I-Agropolitan Theory: Ukwakha Umqondo Wentuthuko Eqhubekayo Ezindaweni Zasemakhaya Isingeniso Intuthuko yasemakhaya ivame ukuba yinselele enkulu emazweni amaningi asathuthuka, okuhlanganisa ne-Indonesia. Omunye umqondo oye wavela ukuze ubhekane nale nselele yi-Agropolitan Theory. Owethulwe ngasekupheleni kwekhulu lama-20, lo mqondo ugxile ekuthuthukisweni kwasemakhaya ngokuhlanganisa umkhakha wezolimo nezici zezomnotho, ezenhlalo nezamasiko. … Funda kabanzi
Imibuzo Eyisibonelo Exoxa Ngombono Wokuziphendukela Kwemvelo Wangemva KukaDarwin. Ukuziphendukela kwemvelo kuwumqondo oyisisekelo ku-biology ochaza indlela izinto eziphilayo ezishintsha ngayo ngokuhamba kwesikhathi ngokukhetha kwemvelo nezinye izindlela. Ngemva kokuba uCharles Darwin ethule umbono wokuziphendukela kwemvelo ngokukhetha kwemvelo ngekhulu le-19, ososayensi abaningi baqhubeka nocwaningo lokwandisa nokubuyekeza umbono. Umbono wokuziphendukela kwemvelo wangemva kukaDarwin uhlanganisa imibono… Funda kabanzi
Ithiyori Yendawo Ephakathi Isingeniso Ithiyori Yendawo Ephakathi ingumqondo wezwe ohlobene nokuthuthukiswa nokusatshalaliswa kwamadolobha kanye nezindawo zokuhlala zabantu. Lo mbono wethulwa okokuqala nguWalter Christaller, isazi sejografi saseJalimane, ngo-1933 encwadini yakhe ethi "Die Zentralen Orte in Süddeutschland" (Izindawo Eziphakathi ZaseNingizimu Jalimane). Lo mbono uhlose ukuchaza ukusatshalaliswa kwamadolobha… Funda kabanzi
Umbono Wendawo Ofanele: Ukuqonda Indawo Engcono Kakhulu Yebhizinisi Indawo ingenye yezici ezibaluleke kakhulu zokuqhuba ibhizinisi. Akubalulekile nje kuphela ezitolo ezidayisa izinto zokwakha, kodwa futhi kusebenza emahhovisi, ezindaweni zokugcina impahla, nakwezinye izinhlobo ezahlukene zamabhizinisi. Ukukhetha indawo okungekuhle kungaholela ekwehleni kwenzuzo kanye nobunzima ekusebenzeni kwansuku zonke. Yilapho ukuqonda... Funda kabanzi
Imibuzo Eyisibonelo Exoxa Ngobufakazi Bama-Molecular kanye Nokufana Kwe-DNA Ku-biology, ubufakazi bama-molecule kanye nokufana kwe-DNA kudlala indima ebalulekile ekuqondeni ukuziphendukela kwemvelo, ubudlelwano phakathi kwezinhlobo, kanye nezindlela zofuzo ezisekela ukuphila. Ngokuthuthuka kwezobuchwepheshe, singaphenya ngesakhiwo se-DNA nama-molecule ukuze sithole ukuqonda okujulile ngendlela impilo esebenza ngayo. Lesi sihloko sizoxoxa… Funda kabanzi
Imibuzo Nengxoxo Yesibonelo Sokushelela Kwezakhi Zofuzo Isingeniso Ukushelela kwezakhi zofuzo kuyindlela yokuziphendukela kwemvelo ebhekisela ezinguqukweni ezingahleliwe kuma-allele frequency ngaphakathi kwabantu. Lesi simo ngokuvamile sinemiphumela enamandla kubantu abancane lapho izehlakalo ezingahleliwe zingathinta kakhulu isakhiwo sezakhi zofuzo sabantu. Lesi sihloko… Funda kabanzi
Ithiyori Yakudala: Ithiyori Yokuqashisa Umhlaba Ithiyori yakudala yokuqashisa umhlaba ingumqondo obalulekile kwezomnotho owavela ngekhulu le-18 nele-19, lapho izazi zezomnotho zakudala ezifana no-Adam Smith, uDavid Ricardo, noThomas Malthus baqala ukuhlola ukuguquguquka kokukhiqiza nokusatshalaliswa emnothweni. Le thiyori igxile endleleni umhlaba, okungenye ye… Funda kabanzi
Isihloko: Imibuzo Eyisibonelo kanye Nengxoxo Ngombono KaDarwin Wokuziphendukela Kwemvelo Umbono KaCharles Darwin Wokuziphendukela Kwemvelo ungomunye wemisebenzi enethonya elikhulu emlandweni wesayensi, oshintsha indlela esibheka ngayo ukuphila eMhlabeni. Yanyatheliswa okokuqala ngo-1859 ngaphansi kwesihloko esithi "On the Origin of Species," lo mbono uchaza ukuthi izinhlobo zishintsha kanjani ngokuhamba kwesikhathi ngendlela yokukhetha...

Ithiyori Yendawo: Ukuhlola Amandla Okubekwa kanye Nomthelela Wawo Emnothweni Isingeniso Ithiyori yendawo iyigatsha elibalulekile lezomnotho kanye nejografi eligxile ekuhlaziyweni kokukhethwa kwendawo ngabantu noma izinkampani ukuze kwandiswe inzuzo kanye nokusebenza kahle. Lokhu kukhethwa kwendawo kusekelwe ezicini ezahlukahlukene, okuhlanganisa izindleko zokukhiqiza, ukufinyelela emakethe, ezokuthutha, abasebenzi, kanye nobuchwepheshe. … Funda kabanzi
Ithiyori Yokukhula Kwesigxobo: Ukuqonda Amandla Nemiphumela Yayo Isingeniso Ithiyori Yokukhula Kwesigxobo ingumqondo kwezomnotho wentuthuko owethulwa yisazi sezomnotho saseFrance uFrançois Perroux ngo-1955. Lo mbono uqokomisa ukusatshalaliswa okungalingani kwentuthuko yezomnotho kuzo zonke izifunda futhi ufuna ukuqonda ukuthi izigxobo zokukhula zingayiqhuba kanjani intuthuko yezomnotho iyonke.
