Kangani nguva iwe yawaida kuziva zera remunhu weyaunodikanwa furry asi usati wambove wakanyatso kuve nechokwadi? Iko kutenda kwekuti rimwe imbwa gore rakaenzana makore manomwe edu kwakapararira, asi boka remagenistist masayendisiti anobva kuYunivhesiti yeCalifornia aratidza kuti tanga tichikanganisa.
Uye izvo hazvina kushata zvachose. Kutenda fomula yavakagadzira, ikozvino isu tinogona kunyatsoziva kuti shamwari yedu yemakumbo mana yaizove yakadii dai aive munhu.
Chakavanzika chiri muDNA
DNA, dzimwe nguva inonzi deoxyribonucleic acid, ndiyo chiratidzo chechimwe nechimwe chezvinhu zvipenyu zvinogara mupasi rino, ndosaka masayendisiti akatsvaga fomu iyi nekutsvaga epigenetic mashandiro anonzi methylation. Sezvo ivo vakatsanangura, »Sezvo isu patinokwegura, mapoka emethyl anowedzerwa kumamorekuru edu eDNA, ayo anogona kushandura chiitiko chechikamu cheDNA pasina kuchichinja".
ari mhedzisiro yekudzidza ivo vanoreva kune epigenetic wachi seyimbi yekuyera, ndokuti, kune 'wachi' yatakatakura tese. Wachi iyi yakaenzaniswa neyembwa, kunyanya neyembwa. labradors, uye zvakare neye mbeva. Nei ichi canine ichibereka uye kwete imwe? Huye, icho chinangwa hachisi chimwe kunze kweiyo genome, inoenderana zvakanyanya. Hunhu uhwu hunoita mikana yekuwana majini zvinhu zvinoenderana nehunhu hwakaita sekukwegura zvakanyanya.
Imbwa nevanhu, pamwe havana kunyatsosiyana
Wakambonzwa here kuti imbwa dzinopedzisira dzaonekwa kuhama dzevanhu? Zvakanaka ikozvino pane chimwezve chikonzero chekutenda chinhu chakadai: kana uchifananidza methylomes yevanhu neyaLabradors, Izvo zvakaonekwa kuti zviitiko zvakakosha zvemuviri pakati pezviviri izvi zvinoenderana, uye sekunge izvo zvaive zvisina kukwana, hukama uhu hunosvika kumakonzo.
Kubva pano, ivo vaongorori vakakwanisa kugadzira fomura-yaidikanwa kwazvo iyo inobatsira mamirioni avanhu kuziva kuti shamwari yavo ine makumbo mana yaizove yakadii dai vaive vanhu. Ndiyo inotevera:
yevanhu_age = 16ln (imbwa_age) + 31
Chaizvoizvo zvaunofanirwa kuita ndeizvi wedzera iyo yakasikwa logarithm yezera re canine mumakore ne 16 uyezve wobva wawedzera 31. Nenzira iyi, unogona kuzvionera wega kuti imbwa-yemavhiki manomwe-mbichana yakaita sekunge yaive nemwedzi mipfumbamwe yemunhu, kana kuti ane makore gumi nemaviri Labrador akaita sekunge anga aine makore makumi manomwe emunhu.
Ipo imbwa dzichisvika pakukura pabonde nekukasira, izvo zvinoita kuti makore avo ekuyaruka uye epakati nepfupi, yavo methylation inononoka sezvavanokwegura, saka mabwe akakwanisa kuenderana.
Zvinonakidza, handizvo here?
Handikwanise kunyatsonzwisisa kuti ndingaudza sei zera revanhu veLabrador yangu. yevanhu_age = 16ln (imbwa_age) + 31. Iyi ndiyo nzira iyo iwe yaunopa kuti uzive zera remunhu rinogona kuve
mii labrador. Handizive kana ndichifanirwa kumuwanzira zera na16 ndobva ndawedzera 31. Chandinoziva ndechekuti lab rangu rine makore mapfumbamwe ekuberekwa asi munhu haana zano. Ndinovimba munogona kunditsanangurira, maita basa ..
