Adaptation Quote by Ricky Ray
“Darwinian evolution is slow and gradual, step by step. Such an evolution can explain micro-evolution but not macro-evolution. For example, how did the eye evolve? The idea behind Darwinism is that organisms adapt, and that nature selects only those genetic changes which are the mutations that serve a good purpose for adaptation. So taken this way, the eye cannot develop gradually because one-thousandth or one-millionth of an eye would be of no value for survival. So generally this question rules out Darwinism as an adequate theory for macro-evolution.”
About This Quote
The quote argues that gradual, stepwise evolution cannot account for complex structures like the eye, suggesting a limitation of Darwinian explanations for large‑scale changes.
In simple terms: Gradual evolution can’t explain big changes like the eye.
Key Takeaway
Question the completeness of gradualist evolution.

A Different Perspective
Evolutionary theory also includes mechanisms like gene duplication and exaptation that can produce complexity.
![“[Evolution] doesn't mean God-guided, gradual creation. It means unguided, purposeless change. The Darwinian theory doesn't say that God created slowly. It says that naturalistic evolution is the creator, and so God had nothing to do with it.” quote by Philip Johnson](https://sms4smile.com/quotes/img-quotes/bfa/philip-johnson-10392_change_evolution-doesn-t-mean-god-guided-gradua_2809135.jpg)
