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 livesPeríodos
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
