Evolution

Cypriniformes include the most primitive of the Ostariophysi in the narrow sense (i.e. excluding the Gonorynchiformes). This is evidenced not only by physiological details, but also by their great distribution, which indicates they had the longest time to spread. The earliest that Cypriniformes might have diverged from Characiphysi (
