In short, grasping food objects and small-diameter supports were probably key factors in the development of primate manual prehension. |
Again, how far down you push a cultural background depends upon how far down you are willing to push individual prehension. |
After prey capture is initiated, jaw prehension is used to ingest the prey item. |
Prey were captured in water using jaw prehension, triggered by visual or tactile information. |
Jaw prehension is common in aquatic frogs, often in combination with abortive tongue protraction, but suction feeding is present only in pipids. |
So prehension is a ferment of qualitative valuation which need not necessarily be conscious. |
