What primary diagnostic tool led to the initial grouping under Pantherophis obsoletus?
Answer
Morphological similarity, like coloration and scale counts
The initial classification and subsequent taxonomic confusion surrounding *Pantherophis obsoletus* stemmed from historical scientific practices where observable traits were the primary basis for defining species boundaries. Herpetologists heavily relied on visible characteristics such as coloration, general pattern, and scale counts to delineate species. This reliance on superficial resemblance often resulted in grouping snakes that looked alike or occupied adjacent territories under the single banner of *P. obsoletus*, creating what is now understood as a species complex before molecular techniques allowed for deeper evolutionary insight.
