Umugqa wesikhathi womlando womuntu: Izehlakalo ezibalulekile ezalolonga umhlaba wethu

Kuqala ngokuvela kwabantu bokuqala futhi kuqhubeke ngempucuko ehlukahlukene, imiphakathi, kanye nezigigaba ezibalulekile njengokusungulwa kokubhala, ukukhuphuka nokuwa kwemibuso, intuthuko yesayensi, kanye nokunyakaza okubalulekile kwamasiko nezepolitiki.
Umlando omfushane Womhlaba: Isikali sesikhathi sokuma kwezwe - ama-eons, ama-eras, izikhathi, ama-epoch neminyaka
Umlando woMhlaba uyinganekwane ethokozisayo yokuguquka njalo nokuziphendukela kwemvelo. Eminyakeni eyizigidigidi, iplanethi iye yaba nezinguquko ezimangalisayo, ezakheka amandla okwakheka komhlaba kanye nokuvela kokuphila. Ukuze baqonde lo mlando, ososayensi benze uhlaka olwaziwa ngokuthi isikali sesikhathi sokuma kwezwe.
Isibankwa sasolwandle esilingana nomuntu sasendulo sibhala kabusha umlando wezilwane ezihuquzelayo zasolwandle zakuqala ezihlomile
Izinhlobo ezisanda kutholwa, i-Prosaurosphargis yingzishanensis, zakhula zaba ngamafidi angu-5 ubude futhi zazimbozwe amazenga amathambo okuthiwa ama-osteoderms.
Ingabe ama-octopus "angabafokazi" avela emkhathini? Uyini umsuka walesi sidalwa esiyimpicabadala?
Sekuyisikhathi eside ama-octopus eheha umcabango wethu ngemvelo yawo engaqondakali, ubuhlakani obumangalisayo, kanye namakhono omhlaba. Kodwa kuthiwani uma kunokuningi kulezi zidalwa eziyimpicabadala kunalokho esingakubona?
Yini ebangele ukushabalala kwenqwaba ye-5 emlandweni womhlaba?
Lezi zici ezinhlanu zokuqothulwa, ezaziwa nangokuthi "i-Big Five," ziye zashintsha inkambo yokuziphendukela kwemvelo futhi zashintsha ngokuphawulekayo ukuhlukahluka kwempilo eMhlabeni. Kodwa yiziphi izizathu ezibangela lezi zenzakalo eziyinhlekelele?
Okhokho abadala kunabo bonke kungenzeka ukuthi bavela eminyakeni eyizigidi eziyisishiyagalolunye edlule eTurkey

Izinsalela zamaShayina ezineminyaka engu-250-million zembula izilwane ezihuquzelayo zisebenzisa okokuhlunga okufana nemikhomo.
Ukutholwa kwamuva nje kwensalela yaseShayina kubonisa ukuthi iqembu lezilwane ezihuquzelayo lalinohlelo lokuphakela okomkhomo eminyakeni eyizigidi ezingu-250 edlule.
