Before genetic analysis refined taxonomy, P. obsoletus and relatives were often grouped under which genus?
Answer
Elaphe
Historically, prior to the extensive genetic analyses that informed modern phylogenetic classification, many species now placed in *Pantherophis*, including the ancestor of the Western Rat Snake, were historically grouped under the genus *Elaphe*. This genus traditionally contained Old World rat snakes, suggesting a morphological similarity that led taxonomists to group them together initially. The subsequent reclassification into *Pantherophis* was necessary because genetic data revealed that the New World rat snakes, like *P. obsoletus*, constitute a distinct and separate evolutionary lineage compared to their Eurasian counterparts, even if they share superficial characteristics such as diet and climbing behavior.
