Kodi agalu amaseka bwanji?

Mwambiri, lingaliro la "kuseka" ndi lingaliro lothandizira anthu ndipo limatsimikizira momwe mawu a munthu amachitira, limodzi ndi mawonekedwe oyenera a nkhope.

Ndipo kuseka ndi chodabwitsa kwambiri kotero kuti m'zaka za m'ma 70 za m'ma XNUMX a zaka zapitazo sayansi yapadera inabadwa ku America - gelotology (monga nthambi ya psychiatry), yomwe imaphunzira kuseka ndi kuseka ndi zotsatira zake pa thupi la munthu. Nthawi yomweyo, chithandizo cha kuseka chidawonekera.

Ofufuza ena amakhulupirira kuti kuseka kumatsimikiziridwa ndi zamoyo. Ndipo ana amayamba kuseka popanda maphunziro aliwonse kuyambira miyezi 4-6 kuchokera kugwedezeka, kugwedezeka ndi "cuckoo" zina.

Gawo lomwelo la ofufuzawo likunena kuti anyani onse apamwamba amakhala ndi ma analogue akuseka ndipo palibe wina aliyense.

Mwachitsanzo, kaseweredwe ka anyani apamwamba kaŵirikaŵiri amatsagana ndi maonekedwe a nkhope ndi mawu: nkhope yomasuka yotsegula pakamwa ndi kutulutsanso siginecha ya rhythmic stereotypical sound.

Makhalidwe amamvekedwe a kuseka kwa munthu ali pafupifupi ofanana ndi a chimpanzi ndi bonobos, koma amasiyana ndi a orangutan ndi gorilla.

Kuseka ndi chinthu chovuta kwambiri, chomwe chimakhala ndi kapumidwe kosinthika, komwe kumatsagana ndi mawonekedwe a nkhope - kumwetulira. Ponena za kusuntha kwa kupuma, pamene mukuseka, mutatha kupuma, palibe chimodzi, koma kutulutsa mpweya wochepa wa spasmodic, nthawi zina kumapitirira kwa nthawi yaitali, ndi glottis yotseguka. Ngati zingwe za mawu zimabweretsedwa kumayendedwe oscillatory, ndiye kuti kuseka kwakukulu, sonorous kumapezeka - kuseka, koma ngati zingwe zikukhalabe, ndiye kuti kuseka kumakhala chete, kopanda phokoso.

Amakhulupirira kuti kuseka kudawonekera zaka 5-7 miliyoni zapitazo pamlingo wa kholo la hominin wamba, ndipo pambuyo pake zidakhala zovuta komanso kusintha. M'mawonekedwe ake apano, kuseka kudapangidwa pomwe anthu adayamba kuyenda molunjika, pafupifupi zaka 2 miliyoni zapitazo.

Poyambirira, kuseka ndi kumwetulira kudawuka ngati zolembera komanso ngati zizindikilo za "zabwino", koma monga munthu wopangidwa ndi anthu, ntchito za onse awiriwo zidasintha kotero kuti nthawi zonse samagwirizana ndi malingaliro abwino.

Koma ngati kuseka ndi kumwetulira ndi chiwonetsero cha khalidwe labwino la thupi (ndipo nyama zimakumana nazo), ndiye kuti mu nyama izi zikhoza kukhala zofanana.

Ndipo pamlingo wotere, ofufuza ena akufuna kupeza munthu osati anyani okha, kuti Comrade Pulofesa Jack Panksepp akulengeza ndi udindo wonse kuti anatha kupeza analogue ya kuseka makoswe. Makoswewa, pamasewera komanso okhutira, amatulutsa phokoso la 50 kHz, lomwe limawoneka ngati lofanana ndi kuseka kwa ma hominids, zomwe sizimamveka m'khutu la munthu. Pamasewera, makoswe "amaseka" amachitapo kanthu kapena kukhumudwa kwa anzawo ndi "kuseka" ngati akukomeredwa.

Kuchokera pakupeza kotereku, onse okonda agalu a orthodox adakhumudwa. Ngati chonchi? Makoswe ena amaseka ndi kuseka, ndipo mabwenzi apamtima a munthu amapumula ndi milomo yawo?

Koma pamwamba pa mlomo ndi mutu, agalu ndi eni ake! Mnzake wina, Pulofesa Harrison Backlund, pafupifupi anatsimikizira kuti agalu ali ndi nthabwala komanso kuti amatha kuseka, mwachitsanzo, ataona galu wawo wodziwika bwino akutsetsereka ndi kugwa.

Katswiri wa zamakhalidwe Patricia Simonet amakhulupiriranso kuti agalu amatha kuseka ndi kuseka mwamphamvu ndi zazikulu, mwachitsanzo, pamasewera. Patricia adajambula mawu omwe agalu apakhomo amamveka mwiniwakeyo akamapita kokayenda nawo. Kenako ndidayimba zomveka izi m'malo ogona agalu opanda pokhala, ndipo zidapezeka kuti zimapindulitsa kwambiri nyama zamanjenje. Malinga ndi zimene ananena Patricia, maphokoso a agalu asanapite kukayenda mosangalala tingawayerekezere ndi mmene munthu amafotokozera zakukhosi kwake mwa kuseka mosangalala.

Patricia akuganiza kuti kuseka kwa galu ndi chinthu chofanana ndi kufwenthera koopsa kapena pant.

Ndipo, ngakhale kuti palibe maphunziro aakulu omwe amatsimikizira kuti agalu amatha kuseka ndi kumwetulira, eni ake ambiri a nyamazi amakhulupirira kuti agalu amakhala ndi nthabwala ndipo amakwaniritsa bwino malingaliro awa mu kuseka ndi kumwetulira.

Ndiye tiyeni tiyerekeze kuti agalu amatha kumwetulira ndikuseka, koma izi sizinatsimikizidwebe ndi sayansi yayikulu.
