However the idea that biological systems as complex as an cell evolved WITHOUT a designer violates the law of probability. That is the likelihood of a cell occurring by chance through some designer-free evolution, without a purposeful designer is so vanishingly small as to be indistinguishable for all practical purposes from zero.
The following online lecture kind of changes that estimate of probability, doesn't it?
Making Genetic Networks Operate Robustly: Unintelligent Non-design Suffices, by Professor Garrett Odell
Abstract: Mathematical computer models of two ancient and famous genetic networks act early in embryos of many different species to determine the body plan. Models revealed these networks to be astonishingly robust, despite their 'unintelligent design.' This examines the use of mathematical models to shed light on how biological, pattern-forming gene networks operate and how thoughtless, haphazard, non-design produces networks whose robustness seems inspired, begging the question what else unintelligent non-design might be capable of.
