Earth was createdEarth is struck by Theia and creates the moonOver 1.5 billion years Earth keeps getting hit by asteroidsLife startedEarth cools and gains waterEarth Become mostly or completely covered in waterLuca DecendedFirst large land mass emergesEarth freezes over becoming the first snowball earthEukaryotic cells come into beingEukaryotic cells evolve and develop sexual reproductionEukaryotic cells engulf photosynthetic bacteriaMulticellular organisms ariseEukaryotes splits into the ancestors of modern plant, fungi and animalsFirst recognisable animal formedFungi evolve multicellular body plansEarly multicellular animals undergo their first split into sponges and Eumetazoa.Placozoa breaks away from the rest of the EumetazoaAnimals evolve bilateral symmetryThe Bilateria undergo an evolutionary split into protostomes and deuterostomesEdiacarans appearAmbulacraria breaks off of deuterostomeschordates first appearEdiacarans die outThe Cambrian explosion beginsThe first true vertebrates appeartrilobites appearConodonts appearPlants begin colonising the landParasites are aroundanimals were exploring the landThe bony fish split into the lobe finned fish and the ray finned fishcoelacanths split from the lobe finned fishthe lungfish split from lobe finned fishplants with elaborate root systems that stabilize the soil growInsects appearplants evolve woody stemsfour-legged animals or tetrapod's appearThe oldest fossilised tree dates from this periodTiktaalik an intermediate between fish and four-legged land animals appeartetrapods make it on landthe amphibians split off of tetrapodssauropsids and synapsids split off from tetrapodsa group of therapsids called the cynodonts evolve and becomes the first mammalsThe Permian period ends with the greatest mass extinction including the last of the trilobitesas the ecosystem recovers dinosaurs rule the earththe ammonites evoloveProto-mammals evolve warm-bloodednessearly dinosaurs are already evolving into birdsthe Triassic period comes to an ends and another extinction event happensThe first split occurs in the early mammal population.Epidexipteryx livesplacental mammals split from their cousins the marsupialsArchaeopteryx the famous “first bird” livesEoconfuciusornis a bird rather more advanced than Archaeopteryx livesFlowering plants begin growingThe Cretaceous dinosaurs reach their peak in sizeThe giant sauropods Argentinosaurus and Patagotitan livesThe oceans become starved of oxygen27% of marine invertebrates are wiped outThe ancestors of modern primates split from the ancestors of modern rodents and lagomorphsGrasses evolveThe Cretaceous-Tertiary extinction wipes out a swathe of speciesThe primates split into two groups, known as the haplorrhines, strepsirrhinesThe tarsiers, split from the rest of the haplorrhines: the first to do soThe Palaeocene-Eocene Thermal Maximum happensArchicebus, one of the earliest primates livesone group of artiodactyls evolves into whales. Early forms include Pakicetus.Indohyus livesThe famous fossilised primate known as “Ida” livesEarly whales called protocetids liveThe platyrrhines become the first simians to diverge from the rest of the group, when they cross the Atlantic too South America.Some plants evolve C4 photosynthesisApes split from the monkeys and diversify.Gibbons become the first ape to split from the othersThe ponginae branch off from the other great apes, spreading to southern Asia while their cousins remain in AfricaGorillas branch off from the other great apesThe ancestors of humans diverge from those of their closest relativesOur human genus, Homo, appears in Africa.A 700-kilogram rodent called Josephoartigasia monesi livesPériodes
The Great oxidization event happensEarth freezes over againThe placental mammals split into their four major groups: the laurasiatheres, euarchontoglires, Xenarthra, afrotheresfish split into the bony fish and cartilaginous fishFish with teeth appearThe Late Ordovician mass extinction happensThe Late Devonian mass extinction occurspelycosaurs evolve into therapsids and eventualy replace all pelycosaurs
