From about 1900 to 1960, however, understanding of succession was dominated by the theories of Frederic Clements, a contemporary of Cowles, who held that seres were highly predictable and deterministic and converged on a climatically determined stable climax community regardless of starting conditions. However, the evolutionary origins of animals are likely to be significantly more ancient.

Changes can also occur by microbial succession with variations in water availability and temperature. What Is the Difference Between Primary and Secondary Ecological Succession? While pioneering succession involves the colonization of a location that has been affected by ecological damage, primary succession is a better answer since it refers specifically to vegetation colonizing a location in which soil is absent (such as after a volcanic eruption). Species that arrive first in the newly created environment are called pioneer species, and through their interactions they build a simple initial biological community.
