Approximately how long has the White Crappie (*P. annularis*) existed in some recognizable form?
Answer
10 million years
The deep history of the White Crappie suggests a significant tenure in the aquatic environments of North America. Evidence indicates that White Crappie, in some ancestral or recognizable form, have been present in these waters for an estimated span of 10 million years. This longevity is significant because it indicates a prolonged period of evolutionary separation and refinement following divergence from a common ancestor shared with the Black Crappie (*Pomoxis nigromaculatus*). This extensive timeline underscores the success of their adaptation strategy within the established Centrarchidae lineage.
