Nekududzira genetics muvanhu nehove, masayendisiti iye zvino anotenda kuti mutsipa - chikamu chidiki chemuviri pakati pemusoro wako nemapfudzi - chakapa vanhu rusununguko rwakawanda rwekufamba zvekuti rwakaita basa rinoshamisa uye rakakura mukushanduka kwehuropi hwemunhu. kuNew York University neCornell University neuroscientists mune online magazine Nature Communications (Chikunguru 27, 2010.)

Vesainzi vaifungidzira kuti zvimbi zvepectoral muhove uye kumberi (mawoko nemaoko) muvanhu hazvina kuvharwa - kana kugamuchira tsinga - kubva mutsinga dzakafanana. Pamusoro pazvo, zvimbi zviri pahove nemaoko ari pavanhu zvinoita kunge zviri panzvimbo imwe chete pamuviri. Hazvina kudaro.

Munguva yekuchinja kwemadzitateguru edu kubva kuhove kuenda kuvagari vepasi izvo zvakaita kuti pave nemhuka dzakati twasu, tsime rema neuron anodzora zvakananga makumbo emberi aifamba kubva muuropi kuenda kumusana, sezvo torso yaisimuka kubva mumusoro ichipihwa mutsipa.. Nemamwe mashoko maoko evanhu, semapapiro ezviremwaremwa neshiri, akabva aparadzana nemusoro akaiswa pamutumbi wezasi pemutsipa.

"Mutsipa unotenderwa kuvandudza mafambiro uye dexterity munzvimbo dzepasi uye dzemuchadenga," anodaro Andrew Bass, Cornell purofesa we neurobiology uye maitiro, uye munyori pabepa. "Ichi chitsva mubiomechanics chakashanduka-chibata-ruoko nekuchinja kwemaitiro etsinga dzinodzora nhengo dzedu."

Bass akatsanangura kuti iyi nhanho isingatarisirwe yekushanduka-shanduka kwepurasitiki ingangove inokonzeresa kushamisa kwehunyanzvi hwepamberi - kubva pakushandiswa kwavo mukubhururuka neshiri kusvika pakushambira nemawhale nema dolphin, uye kuridza piyano kuvanhu.
