  • 1500 BCE

    1st Eukaryotes

    Ordovician-Silurian Extinction

    Ordovician-Silurian Extinction
    About 83% of all life was wiped out. Glaciation and rising sea levels are noted to be the most influential causes of this extinction.
  • 364 BCE

    Late Devonian Extinction

    Late Devonian Extinction
    It is estimated that 75% of life was wiped out during this period. The heartyness of the creatures that survived actually helped form the first homosapiens. Without it we may not have been here today
  • 270 BCE

    Pangaea forms

    Pangaea forms
    Pangaea forms and most land on Earth is all together as one big supercontinent.
  • 251 BCE

    Permian–Triassic extinction

    Pangaea breaks apart

    Pangaea breaks apart
    The massive supercontinent, Pangaea, breaks apart and splits into our modern day continents.
  • 200 BCE

    Triassic–Jurassic extinction

    Triassic–Jurassic extinction
    It is believed that during this short peroid, there were many stages of the extinction. asteroid impact, climate change, and flood basalt eruptions are all to blame for it.
  • 65 BCE

    Cretaceous–Paleogene extinction

    Cretaceous–Paleogene extinction
    Probably the most well known extinction, the Cretaceous–Paleogene extinction wiped out the dinosaurs. However it allowed for the evolution of mammals to live on land and on sea
  • 7 BCE

    1st Homosapiens

    1st Homosapiens
    Humans first evolved into the people we are today about 7 millon years ago. However it wasn't till about 3 million years ago that we first started to use rock tools.
