Imbwa dziri, zvichida, dzakavanzika zvikuru kubva pane zvesayenzi zvemaonero emhuka. Ichokwadi ndechokuti kwemazana emakore akawanda mavambo acho ndeye musoro wepikisano yesayenzi. Usakakaha kuti imbwa iyi yakasvibisa vertebral chordate yepascental subclass. Izvo ndeyomurairo wezvikara, mhuri yembwa, imbwa yembwa uye inoona imbwa dzemombe.
Ndeapi maonero ezvakabva imbwa?
Kusvika iye zvino, nhoroondo yezvakabva imbwa inowirirana zvikuru nemhumhi, makava, imbwa dzeAustralia nedhoyota uye coyotes. Saka, masayendisiti anotsanangura mavambo embwa yemusha nemazano maviri. Maererano nekutanga, ivo ndivo vana vemhumhi (iyi yaivawo maonero aCharles Darwin), uye vateereri vechipiri chidzidzo kuona imbwa semugumisiro wekuputika makava, mhumhi nemaputi. Munguva ichangopfuura, nharo yechitatu, iyo Karl Linnaeus akaisa mberi, akawanawo kodzero yehupenyu. Mazuva ano zvidzidzo zvemajini zvakasimbiswa zvinoratidza kuti majaya nemapumhi pamazuva ekare aiva nemadzitateguru akafanana, izvo zvakanyangarika.
Izvo ndeyechokwadi kuzivikanwa kuti muBronze Age kusarudzwa kwembwa dzomukati kwaisanganisira zvishanu:
- Mastiffs;
- greyhounds (greyhounds);
- imbwa-sembwa;
- imbwa dzomufudzi;
- imbwa inonzi pointer-like.
Tichifunga nezvekwakabva mhando dzembwa, vatsvakurudzi vakasvika pakugumisa kuti vakaonekwa semugumisiro wekudzimba uye kuwirirana kwezvikara izvi. Nhasi, mhando dziripo dzeimbwa dzakakamurwa kuva mapoka matatu makuru: kusvuta, kushanda, mumba nekunongedza. Kusiyana kune humwe uchapupu hwekutaridzirwa uye kusagadzikana kusarudzwa, iyo inobvumirana zvakakwana nenzira iyo madzitateguru edu ekare akarwira kuti muvepo.
Chero chii chaive, iyo imbwa, uchapupu hwokuti kune huripo hwemakore 25-30 mamiriyoni, yakange iri uye inogara iri shamwari yakatendeka uye mubatsiri wevanhu.
