Hi John T Mullen,
I must admit the statement in point (2), “…a genetically-based view of sin enables Christians to view evolutionary biology as providing some support,” leaves me somewhat astonished – I am taking this as a meaningful scientific statement, and in that context, I would ask you to identify some “sin” gene, or genetic sequence that we could equate with the Christian meaning of sin. This is a fair question, as the burden of proof or demonstration is with those who make such statements. I do not see any threat or conflict in this, as materially we are made of the same “stuff” as the rest of the world; nor am accepting that biology has scientifically isolated a selfish gene. Genetically based statements of this type are also a simple and unsubstantiated form of story telling, as providing an intellectually satisfying narrative for anti-theists.
On your points (3A and 3B) a gaping gap remains in your assertions, and I have yet to read from anyone, a clear and scientifically valid basis for the unique place of humanity in the bio-world, and indeed in every sense the unique and counter-ecological position mankind has displayed and continues to do so. It is well enough to claim something is settled, but for a scientifically sound theory, it must account for the obvious, as well as any fragmentary data people collect. I am aware of the “great leap” hypothesis, and other pseudo-scientific notions on brain activity, and find these unsupported in any meaningful way – anyone can make a claim and provide an argument; from the absence of any comment from you on the criteria I made for settled science, I may need to assume that you adopt some other basis for accepting speculation as scientific fact.
Thus to summarise: (a) the argument from biology lacks a scientific basis because there is no identifiable gene or such, that directly links human “nature” (or attributes) with sin (and as a result, we cannot make theological implications), and (b) your link to a small population and some genetic sequence that leads people to “common descent” for humanity, is unable to provide an explanation for the central tenet that needs explaining, the unique impact of humanity on the ecology of this planet (I claim my point is easily tested and examined scientifically, you link between the notion(s) of descent and the place of humanity in the ecology cannot).
My summary should make my point clear – the theology of the Christian faith does not need to be modified, or Christians question their faith, when carefully and unemotionally examining the claims of evolutionary biology.
Your statement regarding some type of evil in nature is also without a scientific basis – we may examine this theoretically by looking to science to answer the question(s) implied in this statement:
“If human kind were to be removed in an instant from planet earth, the planet would flourish and every type of life would grow until the planet would be bursting with life. Instead every day we are counting the extinction of more species, all due to human impact.”
Again there is ample data to support the above statement. Flourishing life is not evil, nor is an ecologically balanced planet – this is good. Destroying species and causing suffering by human sin is evil. It is wrong to look to evolutionary biology for an understanding of the Christian faith.
