E.V.O.: Search for Eden the tedious gameplay and subpar graphics. "E.V.O.: Search for Eden" is a side-scrolling platformer action game where players must navigate a creature of their own design across a number of environments resembling Earth's past. The game is divided into five distinct geological periods: the Cambrian Period and the Ordovician Period of the Paleozoic Era ("The World Before Land") from 500 million years ago to 450 million years ago, then the Carboniferous period ("Early Creatures of Land"), the Mesozoic Era ("Age of Dinosaurs"), the late Neogene period ("Ice Age"), and finally the early Quaternary period ("Early Man"). Each period has its
Geological period though the ICS now recognises them both as 'subperiods' of the Carboniferous Period recognised by European geologists. Cases like this in China, Russia and even New Zealand with other geological eras has slowed down the uniform organization of the stratigraphic record. Notable changes Geological period A geological period is one of several subdivisions of geologic time enabling cross-referencing of rocks and geologic events from place to place. These periods form elements of a hierarchy of divisions into which geologists have split the Earth's history. Eons and eras are larger subdivisions than periods while periods themselves may be divided into epochs
