Accounting Quote by Frank B. Salisbury
“Even something as complex as the eye has appeared several times; for example, in the squid, the vertebrates, and the arthropods. It's bad enough accounting for the origin of such things once, but the thought of producing them several times according to the modern synthetic theory makes my head swim”

He argues that complex organs like the eye appearing multiple times challenges single‑origin explanations and strains the synthetic theory.
In simple terms: Repeated evolution of complex parts questions simple explanations.
