ʻO ka hadic eon, i ʻike ʻia ʻo hadean a hadean, ʻo ia ka wā kahiko loa ma ka Honua. Hoʻomaopopo mai ka hoʻokumu ʻana o ka Honua ma kahi o 4.550 biliona mau makahiki i hala aku nei a i kahi o 4.000 / 3.800 biliona mau makahiki i hala. ʻAʻole kū pololei ka wā, akā he manawa pili ʻole ia no ka mea ʻaʻole i hoʻonohonoho a ʻike ʻia kēia mau palena. ʻO ke komisina e mālama ana i ka hoʻokumu ʻana i nā palena a me ke aʻo ʻana i ka stratigraphy, geology a me geochronology ma ka pae honua ka Komisina International ma Stratigraphy.

Supereon ʻEonā Miliona o nā makahiki
Precambrian Proterozoic 2.500 a 540
Precambrian Kahiko 3.800 a 2.500
Precambrian ʻO Hadic 4.550 a i ka 3.800

Kēia wā, no laila ʻike ʻole ʻia, aia i ka manawa like kahi hoʻomaka o ko mākou honua. Ua manaʻo ʻia e hoʻokumu ana ka ʻōnaehana o ka lā i waenakonu o kahi ao nui o ke kinoea a me ka lepo. ʻO ka haic aeon ʻo ia nō ke au Nui ka hoʻololi o ka honua. Ma muli o ka nui o nā luaʻi pele, a ʻo ka manawa hoʻi i loaʻa ai ka Honua a me nā paneta o loko o ka ʻōnaehana nui i nā hopena nui mai nā asteroids nui. ʻO kekahi o lākou ka Moon kūʻē i ka Honua (a mākou i kamaʻilio ai i kēia manawa, i curiosities o ka Honua, kuhikuhi 5).

Nā hōʻike o ka Hadic Aeon

Kāʻei supracortical Isua

Kāʻei Supracortical mai Isua. ʻO ka mōʻī microbial kahiko loa o nā mea āpau i ʻike ʻia, mai ka makahiki 3.480 biliona

Ke ʻie nā pōhaku kahiko loa, e hele ana mākou i Greenland, Kanada a me Australia. ʻO lākou he 4.400 biliona mau makahiki. ʻO nā pōhaku Hadic, i loaʻa i loko o nā makahiki he XNUMX i hala i hala, he mau minela aniani zircon. ʻOiai ʻo lākou nā minelala mua loa i ʻike ʻia, a hūnā lākou i ka waiho hohonu ʻana ma lalo o nā sediment ma ke komohana o Kanada a me ka moku ʻo Jack Hills ma ke komohana o Australia, ʻaʻole pili lākou i nā papa pōhaku.

ʻO nā papa pōhaku kahiko loa ʻo ia ka lā i ʻike ʻia ma mua ʻO 3.800 miliona mau makahiki. ʻO ka mea kahiko loa i Greenland, ʻike ʻia ʻo ka "Kāʻei Supracortical o Isua". Hoʻololi iki ʻia lākou e nā lua pele i komo i loko o nā pōhaku ma hope o ka waiho ʻia ʻana. I loko o ka puke "Conceptions e pili ana i ke kumu o ke ola" na Diego Sebastián González lāua ʻo Maricel Ciela Gutiérrez loaʻa iā mākou, me ka ʻikepili loea, akā he hoʻokalakupua loa ia, kekahi o nā nīnau a mākou e nīnau mau ai iā mākou iho. Ma hea e hoʻomaka ai ke ola? A ma laila lākou, nā hōʻike mua mua, i ke kāʻei supracortical o Isua, i ka Hadic Aeon.

Ke kumu o ke ola ma ka honua

kahua honua honua

Aia nā sediment Greenland i nā hao hao i hoʻopaʻa ʻia. I ka manawa mua ua manaʻo ʻia he ʻāpana kalapona paha kā lākou, kahi e hōʻike ai aia nō paha ka hoʻomaka mua ʻana o nā molekiola ponoʻī. I kēia manawa aia he hōʻike mua e pili ana ke ola mai ka kāʻei supracortical Isua, mai West Greenland, a mai nā mokupuni ʻo Akilia, mai kahi like. Pono e hoʻomanaʻo ʻia, ʻoiai ʻo ka ʻike ʻepekema i loaʻa i kēlā wahi, ʻaʻole hiki iā mākou ke kuhikuhi i ka wā i hala. Hoʻomanaʻo i ka Honua, ʻaʻole wale nō i hoʻokumu ʻia, akā ma hope o ke ʻano o ka hoʻokumu ʻana, hoʻomau ka neʻe o nā papa ʻāina.

ʻO nā papa pōhaku e haku iā ia i loaʻa i ka -5,5 o Carbon (C) 13, C13. ʻO kēia ma muli o ke kaiaola biotic e makemake i ka isotope C12 māmā. ʻO ka C13 i ka biomass, hōʻike i nā concentrations o -20 a me -30, ʻoi aku ka haʻahaʻa ma mua o nā paʻa i loaʻa i nā hana pōhaku. Mai kēia mau loea kuhi ʻia hiki i ke ola ma kā mākou honua ke hoʻomaka maoli i 3.850 miliona i hala mau makahiki, i ka hopena o ka Hadic eon.

Ka hoʻomaka ʻana o ka wai

Manaʻo ʻia aia ma waena o nā hunaahi i hoʻokumu ʻia ai ka Honua, aia paha i kahi nui o ka wai. ʻAʻole pono e pio kēia mau mole i ka umekaumaha, a neʻe aku mai ke kikowaena, ua mau lākou ma ka ʻili. Ma hope o ka hōʻea ʻana o ka Honua i 40% o kāna hoʻokumu ʻanaʻO kēia mau mole wai, a me nā mea ʻāwīwī ʻē aʻe, pono e ʻike ʻia ma ka ʻili, i nā nui he nui ʻē. ʻO ka nele o nā kinoea hanohano he nui e pakele ai ke kū nei, e like me ka helium a me ka hydrogen. Ua alakaʻi kēia i ka manaʻoio i mea e hiki mai kahi catastrophic i ka lewa mua. Ma waena o ke kuhiakau, he manaʻo ko mākou no Theia, a mākou i kūkākūkā ai i kēlā 'atikala hope (helu 5), wehewehe no ke aha mai ka Moon e like me.

ʻO kāna hopena catalytic i ke ola

pele magma a me ka wai

ʻO nā manaʻo e pili ana i ka hana ʻana o ka wai ma ke ʻano he catalyst i hāʻawi ʻia e Lazcano lāua ʻo Miller i ka makahiki 1994. ʻO ka loulou, i wehewehe ʻia, no ka holo ʻana o ka wai ma o nā puka kai submarine moana. He 10 miliona mau makahiki ka lōʻihi o ka hoʻopulapula ʻana, akā hiki ke luku ʻia kekahi hui kūlohelohe i nā mahana ma luna o 300ºC. No laila, ma hope o ka hōʻoluʻolu mālie, he meaola kahiko Heterotroph DNA-protein me kahi genome 100 kilobase, ma kahi o 7 miliona mau makahiki e hoʻololi ai ia i kahi genome o cyanobacteria me nā genes 7.000.

A aia kekahi mea a mākou i haʻi ʻole aku ai, e loaʻa paha kahi pane i kekahi lā. I kēia lā nō ka nīnau nui e pane. ʻO ke ola, e like me ka ʻike, hiki wale ke ola i ke ʻano o ke kalapona a i ʻole ke silika. Ma kā mākou Honua, noho ʻo ia e like me ke kalapona, ʻaʻole ka silikone, ʻo wai ka mea ʻike inā ma kahi ʻē aʻe e hana ai. Akā ʻo ka nīnau maoli, pehea e ulu ai ke ola inā ʻaʻohe pono ka likelike o kēlā hanana?

ʻAʻole hiki ke ʻike ʻia inā mākou e noʻonoʻo e pili ana iā ia i ka pō, nānā mākou i nā hōkū. Ke hoʻokuʻu nei iā mākou iho e nā manaʻo nui e kū aʻe.

Ma hope o ka Hadic eon, ka Archaic eon. Inā hoihoi ʻoe i ka ʻike pehea ka hoʻomau ʻana, kaomi ma aneʻi.


Hoʻopili ka ʻike o ka ʻatikala i kā mākou kumumanaʻo o ka hoʻoponopono hoʻoponopono. E hōʻike i kahi kaomi hemahema ʻaneʻi.

E lilo i mea mua e wehewehe

E waiho i kāu manaʻo

Kāu leka uila aae? E,ʻaʻole e paʻiʻia.
