4.5 Eonis (billion of years) it does this Mrs. it had origin. Exactly (it is made for saying) 9.5 Eonis after the Big Bang. They owed some however to pass others 3.95 of Eoni, that, 550 million years ago, the first living organisms (in a word our ancestors ) they made their apparition on the planet. It concerned animals from the soft body that they were developed in the seas shutters jurassic whose fossils are each other preserved in the sandstones of Ediacara. They were in practice the modern jellyfishes (photo here under). The first true ancestors of the man (Astralophitecus afarensis ) they made their appearance ago on the Earth 2 million years, even if then the kind from which we come down (homo sapiens sapiens ) it appeared 35.000 years ago in Europe and in Africa, but this and recent history. Skipping, the first 9 billion of years of life of the Universe, go however to see since then (that is 5 Eonis does) to today like one is evolved the situation. The solar System one is fully grown 5 Eonis it does (as soon as mean billion of years before the Earth), the most ancient Microfossilis go up again to 3.56 Eonis it does, while manufacturing Bacteria of oxygen, Stromatolitis and blue Algas to 3.4 Eonis it does. The Scxhermo of ozone (very vituperated) one is fully grown 2.4 Eonis it does, while the Oxygen in the atmosphere 2.2 Eoni does. The first breathable atmosphere and of 1.7 billion years ago, and the first aerobic organisms became abundant not a lot of time afterwards. these organisms were mono cell (here that end had made the famous first cell of theological memory) and you/he/she could have spent another billion (but you know it that if a man worked, counting a number to the second, for 8 hours a day you/he/she would need of 33 years to arrive to the billion) of years before they were evolved in animals to more cells (that he doesn't want to say one that has more portable telephones). And arrived now, 550 million years ago note, to the first living organisms, that is animals from the soft body the Jellyfishes from which we come down.
