4600 millions d\u2019ann\u00e9es jusqu\u2019\u00e0 aujourd\u2019hui

Selon tout ce que nous savons, la Terre s\u2019est form\u00e9e il y a 4,6 milliards d\u2019ann\u00e9es, avec le Soleil et les autres plan\u00e8tes de notre syst\u00e8me solaire.
\nEn ce temps-l\u00e0, l\u2019univers lui-m\u00eame a d\u00e9j\u00e0 9,2 milliards d\u2019an\u00adn\u00e9es. Si l\u2019on devait marquer un endroit qui repr\u00e9\u00adsente le d\u00e9but de l\u2019es\u00adpace et du temps, ce serait \u00e0 envi\u00adron 2,2 km avant ce panneau.
\nQuelque part sur le chemin jusqu\u2019au prochain tableau d\u00e9bute l\u2019\u00e9vo\u00adlu\u00adtion chimique. Cela signi\u00adfie la forma\u00adtion abio\u00adtique de mol\u00e9\u00adcules plus grosses \u00e0 partir des compo\u00adsants de la soupe primor\u00addiale. A la prochaine station, elle \u201cembouche\u201d dans l\u2019\u00e9volution biolo\u00adgique. C\u2019est l\u00e0, \u00e0 une distance de seule\u00adment 122 m\u00e8tres, que commence le d\u00e9ve\u00adlop\u00adpe\u00adment de la vie \u2013 l\u2019\u00e9volution.
\nDonc, d\u00e9j\u00e0 500 millions d\u2019ann\u00e9es apr\u00e8s la forma\u00adtion de notre systeme solaire, les premi\u00e8res traces de vie sur Terre sont d\u00e9tec\u00adtables. Cela sugg\u00e8re que, dans des condi\u00adtions appro\u00adpri\u00e9es, la forma\u00adtion de la vie n\u2019est pas aussi impro\u00adbable qu\u201d on l\u2019avait long\u00adtemps suppos\u00e9.<\/p>\n

La Terre est tr\u00e8s chaude. Apr\u00e8s l\u2019apai\u00adse\u00adment de bombar\u00adde\u00adments de m\u00e9t\u00e9o\u00adrites, elle se refroi\u00addit \u00e0 tel point qu\u2019une mince cro\u00fbte se forme. Volca\u00adnisme et \u00e9vapo\u00adra\u00adtion des gaz provoquent la forma\u00adtion d\u2019une premi\u00e8re atmo\u00adsph\u00e8re, toujours sans oxyg\u00e8ne. Un peu d\u2019eau humide condense de la vapeur.<\/p>\n","protected":false},"excerpt":{"rendered":"
