"Totally random" as distinct from "partially random?"

No, as distinct from locally random. For example, a certain region in the genome is particularly vulnerable to insertional mutations. But within that region, the insertion point is random.

Thankyou for clarifying your use of the phrase, totally random, Nebullis. Accepting that your intended meaning is "locally random," ie. randomity occuring over a limited range of events or elements, does it follow that "undetected explanation" means "no explanation?"
