Onto‐ and phylogenetic origins of behavioral signals. Most behavioral signals are derived from cues that evolve into signals through intention movements or displacement acts. Through invention and subsequent social transmission, some cues or other invented behavior patterns with communicative effect may become cultural, and may or may not subsequently become manifested in a species' innate repertoire. Very few signals are derived from ontogenetic ritualization, which may or may not become group‐ and species‐specific (dotted paths).
