4100 millions d\u2019ann\u00e9es jusqu\u2019\u00e0 aujourd\u2019hui

La terre est encore tr\u00e8s jeune, quand l\u2019\u00e9volution chimique se trans\u00adforme en \u00e9volu\u00adtion biolo\u00adgique. C\u2019est le d\u00e9but du d\u00e9ve\u00adlop\u00adpe\u00adment de la vie. Des traces des premi\u00e8res formes de vie, des fossiles tubu\u00adlaires micro\u00adsco\u00adpiques, peuvent encore \u00eatre trou\u00adv\u00e9es dans certaines roches aujourd\u2019hui.<\/p>\n

La vie d\u00e9bute dans l\u2019eau. Des cellules primor\u00addiales commencent \u00e0 se multi\u00adplier. Elles passent leur infor\u00adma\u00adtion g\u00e9n\u00e9\u00adtique \u00e0 leurs descen\u00addants. Au cours de ce proces\u00adsus, le mat\u00e9\u00adriel g\u00e9n\u00e9\u00adtique change et est soumis \u00e0 la s\u00e9lection.<\/p>\n

Pendant la migra\u00adtion d\u2019une station \u00e0 l\u2019autre, essayez de vous rendre compte de la longueur inima\u00adgi\u00adnable de 4100 millions d\u2019ann\u00e9es.<\/p>\n

L\u2019atmosph\u00e8re premi\u00e8re est compo\u00ads\u00e9e de 80% de vapeur d\u2019eau, 10% de dioxide de carbone et dioxide de soufre (sulfure), nitro\u00adg\u00e8ne et autres mol\u00e9\u00adcules. Gr\u00e2ce au refroi\u00addis\u00adse\u00adment de la terre, la vapeur d\u2019eau condense. La pluie inces\u00adsante et la forma\u00adtion des oc\u00e9ans en sont la cons\u00e9quence.<\/p>\n","protected":false},"excerpt":{"rendered":"
