130 million years to today

Geolo\u00adgicial era: Meso\u00adzoic \/ Cretaceous<\/p>\n

The devel\u00adop\u00adment of flower\u00ading plants prob\u00adably began about 200 million years ago, with some plants creat\u00ading multiple copies of their entire genetic mater\u00adial in an indi\u00advidual (poly\u00adploidy). Further changes in the multi\u00adplied chro\u00admo\u00adsomes led to the form\u00ada\u00adtion of flowers. This devel\u00adop\u00adment must have taken place several times, which is shown by the large number of basic flower construc\u00adtion plans.
\nHowever, the oldest fossil\u00adized flower\u00ading plants are only about 130 million years old and very sparse, so their devel\u00adop\u00adment is not yet well under\u00adstood. They may have evolved from ferns that have been around for 400 million years. The flower\u00ading plants influ\u00adence the devel\u00adop\u00adment of insects and vice versa.<\/p>\n

The climate is consist\u00adently warm. The coun\u00adtry is ice-free, there\u00adfore the sea level is high. The atmo\u00adsphere contains 1.5 times more oxygen and 4 times more CO<\/span>2<\/sub> than today. Gond\u00adwana contin\u00adues to break apart. Australia separ\u00adates from Antarc\u00adtica and Africa from South Amer\u00adica, India also splits off.<\/p>\n","protected":false},"excerpt":{"rendered":"
