Era Proterozoic: te ara tataramoa o te kukuwhatanga o te whenua

era Proterozoic, i roa e pā ana ki e rua piriona tau, kua kairau a he wāhi nui i roto i te hanganga o te ao e mohio ana tatou i te reira i teie nei. Ko te roa rawa tenei wā arowhenua, ka tango i te reira tata hawhe o te hītori katoa o te ao, i tohua e te maha o ngā tohu, tahuri hoki te whanaketanga o te whenua.

Te reira i era Proterozoic "tuhia" he hua i roto i te tini wai i roto i te wai ōnuku, kia e timata te moana tuatahi ki te hanumi ki te moana kotahi i runga i te tauine planetary, tae rawa te taumata o nei nga tupuke moana runga. Tenei tectonics rohe geochemical tuatahi tohua e te hua koi i roto i te tohu o te Hydration o te uho lithosphere moana (e tika ana ki ngā rohe waiwai nui Rift papatipu nui moana te wai tote). roa tenei tukanga hoki e pā ana ki te ono rau miriona tau. A takaro reira he wāhi tino hira i roto i te hanganga o muri o te awhina o te papa moana.

I roto i te wahi o te atamira hītori tino tawhito, ka haere mai te Archean, wā Proterozoic. Ko te āhuarangi Ko timata te timatanga o te wā hou ki te huri tino. Ko te mata o te ao ko te wā i roto i Archaean koraha makariri ngā mate, me te whanau ki te glaciations auau, Maumau ofi ki waenganui te Proterozoic nui rerekētanga (i roto i te ahunga o te mahana).

I te wa taua i reira ko tetahi waiwai nui o te hāora i roto i te huru radically kua e puta ke te aronga o te kukuwhatanga o ngā kaiao koiora. Scientists puta tenei e me'a mahu'inga e pā ana ki e rua piriona tau ki muri, kua oti kē i huaina reira "hāora kino." āhuatanga tēnei wā e te nucleation tuatahi rauropi pūtau takohe (no te mea i ranea ki te whakarite i to ratou ora te kukū hāora o te ranunga rangi). Ko reira ka e mate te nuinga o ngā momo i kaiao anaerobic, hoki i te whakamate hāora rāpoi. E, ki te whānuitanga nui, whakaritea te vector o te kukuwhatanga atu.

I roto i tenei āputa pihi nui microorganisms rangitahi me pükohu. Engari tukanga kaha o tata katoa nga toka parataiao i tohua te wā Proterozoic, puta ki te tika (me te kaha rawa) whai wāhitanga o ēnei puka ora.

Eukaryotes, turakina i te scene whanaketanga "ki muri" prokaryotes, rawa, i hanga e, ka ko reira Proterozoic era. Animals, hau breathable, i te ara, i reira i runga i te ao i te wā o mua taua. Te nuinga momo o otaota o te wā Proterozoic Late kua aroaro puka eukaryotic multicellular. Ko te mutunga o tenei wā, kia pai kia huaina "te rau tau o te kakaru," e ka ka kaha i runga i te ao. I te wa ano i tetahi annelids (tupuna o kaiwhao me angawaho).

ko era Proterozoic grandiose wā roanga hītori i roto i i timata ture rorona pūtau eukaryotic. ka anga tahito puka rauropi pūtau me te taiwhenua o te ora ki te kia whakakapia e tino whakaritea mea multicellular. Life iho kua riro he take nui i roto i te kunenga arowhenua. Kua timata kaiao ora ki te tango i te wahi kaha i roto i te huri i te hanganga me te āhua o te kirinuku o te whenua, hei ratou te pūtake o tona paparanga runga - te ao koiora. Haere mai ki te whenua , te ahotakakame, te uara o e kore e taea te amuitahiraa. E te na ke ia te hanganga o te kōhauhau, saturating tona nui nui o te hāora i hanga taea te whanaketanga o teitei kaiao heterotrophic - kararehe teitei.

Ko te kupu, ki te hanga i ngā āhuatanga tino pai mō te haere mai ana ki te ao o ngā teitei o te ora - te tangata nei i ki te huri i te mata o te ao faataahia te mo te iti o tona oraraa (anake 500 mano tau - he tonu i nga paerewa o te arowhenua!) I tua atu āhukahuka. Na, i te wa ano, ka ki te hoatu te ariā o "te ora" me "kunenga" he tikanga hou katoa ...
