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 example the 'Jurassic System' of rocks was formed during the 'Jurassic Period' (between 201 and 145 million years ago). The following table includes all currently recognized periods. The table omits the time before 2500 million years ago, which is not divided into periods. See Geologic time scale#Proposed Precambrian timeline for another set of periods 4600–541 MYA. In a steady effort ongoing since 1974, the International Commission on Stratigraphy has been working to correlate the world's local stratigraphic record into one uniform planet-wide benchmarked system. American geologists have long considered the Mississippian and Pennsylvanian to be periods in their own right
