they are on solid ground when discussing the neo-Darwinian synthesis. After all, it is widely accepted, there seems to be overwhelming consensus in the scientific community, and it is universally taught in the public school system. However, over the next few articles I will attempt to show some of the areas in which NDE falls far short of explaining life as we see it today.
I’d love to discuss these things with you. Any questions and comments that are in line with this page’s Commenting Policy will be published and responded to (to the best of my ability).
