Charles Darwin pointed to small changes like finch beak size and peppered moth color as visible evidence of an unguided evolutionary process at work.
Although they are not the handsomest or most graceful creatures in the animal kingdom, the Rhinocerotoidea (superfamily) are a fascinating group for research.
They conclude, “there is something besides mutations and survival of the fittest needed to explain evolution.”
The formulation “crazy stuff” of course implicitly suggests that this is a pseudo-problem invented by evil and stupid creationists.
If living systems were deliberately engineered, how good an engineer was the one behind those living systems?
