Girafi ndi nyama yodabwitsa, yokongola kwambiri, yokhala ndi miyendo yopyapyala komanso khosi lalitali. Iye ndi wosiyana kwambiri ndi oimira ena anyama, makamaka kutalika kwake, komwe kumatha kupitirira mamita asanu... izo nyama yayitali kwambiri pakati pawo okhala pamtunda. Khosi lake lalitali ndi theka la kutalika kwa thupi lonse.
Chidwi cha ndira chimabuka pakati pa ana ndi akulu, chifukwa chiyani amafunikira miyendo yayitali komanso khosi. Mwina padzakhala mafunso ocheperako ngati nyama zomwe zili ndi khosi lotere zikadakhala zachilendo kuzinyama zathu.
Koma akadyamsonga ali ndi mawonekedwe ena osiyana kwambiri ndi nyama zina. Khosi lalitali limakhala ndi ma vertebrae asanu ndi awiri, ndendende kuchuluka komweko kwa nyama iliyonse, koma mawonekedwe ake ndiopadera, amatalikirana kwambiri. Chifukwa cha izi, khosi silimasintha.
Mtima ndi waukulu, chifukwa ntchito yake ndikutumiza ziwalo zonse ndi magazi, ndipo kuti magazi afike kuubongo, amayenera kukwezedwa ndi mita 2.5. Kuthamanga kwa magazi chithaphwi pafupifupi kuwirikiza kawirikuposa nyama zina.
Mapapu achimphona nawonso ndi akulu, pafupifupi kasanu ndi katatu kuposa wamkulu... Ntchito yawo ndikutulutsa mpweya panjira yayitali, kupuma kwake kumakhala kotsika kwambiri kuposa kwa munthu. Ndipo mutu wa nyamalikiti ndi waung'ono kwambiri.
Chosangalatsa ndichakuti, akadyamsonga amagona nthawi zambiri atayimirira, mutu wawo ukupuma pa croup. Nthawi zina akadyamsonga amagona pansi kuti apumitse miyendo yawo. Nthawi yomweyo, zimakhala zovuta kuti apeze malo a khosi lalitali.
Asayansi amaganiza kuti mawonekedwe amtundu wa nyamalikiti ndi zakudya, zomwe zimadalira mphukira zazing'ono, masamba ndi masamba amitengo. Mitengoyi ndi yayitali. Chakudya chotere chimakupatsani mwayi wokhala m'malo otentha, pomwe pali nyama zambiri zomwe zimadya udzu, ndipo nthawi yotentha, savanna yatenthedwa kwathunthu. Chifukwa chake akupezeka kuti zinthu zazing'onoting'ono zili bwino.
Acacia ndi chakudya chomwe amakonda kwambiri.... Nyamayo imagwirira nthambi ndi lilime lake ndikuyikoka kukamwa kwake, ndikudula masamba ndi maluwa. Kapangidwe ka lilime komanso milomo ndi koti kathabwa sangathe kuwawononga pamtsempha wa mthethe. Njira yodyetsera imamutengera maola sikisitini kapena kupitilira apo patsiku, ndipo kuchuluka kwa chakudya mpaka makilogalamu 30. Thundu amagona ola limodzi lokha.
Khosi lalitali lilinso vuto. Mwachitsanzo, kuti angomwa madzi, nyamalitsi amatambasula miyendo yake ndikugwada. Malowa ali pachiwopsezo chachikulu ndipo nyamalayi nthawi ngati imeneyi amatha kukhala nyama yolusa. Mng'oma akhoza kukhala wopanda madzi kwa sabata lathunthu, kuthetsa ludzu lake ndi madzi omwe ali m'masamba achichepere. Koma akamwa, ndiye imamwa madzi okwanira 38 malita.
Kuyambira nthawi ya Darwin, akukhulupirira kuti khosi la nyamalayi lidakula kukula chifukwa cha chisinthiko, kuti akadyamsonga m'mbuyomu analibe khosi labwino chonchi. Malinga ndi nthano, nthawi yachilala, nyama zokhala ndi khosi lalitali zimapulumuka, ndipo amatengera izi kwa ana awo. Darwin adati chinyama chilichonse chamiyendo inayi chitha kukhala thonje. Mawu omveka bwino mkati mwa chiphunzitso cha chisinthiko. Koma umboni wa zokwiriridwa pansi zakale ukufunika kutsimikizira izi.
Asayansi ndi ofufuza ayenera kupeza mitundu yosiyanasiyana yazosintha. Komabe, zotsalira zakale za makolo achimphamba masiku ano sizosiyana kwambiri ndi zomwe zikuchitika masiku ano. Ndipo mawonekedwe osinthira kuyambira khosi lalifupi mpaka lalitali sanapezeke pano.
