| define a signal | energy or matter generated by the display or action of one organism (the signaller) that is (selected evolution) for its effects in influencing the probability pattern of behaviour of another organism (the receiver) via its sensory-nervous system in a fashion that is adaptive to one or both parties |
| what is the example of signal found in the californa ground sqauirel | it flags its tail to warn snake predators, heating up its tail only in the prescence of snake s |
| how might signals have evolved | through ritualization andsensory expoiation/ sensory bias |
| what are the sensory cue that wolves are said to produce | Baring teeth Urination as autonomic fear response Intention movements Ambivalent behaviour |
| how are ritualized sensory cues made | increasing the likelyhood through selection of cues. generally makes the animals intentions more clear. the cue is seleced for decreased ambiguity |
| in the sense of ritualization how did the peacocks tail feathers get bigger | Food enticement behaviour starts with the bird going down to get food and pushing the tail feathers up the femails where attracted to the tail feathers so the tail feathers got bigger |
| what was the example of ritualization in masked birchcaterpillars | Vibratory display (anal scraping, mandible drumming, mandible scraping) to intruders |
| what is important about hte Tethea species in relation to the birchcaterpillar | its very similar but doesnt have the anal oar so it can't produce the scrpaing sound |
| how did the ritualiztion evolve in the birchcaterpillars | the walking signal evolved first then the scraping signal. if over catapilars could more easily sense the walking then conflict was less likely |
