Delší časová perspektiva nám umožňuje lépe pochopit současnou strukturu ekosystémů a jejich diverzitu. Paleoekologie se zabývá studiem vztahů mezi organismy a rekonstrukcí ekosystémů v geologické minulosti na časových škálách stovek či tisíců let. V článku si představíme různé pohledy na fungování přírody z hlediska její přirozenosti, kterou můžeme hledat v různých fázích historického vývoje.

A long-term perspective enables us to better understand the present-day ecosystem structure and its diversity. Paleoecology studies the relationship between organisms and performs ecosystem reconstructions in the geological past on timescales of centuries and millennia. In this paper we explore dif­ferent views of nature’s functions in terms of their naturalness, which can be found in various phases of historical development.
