Biology Quote by Lee Spetner
““Neo-Darwinians do cite some examples of evolution they claim the NDT explains. Natural selection can indeed account for the replacement of light-colored moths with dark ones when the lichens get covered with soot. But no one has shown that the difference between the two kinds of moths arose by a random mutation. The key point of randomness is not tested by those data.””
About This Quote
Source Book: Evolutionary Biology Critique, 2010
The author argues that while natural selection explains some changes, the randomness of mutations, especially in moth coloration, lacks direct evidence, challenging certain evolutionary claims.
In simple terms: Random mutation evidence is missing in some evolutionary examples.
Key Takeaway
Seek empirical proof for mutation randomness.
