Ua like ka lewa ma Titan me ka lewa ma ka Honua
Ua piha ka lewa o ka honua i nā hydrocarbons, ka hapa nui o ka methane, ma kahi o ka nitrogen a me ka oxygen. Wahi a ka poʻe ʻepekema mai ke Kulanui ʻEnelani ma Newcastle, hiki i ka Honua ke nānā aku i kahi mea nānā ma waho hypothetical e like me ke ʻano o Titan i kēia lā, ʻo ia hoʻi. ʻeleʻele ʻeleʻele.
Ua hoʻomaka kēia e hoʻololi ma kahi o 2,4 biliona makahiki i hala ma muli o ka hopena o photosynthesis i loko o nā microorganism e ulu ana ma ka Honua. ʻO ia ka manawa i hoʻomaka ai ka hōʻiliʻili o ka huahana o photosynthesis, oxygen, i loko o ko mākou lewa. Ua wehewehe nā kānaka ʻepekema Pelekane i nā hanana i hana ʻia ma laila he "oxygenation nui". Ua hoʻomau kēia ma kahi o 150 miliona mau makahiki, ma hope o ka nalo ʻana o ka noe methane a hoʻomaka ka honua e like me kā mākou i ʻike ai i kēia manawa.
Hōʻike ka poʻe ʻepekema i kēia mau hanana ma muli o ka nānā ʻana i nā sediment moana ma waho o ke kapakai o ʻApelika Hema. Akā naʻe, ʻaʻole hiki iā lākou ke wehewehe i ke kumu i hoʻomaka ai ia manawa. ka saturation ikaika o ka Honua me ka oxygenʻoiai aia nā microbes photosynthetic ma ko kākou honua he mau haneli miliona mau makahiki aku nei.
