Le d\u00e9ve\u00adlop\u00adpe\u00adment des plantes \u00e0 fleurs a proba\u00adble\u00adment commenc\u00e9 il y a envi\u00adron 200 millions d\u2019an\u00adn\u00e9es, lorsque certaines plantes ont multi\u00adpli\u00e9 tout leur mat\u00e9\u00adriel g\u00e9n\u00e9\u00adtique. D\u2019autres chan\u00adge\u00adments dans les chro\u00admo\u00adsomes multi\u00adpli\u00e9s ont conduit \u00e0 la forma\u00adtion de fleurs. Ce d\u00e9ve\u00adlop\u00adpe\u00adment a d\u00fb avoir lieu plusieurs fois, ce qui montre la multi\u00adtude de plans de base de construc\u00adtion de fleurs.
\nCepen\u00addant, les plantes \u00e0 fleurs p\u00e9tri\u00adfi\u00e9es les plus anciennes n\u2019ont qu\u2019en\u00advi\u00adron 130 millions d\u2019an\u00adn\u00e9es et sont tr\u00e8s rares et il n\u2019y a pas beau\u00adcoup de recherches \u00e0 ce sujet. Elles se sont peut-\u00eatre d\u00e9ve\u00adlop\u00adp\u00e9es \u00e0 partir de foug\u00e8res d\u00e9tec\u00adtables depuis 400 millions d\u2019an\u00adn\u00e9es. Jusqu\u2019\u00e0 aujourd\u2019hui, les plantes \u00e0 fleurs ont une influence sur le d\u00e9ve\u00adlop\u00adpe\u00adment des insectes et vice versa.

Le climat est chaud tout au long de l\u2019an\u00adn\u00e9e. La terre ferme est libre de glace, donc le niveau de la mer est \u00e9lev\u00e9. L\u2019at\u00admo\u00adsph\u00e8re contient 1,5 fois plus d\u2019oxy\u00adg\u00e8ne et 4 fois plus de CO<\/span>2<\/sub> qu\u2019au\u00adjourd\u2019\u00adhui. La d\u00e9com\u00adpo\u00adsi\u00adtion du Gond\u00adwana se pour\u00adsuit. L\u2019Aus\u00adtra\u00adlie se s\u00e9pare de l\u2019An\u00adtarc\u00adtique, l\u2019Afrique se s\u00e9pare de l\u2019Am\u00e9\u00adrique du Sud, et l\u2019Inde se s\u00e9pare aussi.<\/p>\n","protected":false},"excerpt":{"rendered":"
