Macroevolution

In biological life, macroevolution comprises the large-scale evolutionary trends above the species level. One mechanism is species selection, whereby specis either survive or become extinct through time. Thus large-scale trends are determined by which species survive.

Macroevolution is an outcome of the interaction between microevolutionary processes operating within myriads of individual populations and species, on the one hand, and the global biospheric enviroments evolving on specific stable and old space or enclosed habitats or - in the case of garden worlds - in various continents and oceans over millions of years, on the other.
