@colewd the point is that he is wrong about that. Neutral theory is required to account for complex features. By taking it off the table he is constructing a strawman. That is our point.
I know he mentions molecular clocks and using neutral evolution as a null hypothesis for protein evolution, but my point (as was mentioned earlier) is that Behe clearly doesn’t consider neutral theory to be relevant in a discussion about how complex functional systems actually arose.
the basic, functional, sophisticated molecular machinery of life.
So it’s not that neutral evolution is not important, nor that it is irrelevant to understanding how evolution progresses, but that it is not important in a very particular respect. Its ability to explain complex adaptations.
So qualifications are needed, and that is what I have been saying.
Now Behe argues that in the case of neutral evolution it is in principle incapable because adaptations are by definition selectable, where neutral mutation are by definition not. In other words, Behe offers an argument and it seems to me the thing to do would be to address his argument rather than just dismissing it as irrelevant.
Why wouldn’t neutral evolution contribute to complex adaptations?
Beneficial adaptations that require prior neutral adaptations are selectable. Increases in complexity can also be due to neutral mutations, such as the duplication of Hox genes or any genes for that matter.
That’s what I said Behe thinks, also directly quoting Behe.
Exactly, and I think this is just fundamentally flawed. A “neutral mutation” is not a fixed identity. Long story short, neutral mutations can become adaptive down the line, so understanding the spread of these “potential adaptive mutations” is critically important. I think that “constructive neutral evolution” has been brought up here recently, and I also think that it’s a pretty glaring oversight that Behe doesn’t mention this by name, or even reference people like Arlin Soltzfus.
Why I think it’s important that Behe dismisses the importance of neutral theory to the evolution of complex functional systems without mentioning a fairly well-known model for the contribution of neutral theory to the evolution of complex functional systems?
