Esikhathini esingengakanani esidlule, ososayensi bezinto eziphilayo baseNingizimu Afrika bathola ukuthi endaweni yabo yemvelo, izindlovu zilala ngezindlela ezihlukile: zombili amanga nokuma. Nsuku zonke, i-colossus ingena ebuthongweni bamahora amabili ngaphandle kokushintsha ukuma komzimba wayo, futhi kanye kuphela ezinsukwini ezintathu ziyazivumela ukuba zilale phansi, zingene esigabeni sokulala se-REM.
Ukuqagela
Kunezinguqulo eziningana zokuthi kungani izindlovu zivame ukukhetha ukuzinikela ezandleni zikaMorpheus ngenkathi zimile.
Okokuqala. Izilwane azilali phansi, zivikela isikhumba esincanyana phakathi kwezinzwani ekungeneleleni kwamagundane amancane, nezindlebe nesiqu kusuka ekungeneni kwezihuquzelayo ezinobuthi kanye namagundane afanayo kuzo. Le nguqulo ayinakubekezeleka ngenxa yeqiniso elilula: izindlovu (ezinesikhumba esibucayi) zilale phansi phansi ngokuthula.
Okwesibili. Imidondoshiya enesisindo samathani amaningana ayivamile ukulala phansi, ngoba esimweni esithandekayo banomfutho oqinile wezitho zabo zangaphakathi. Le hypothesis nayo ayimele ekugxekweni: ngisho nezindlovu ezindala zinohlaka lwemisipha oluqinile ngokwanele oluvikela izitho zangaphakathi.
Okwesithathu. Lokhu kuma kusiza isisindo sokusinda esisindayo ukuba sisheshe sithathe isinyathelo sokuzivikela lapho sihlaselwa ngokungazelelwe yizidlakela ezilambile. Le ncazelo ifana neqiniso: ngokuhlaselwa okungalindelekile, indlovu ngeke nje ikwazi ukuma ngezinyawo zayo futhi izofa.
Okwesine. Imemori yofuzo yenza izindlovu zilele zimile - le yindlela okhokho bayo abakude, ama-mammoth, abalala ngayo ngezinyawo. Ngalokhu, bavikela imizimba yabo ku-hypothermia engaba khona: ngisho noboya obuningi abuzange busindise izilwane ezincelisayo zasendulo emakhazeni amakhulu. Kulezi zinsuku, uhlobo lofuzo alunakuphikiswa noma luqinisekiswe.
Zilala kanjani izindlovu
Akukho nokuvumelana ngalolu daba. Ngokuvamile kwamukelwa ukuthi izindlovu zase-Afrika naseNdiya zikhetha ukuma okuhlukile kokulala.
Izici zezinhlobo
Abantu base-Afrika bayolala bemi, bancike eceleni kwesiqu somuthi noma bayihlanganise ngesiqu. Kunenkolelo engenabufakazi yokuthi izindlovu zase-Afrika azizi phansi ngenxa yokwesaba ukushisa emhlabathini oshisayo. Esimweni sezulu esishisayo ngokulingene, izilwane ziyazivumela ukuthi zilale ngezisu, imilenze igobile nesiqu sigobile. Kukholakala ukuthi abesilisa bavame ukulala bemi, izintombi namazinyane abo bavame ukuphumula belele.
Kuthiwa izindlovu zaseNdiya maningi amathuba okuba zilale zibambe ongezansi, zigobise izitho zazo zangemuva bese zilalisa amakhanda azo ngaphambili enwetshiwe. Ojahidada nentsha bayathanda ukozela ngasohlangothini lwabo, kanti izilwane ezindala mancane amathuba okuthi zilale esiswini / ohlangothini, zikhetha ukulala lapho zimile.
Amaqhinga endlovu
Ukuhlala ngezinyawo, lezi zilwane ziyalala, zibeka iziqu zazo / iziqu zazo emagatsheni awugqinsi, futhi zibeka nezindondo ezisindayo esidulini somuhlwa noma enqwabeni ephakeme yamatshe. Uma ubuthongo budlula lapho ulele, kungcono ukuthi ube nokuxhaswa okuqinile eduze okuzosiza indlovu ukuthi ikhuphuke phansi.
Kuyathakazelisa! Kukhona umbono wokuthi ubuthongo obuzolile bomhlambi buhlinzekwa ngabalindi (1-2 izindlovu), abagcina ngokucophelela indawo ezungezile, ukuze bavuse izihlobo ngesikhathi engozini encane.
Into enzima kakhulu ukulala yizinduna esezikhulile, okumele zisekele ikhanda lazo elikhulu, zithwelwe ngamazinyo aqinile, izinsuku eziningi. Ukugcina ibhalansi, amaduna amadala agona umuthi noma alala ngohlangothi lwawo, njengamazinyane. Izindlovu ezisencane ezingakasindi zisalala phansi kalula futhi zisheshe zisukume.
Izingane zizungezwe izindlovu ezindala, zivikela izingane ekuhlaselweni ngobuqili bezilwane ezizingelayo. Ukulala isikhashana kuphazanyiswa ukuvuswa njalo: abantu abadala bahogela iphunga elingaphandle futhi balalele imisindo ethusayo.
Amaqiniso
INyuvesi yaseWitwatersrand yenze ucwaningo ngokulala kwezindlovu. Vele, le nqubo isivele ibonwe ema-zoo, okuqinisekisa ukuthi izindlovu zilala amahora ama-4. Kepha ukulala ekuthunjweni kuhlala isikhathi eside kunasendle, ngakho-ke ososayensi bezinto eziphilayo baseNingizimu Afrika banqume ukukala isikhathi sokulala ngokuya ngomsebenzi wesitho sendlovu esihamba phambili kunazo zonke, isiqu.
Izilwane zakhishelwa ku-savannah, ifakwe ama-gyroscopes (akhombisa ukuthi indlovu yalala ikuphi), kanye nabemukeli be-GPS ababeqopha ukuhamba komhlambi. Izazi ze-Zoologists zithole ukuthi izikhonzi zabo zilele isikhathi esingeqile emahoreni ama-2, futhi njengomthetho - ngenkathi zimile. Izindlovu zilala phansi njalo ezinsukwini ezi-3-4, zilale isikhathi esingaphansi kwehora. Ososayensi banesiqiniseko sokuthi kwakungaleli hora lapho izilwane zangena khona ebuthongweni be-REM, lapho kwakhiwa inkumbulo yesikhathi eside futhi kuphupha amaphupho.
Kwavela nokuthi iziqhwaga zidinga ukuthula nokuthula: izidlakela, abantu noma izilwane ezincelisayo ezidla inyama ezizulazulayo zingaba ngumthombo wokungezwani.
Kuyathakazelisa! Ngokuzwa ukuba khona komakhelwane abanomsindo noma abayingozi, umhlambi ushiya indawo yawo oyikhethile futhi ungahamba ibanga elingamakhilomitha angama-30 uyofuna indawo ethulile yokulala kwabo.
Kwacaca ukuthi ukuvuka nokulala ezindlovu akuhlobene ngokuphelele nesikhathi sosuku. Izilwane bezingaholwa kangako ngokushona kwelanga nangokuphuma kwelanga njengokushisa nomswakama obekulungele zona: imvamisa izindlovu zilala ekuseni kakhulu, lize liphume ilanga.
Isiphetho: endalweni, izindlovu zilala uhhafu njengasekuthunjweni, futhi ziphindwe kane kunabantu.
