Isu vanhu tine seti-yakakwana yezvishandiso zvekuzvidzivirira nazvo pakutyisidzirwa. Kunzwa kwedu kwakadzama kunotora kurira kusingaite muuswa, uye maitiro edu ekuona anoramba akadzidziswa kumberi, achigadzira kunzwisisa kwakadzama apo maziso edu anoshanda pamwe chete, mumwe nemumwe uye nedzimwe pfungwa dzedu. Hazvifanire kushamisa kuti Lynne Isbell paaipfuura nemuKenyan glade muna 1992, akangomira pamusuwo chaipo pemhungu yakanga yagadzirira kurohwa.

Anthropologist kubva kuYunivhesiti yeCalifornia Davis, Isbell akakura achida kuziva mushure mechiitiko ichi. Akashamisika kuti sei huropi hwake hwaiziva kumisa kufamba kwese, kunyangwe dai akange asina nguva yekuziva pfungwa mumusoro make: Nyoka inouraya iri pamberi pangu, ndinofanira kumira kufamba. Huropi hwake hunoita otomatiki, hwakakwenenzverwa hwemhinduro yekutya hwakatora nzvimbo. Chiitiko ichi chave chakurudzira makumi emakumi emakore ekutsvagisa muIsbell's lab, uye yakawana sainzi yekurapa yave pedyo nekunzwisisa vanhu 'uye primates' pfungwa dzekutya kutya.

"Pakutanga ndaifunga kuti raive rombo rakanaka," akadaro mubvunzurudzo ichangoburwa neNPR. "Asi iye zvino ndine chokwadi chokuti haisi rombo rakanaka. Icho chiratidziro chemakore emamiriyoni e60 enhoroondo yekushanduka-shanduka inoshanda pakuona kwangu."

Zvichangobva kuwanikwa naIsbell zvinovhenekera nzvimbo iri muuropi inonzi pulvinar. Kubva pashoko rechiLatini rokuti pulvinus rokuti "cushion," bundle re nuclei rinogara pasi pe thalamus, pakati peuropi. Inongowanikwa muvanhu, primates, uye tsoko. Masayendisiti anotenda kuti maronda enzvimbo iyi anogona kukonzera kushomeka kwekutarisisa uye kuregeredza syndromes. Tsvagiridzo yaIsbell inowedzera kune yayo runyorwa rwemabasa, sezvo zvidzidzo zveprimate pulvinar zvichiratidza mhinduro inogona kuitika yekusaziva kwake muKenya muna 1992.

Akawana, semuenzaniso, kuti maprimates munzvimbo dzepasirese uko nyoka dzisinganyanyi kuwanda dzinowanzove nekuona kwakashata. Tsoko dziri kuMadagascar dzinoona zvinotyisa, anodaro, uye haisi tsaona: Madagascar haina nyoka dzine uturu.

Kubvisa zvichemo izvi muhumbowo hwesimba, Isbell akagadzira bvunzo inosanganisira tsoko mbiri idzo, mukufungidzira, dzingadai dzisina kumbobvira dzaona nyoka. Akabatana nevatsvakurudzi vekuJapan ndokuisa macaques maviri pamberi pezvidzitiro zvairatidza nyoka dzinotyisa, kana mifananidzo yakanaka yemaoko, zviso, uye maumbirwo. Vatsvakurudzi vakaona kuti kubva mu100 neuroni dzakapfura pamberi pechifananidzo chimwe chete, 40 muzana yetsinga dzakaputika apo mufananidzo iwoyo wairatidza nyoka. Boka guru raitevera rakanga riri zviso, pa29 muzana.

"Kune ma neuron anonzwa zvakanyanya kumifananidzo yenyoka uye anonzwa zvakanyanya kwavari kupfuura zviso zvezviso," Isbell akaudza NPR. Chikamu chetsananguro ndechekuti vanhu nemaprimate vane masisitimu avo ekuona akatarisana mumuviri.

"Tine maziso edu akatarisa mberi," anodaro. "Tine maonero edu akadzama akadzikama. Tine maonero akanaka kwazvo, akanakisisa munyika inoyamwisa. Tine maonero emavara. Saka panofanira kuva netsanangudzo yazvo."

Tsvagiridzo yaIsbell inoisa hwaro hwakakosha hwekudzidza kuti huropi hwemaprimates hunokura sei pfungwa yekutya. Nepo tsvakiridzo yapfuura yakaratidza kuti Malagasy lemurs haaratidze mhinduro dzekunze dzekutya kunyoka, pamwe nekuona kuti hadzina huturu, zvakawanikwa naIsbell zvinopindirana munharaunda yese yesainzi seane hunyanzvi.

"Pave paine vanhu vazhinji vaifungidzira kuti panofanira kunge paine chinhu chakadai chiri kuitika," Sue Mineka, purofesa wezvepfungwa dzekiriniki paNorthwestern University, anotsanangura. Tsvagiridzo yaMineka inoburitsa maburi mudzidziso yaIsbell yekutya kwekuzvarwa, kunyangwe achibvuma kuti pane zvakawanda zvinowanwa kubva muchidzidzo chazvino.

"Tinoziva kuti marudzi mazhinji etsoko anogara achitya nyoka kana kuti anotya nyoka nyore," akaudza Agence France-Presse. "Izvi zvinopa nzira inobvira. mabhuku."
