What finding often results when comparing the deep genetic separations in *C. oreganus* molecular data with current subspecies classifications?

Answer

A mismatch, where genetic structure reveals splits predating morphological differences.

A common outcome when modern molecular techniques are applied to groups like *Crotalus oreganus* is a discrepancy between deep genetic separations and established subspecies classifications based on observable traits like scale pattern or coloration. Genetic data often reveals ancient separation events that predate easily recognizable morphological traits. Consequently, it is frequently found that some recognized subspecies may share closer genetic affinity with populations currently outside their classification boundary than with other populations currently grouped within that same subspecies, demonstrating the limitations of relying solely on external appearance for evolutionary classification.
