Zinsinsi za dziko - nthawi Mathanthwe

Malinga ndi sayansi boma zamoyo padziko lino pafupifupi biliyoni zaka zitatu zapitazo mu mawonekedwe a zamoyo yosavuta - akutali ndodo tosaoneka ndi maso, nyumba filamentary, ozungulira ndi polygonal tating'ono algae. Tizilombo timeneti akhoza unalipo mu madzi ndi kokha mu nyengo ofunda.

Ambiri, kuti anapulumuka mafupawa ochepa kwambiri kuchokera nthawi Precambrian. Evolution akuoneka ndayima kaye kuyambira chiyambi cha moyo zaka biliyoni atatu, kusintha ndi kutsiriza mitundu yekha alipo wa algae ndi tizilombo tosaoneka.

Komabe, zaka miliyoni 580 zapitazo, pa inasintha mbiri ya kusanduka - nthawi Mathanthwe. Kutalika kwake ndi mu moyo wa Lapansi ndi zazing'ono - zaka 80 miliyoni. Zinali ndiye kuti mwadzidzidzi ndi pafupifupi imodzi panali zosiyanasiyana chodabwitsa mitundu nyama zonse zopanda mafupa. Chofunika - zamoyo mu nthawi yochepa anatha kukhala olimba Mbali yokhala ngati mafupa.

Angapo kwachilengedwenso mitundu ya Mathanthwe anali kuloŵedwa m'malo a mitundu yonse ya moyo wamasiku ano, kuphatikizapo anthu. Ili ndi nthawi yatsoka ndi kuchuluka kwake ndi mitundu ya zinthu zamoyo monga kuphulika Mathanthwe.

Land pa nthawi anali pustnynyu mtheradi, moyo wonse anaikira kokha mmadzi. Mayiko a padziko lapansi anali ndi malo zosiyana Mwachitsanzo, pa malo a Greenland ndi North America ndi South America Lavrentsov kum'mwera anali kumtunda ku Brazil. Arabia, Africa ndi Madagascar anali ogwirizana African Africa ili kumpoto kwa Chile Russian, wosiyana ndi Khwalala ya kwambiri Siberia ndi kumtunda Chinese. Kum'mwera, panali chimphona Australia Chile, chomwe pambuyo odukaduka ku India, Australia ndi chiwerengero cha zilumba.

Mu nthawi Mathanthwe anatuluka ena phiri wamakono: Kumpoto Appalachian mapiri, Sayan Ridge Mapiri Chingiztau (Kazakhstan).

Mu madzi, mofulumira maluwa moyo: popeza zitakhazikika ndipo trilobites, radiolarians, thonje, brachiopods. Anaonekera archeocyathids - nyama multicellular, umene ndi mtanda pakati pa miyala yamtengo wapatali ndi thonje. Iwo massively yomatidwa pansi pa matupi madzi, kupanga mtundu wa moti matanthwe. Pofika kumapeto kwa Mathanthwe, iwo anakhala zinatha.

Panthawi imeneyi, makamaka trilobites asangalala - arthropods wosazindikira ngati woodlice ano. Iwo anali lathyathyathya yooneka ngati mbale imayamba thupi ndi zida chitinous, ogaŵikana zigawo 45-50 ndi kuchuluka kwa miyendo.

Chakumapeto kwa Mathanthwe munali woyamba inakhala oti muli nazo zida, prototypes nsomba.

Motero, popanda njira iliyonse Transitional ndi mitundu wapakatikati kumangako mabakiteriya mogwirizana mu dziko mwadzidzidzi anapanga ambiri nyama zonse zopanda mafupa ndi peresenti mitundu, prototypes mitundu ano. Nthawi Mathanthwe ndi ovuta kuwamvetsa zamoyo zinachita kulumpha mu mbiri ya dziko.

Nthawi zambiri ofufuza zimachitika izi chosintha chochitika yovuta kudzikundikira mpweya mu mlengalenga m'nyanja, komanso kukula salt ankatenthetsa wa chotchedwa sushi ndi kukula woipa kashiamu ndi magnesium mu madzi. The mankhwala zikuchokera madzi zasintha kwambiri kuti majeremusi okhala kumeneko, ali nazo zochuluka za mwayi kusintha ndi mapangidwe mitundu.

Ngakhale amati pafupifupi nthawi ino, Earth wapanga chiwembu mwadzidzidzi pafupifupi 90 madigiri, nchifukwa chake kunali kosangalatsa chidwi za m'maiko onse, mosinthana tectonic ndi mapangidwe thandizo la makono a padziko lapansi. Iwo nawonso anakopeka mapangidwe mitundu yatsopano ndipo zimasintha kupulumuka.

The nyengo kusanduka Lapansi anakumana kwambiri masoka Choncho, pafupifupi imodzi ndi wopanda zinyamazi kupatulapo mbisoweka zaka 65 miliyoni zapitazo. Ndipo m'nyengo Permian mu yochepa nthawi yomweyo anayamba zinatha pafupifupi 95% ya moyo m'madzi - Zaka miliyoni 245 zapitazo.

Koma mwa zinsinsi zonsezi kokha nthawi Mathanthwe losiyana kulenga yake, osati kuwonongedwa kwa mitundu. Otsutsa za njira zamoyo zinachita kuona mu chithunzi cha Mathanthwe kuphulika chitsimikiziro cha chiyambi cha Mulungu mitundu yamakono ya moyo, kuphatikizapo anthu.
