Fig. 5: Hypothesis of the elaboration of the PAFF to paired fins.

From: A median fin derived from the lateral plate mesoderm and the origin of paired fins

Fig. 5

Simplified evolutionary scenario of vertebrates showing the presence of a PAFF and subsequent modifications leading to paired fins. Dashed lines and dagger symbols indicate extinct lineages, and solid lines indicate extant lineages. PM-derived fins and fin folds are in cyan, while LPM-derived fins are in pink. Larval PAFF is hatched. Black arrows indicate the position of the anus.
