Caanihii ugu da 'weynaa ee eeyaha ayaa baadhay koox cilmi-baarayaal ah oo ay hoggaaminayaan Petra Savolainen, oo ah borofisar ka tirsan Waaxda Zoolojiga ee Machadka Royal College of Technology.
Tallaabooyinka ugu horeeya ee wax lagu barto
Si loo helo macluumaad la isku halleyn karo 2004, DNA-da mitokondrial (oo laga dhaxlay habka dumarka) ee eeyaha casriga ah iyo awoowayaashooda duurjoogta ah ee yaxaas ah ayaa la barbar dhigay. Natiijada ka soo baxday xogta la helay, ayaa la mid ah xayawaan badan oo woxoogaa ah oo qaab-dhismeed DNA ah lagu ogaaday 14 nuuc ee eyga.
Noocyada hore ayaa ka tagaya horumarka laga soo bilaabo awoowgooda dhawr kun oo sano. Helitaanka eeyga ugu da 'weyn ee eey cuno waa qiyaas ahaan 15,000 oo sano. Si kastaba ha noqotee, qaar ka mid ah bayoolajiistu waxay aaminsan yihiin in ilaha hore ee eeyaha ay kala go'een geedka inta badan.
Saynisyahanno Robert Wayne ayaa aaminsan in muuqaalka nooca hoyga gudaha ah uu dhacay wax badan ka hor intii aan la dhigin qaab nololeed oo dabiici ah dadka (ilaa 10,000 - 14,000 oo sano ka hor). Markii hore, saynisyahannadu waxay rumaysteen in dadka asaasiga ah aysan bilaabin xayawaanka guryaha. Si kastaba ha ahaatee, sida laga soo xigtay Robert Wayne, eeyaha ugu horreeya waxay u muuqdaan 100,000 sano ka hor ama wax badan oo hore.
Cilmi-baarayaal badan ayaa aaminsan in eeyga ugu caansan eek u yaal Bariga Aasiya. Inta lagu guda jiray cilmi baarista, waxay ahayd halkaa in kala duwanaanta hidde-wanaaga laga helay, taas oo si muuqata u liidata gobollada kale iyo qaaradda.
Eeyaha ugu weynaa
- Akita Inu (Japan)
- Alaskan Malamute (Alaska)
- Afghan Greyhound (Afgaanistaan)
- Basenji (Congo)
- Lhasa Sidoo kale (Tibet)
- Pikenes (Shiinaha)
- Saluki (Bisha Cas ee Bariga Dhexe)
- Samoyed Dog (Siberia, Ruushka)
- Shiba Inu (Japan)
- Siberian Husky (Siberia, Ruushka)
- Tibetan Terrier (Tibet)
- Chow Chow (Shiinaha)
- Sharpei (Shiinaha)
- Shih Tzu (Tibet, Shiinaha)
Si kastaba ha ahaatee, jawaabta kama dambaysta ah ee su'aasha, eeyaha ayaa ah kuwa ugu caansan, waxaa la heli karaa marka dhammaan noocyada casriga ah ee la baaro.
