They do(cid:374)"t ha(cid:448)e so(cid:373)ethi(cid:374)g that u(cid:374)derlies la(cid:374)guage. According to tomasello, vocalizations are: more developed in monkeys than apes, largely involuntary and not intentional. The (cid:448)ocalizatio(cid:374)s of curre(cid:374)tly li(cid:448)i(cid:374)g pri(cid:373)ates do(cid:374)"t look (cid:373)uch like la(cid:374)guage at all. Monkeys have different calls for different predators. Ape gestures are closer to human language than are ape/primate vocalizations: they"re (cid:448)olu(cid:374)tary, i(cid:374)te(cid:374)tio(cid:374)al (cid:894)(cid:374)ot produced auto(cid:373)atically i(cid:374) respo(cid:374)se to stimulus) Ape gestures are voluntary, intentional signals: many individual differences in gestural repertoire of different individuals of the same species, even within the same group. An individual performs first step in a behavioral sequence, this is enough to elicit response from others. Adaptations by a species (wolves baring teeth) Wolves who conspicuously prepare for biting by baring their teeth and growling have an adaptive advantage. Over evolutionary time, this results in the genetic fixation of intention-movement displays performed invariably in specific emotional and/or social circumstances. Are learned by an individual (chimp arm-raise)
