Extended Data Fig. 4: Correspondence analyses graphs of excavated areas and fish taxa (a), and of excavated areas and representation of skeletal elements (b).
From: Evidence for the cooking of fish 780,000 years ago at Gesher Benot Ya’aqov, Israel
a, Correspondence analysis graph showing the association between archaeological horizons and fish taxa (Area A; NISP = 9,206, Area B; NISP = 30,318). The two dimensions, the location of the fish remains (51.4%), and the cause of death (natural - Area A, or cultural- Area B; 45%), almost equally account for the data set variation. b, Correspondence analysis graph showing the association between AH and skeletal elements. The deposition agent (natural or cultural) accounts for most of the variation in the data set (80.8%). This derives from the unique preservation pattern observed in the eight superimposed AHs of Area B (II-6 L1–7), that is, comprises almost exclusively cyprinid pharyngeal teeth. Bottom: Representative fish remains recovered at GBY areas A and B (from left to right): Cyprinidae pharyngeal teeth, L. longiceps 1st molariform tooth, C. canis pharyngeal jaw, Clariidae frontal bone, Cyprinidae pectoral spine, and Cichlidae dorsal fin spine.
