Basic Timeline of the Planet of Eile

 

Note: "Modern class"- nowaday clades

5.12 billion years ago: the planet begins formation. Planetary collisions with a planet at the time causes a 170°(10°) axial tilt and a result a capturing of 2 large asteroid moons , Vera and Nadyezhda, both being 700km in diameter as stated in the previous entry.

5.0 billion years ago: Eile would fully consolidate.

4.512 billion years ago: first undisputable evidence of Eile's life would be found. 

3.56 billion years ago: eukaryote-analogues form. 

1 billion years ago: first multicellular life evolves. 

700 million years ago: a period of mass extinctions and and conditions caused by the unpredictable tides caused by the captured asteroids forces the multicellular life to diversify and speciate. As well as this, small photosessilids begin coming on to land and the apothemaites form and rapidly diversify underwater, with the Caputicentralisid, appendixaform, and Duopeda classes rising rapidly. 

600- 450 million years ago: Vertebrate forms begin transition onto land, descending from basal mesoskeletal and exoskeletal(more similiar to crocodilian hide than classic exoskeletons) mobile bilaterian apothemaites(Caputicentralisids, Appendixaforms, and dyopodia) , during this stronger tides which are reminiscent of the strength of our modern moon takes place, albeit still unpredictable, this unpredictability is what brought these basal small mesoskeletal and "exoskeletal" clades onto land, as with weaker and yet more unpredictable tidal pools, you were most likely stuck in them for longer, needing to evolve lungs to carry out atmospheric respiration and if a tidal pool completely wiped out, you needed evolve legs. This process took over dozens of millions years, with only a full vertebrate-form transition onto land finally taking place around 450 millions years ago, with all the invertebrate-forms having been on land way longer and way earlier.

450 -350 million years ago: The Caputicentralisid clades dominate the land and diversify and speciate into various advanced herbivorous and predatory forms. However this also causes an extinction of the large invertebrate forms at the end of this era. In this era, a transition of ectothermic Caputicentralisida into endothermic Caputicentralisida begins, as well as the major groups of terrestrial bilaterian Apothemaites (Caputicentralisida, Dyopodia, Appendixaforma) develop true endoskeletons and lose exoskeletons/mesoskeletons. 

As you can see, tidal movements have rather slowed down the development of terrestrial vertebrate forms on Eile, as they are not as strong as seen on Earth.

350- 250 millions years ago: The titan era of Anapazoan life , largest Anapnoils develop on Eile, mainly from the Caputicentralisid clade.

249 million years ago: A meteor hits Eile causing a mass extinction of dominant caputicentralisid clades. 

200 million years ago: Modern caputicentralisid, Appendixaform, and Duopod clades arise. 

Today: You are reading Eile.

The Great Tomorrow: "The Great Tomorrow" will be getting a post sometime in the future but briefly in 5 words; History of Humanity and Eile.
