Evolution’s weaker claims
February 25, 2013
[UPDATE: I have added an addendum at the end.]
It is refreshing to read a scientist’s perspective on the evolution/creationism debate: An Insider’s View of the Academy (ht: Vincent Torley). The author is James Tour, the Chao Professor of Chemistry at Rice University.
Tour is questioning the scientific academy’s confidence in macro-evolution. To be clear, this is not an apologia for either the Intelligent Design community, much less the Young Earth Creationism folks. He expressly rejects both. Rather, it is an honest assessment of the academy’s willingness to recognize certain weaknesses in the evolutionary theory. Here is a snippet:
Although most scientists leave few stones unturned in their quest to discern mechanisms before wholeheartedly accepting them, when it comes to the often gross extrapolations between observations and conclusions on macroevolution, scientists, it seems to me, permit unhealthy leeway.
…It is not a matter of politics. I simply do not understand, chemically, how macroevolution could have happened. Hence, am I not free to join the ranks of the skeptical and to sign such a statement without reprisals from those that disagree with me? Furthermore, when I, a non-conformist, ask proponents for clarification, they get flustered in public and confessional in private wherein they sheepishly confess that they really don’t understand either. Well, that is all I am saying: I do not understand.
He goes on to offer warnings to his younger colleagues and students who share his concerns about the integrity of the scientific academy on matters pertaining to macro-evolution. This unwillingness to challenge the mechanics of macro-evolution is, it seems to me, a mirror image of the fear and protectionism in certain segments of evangelicalism. There are strengths, to be sure, in the overall evolutionary paradigm, namely the evidence for an old earth. Yet, the mechanics of the evolution itself between species, and especially the emergence of life, is notably weaker. John Lennox, Professor of Mathematics at Oxford, touches upon this in his excellent (and highly accessible) book, Seven Days that Divide the World. With scientists like Tour and Lennox, the dialogue between science and theology can be far healthier than is found, especially at certain seminaries. It will also bolster the credibility (both scientific and theological) of those of us who refuse to be pushed into either the strict Darwinian Evolution camp or the Young Earth camp.
Addendum — Just to be clear, I am not offering this as any sort of proof against macro-evolution or against the viability of a theistic evolutionary framework. Much less would I argue for a “God of the gaps,” which is the danger of offering these sort of questions about macro-evolution. In the spectrum from YEC to Theistic Evolution, I have always leaned heavily toward the latter but not uncritically, and I find the mediating positions to be fascinating (OEC and Progressive Creationism). As a theology student and seminarian, I just want to see a more productive dialogue between evangelicals and the scientific establishment. I’ve criticized the former several times on this blog (e.g., here and here and here); now I am offering a criticism of the latter.
