Tim Standish: Simpler systems do not necessarily come first because simple can be a lot harder to come up with than complex. Yes, that seems counterintuitive, but the history of technology bears that out. In some ways you could say the same about art.
Standish: The impossible task that Darwinists have is not just to show that what they propose is possible, it is to show that this is what actually happened, not just with one or two genes or traits or morphologies or whatever else you want to look at, but with the whole lot. They are masters at picking ambiguous and exceptional examples and treating them as if they are the rule.
Friends had some doubts, reading this story…
Standish: If the nitrogen cycle isn’t established within a certain time, nitrogen will be removed from the atmosphere and the surface will become rich in nitrate (bad) or, in a reducing atmosphere, ammonia (really bad). The bottom line is that there are speculations that probably get around this, but it is one more needle that has to be threaded for chemical evolution to produce the first life, or a problem for the first life to quickly take care of.
Timothy Standish: The authors seem to have found that if you already have alleles that adapt you to a certain set of conditions, then you will be able to rapidly adapt to those conditions. The speed is impressive, but you could argue that the speed with which natural selection can work is not the real question. The real question is, “How fast can those alleles that make organisms more fit arise de novo in a population that doesn’t already have them?”
