Article 16: In volume 17, page 350 – at about 2/3 of the distance between the Big Bang and Now – we come across the birth of our Sun, of our Solar System and of our planet Earth.
Volume 17: Page 350, at about 2/3 of the distance between the Big Bang and Now: The birth of our Sun, of our Solar System and of our planet Earth.
A bit later the Moon comes into existence, after a crash with a large morsel, about the size of Mars, with the Earth.
Volume 18: The Earth cools down, the oceans are filled up with water condensing and water brought to us by meteorites. We detect the first signs of life on Earth, thermophilic, 113 degrees Celsius heat-loving bacteria. Some like it really hot! They freeze already at 55 degrees Celsius, above zero!
Volume 19: After one billion or 1,000 million years the infernal Hades period comes to an end. Slowly, slowly, a crust begins to grow around the Earth. 3,500 Million years old stromatolites fossils from this period are now to be found, for example in Warrawoona, Australia.
Volume 20: 3,200 Million year old fossilized cyanobacteria from this period are now to be found, for example in South Africa, in the Fig Tree Formation.
Volume 21: The crust around the Earth is ready.
Volume 22: Thanks to the oxygen that the cyanobacteria continuously pump as waste in the Earth’s atmosphere, a protective ozone layer is beginning to form around the Earth. It provides protection to the early life against the destructive ultraviolet radiation from the Sun.
In case the bacteria had not done this, then life on Earth probably would not have developed. Now, however, life is evolving exuberant and abundant. Unmistakable new life forms are arising, eukaryotes, and there is a transition from unicellular to multicellular organisms.
Volume 23: Bacteria begin to inhabit the continents.
Volume 24: Start of one of the major global glaciations: Iceball Earth. Some like it really cool! Formation of the supercontinent Rodinia. For the first time there is sexual reproduction, in which genetic material from two individuals comes together. This accelerates the evolutionary process.
Volume 25: We are almost done, just one more volume! And what about trees and fishes and reptiles and birds and flowers and dinosaurs and horses and cows and monkeys and humans like you and me?
We will outline all of them in the next 30 episodes.
We will have a closer look at the content of this one volume 25 and investigate more in detail what is happening in the different geological periods mentioned there on:
