Succession

Definition

noun, plural: successions

1. (general)

(a.) The act of following in order or sequence.

2. (ecology) The progressive replacement of one dominant type of species or community by another in an ecosystem until a stable climax community is established.


Supplement

The word succession was first used by the French naturalist Adolphe Dureau de la Malle to refer to the vegetation development after forest clear-felling.

Ecological succession has an essential role in changing the composition or structure of a community. For instance, a new community of forest trees introduces shade to its ecosystem, or a previous community of vegetation that changed the fertility of the soil.

Succession may arise from the formation of new, unoccupied habitat (e.g. a lava flow or a severe landslide). This kind of succession in which the sequential development of plant or animal communities in an area where no soil initially exists is called primary succession. Succession may also be initiated by a disturbance of an existing community (e.g. fire, severe windthrow, logging). This kind of succession where communities develop in areas where soil already exists is called secondary succession.


Word origin: L. successio:
Related forms: successive (adjective), successional (adjective), successionally (adverb), succession (noun).
Synonym: ecological succession

Re: mutations and dependencies

... it was evidence for evolution, just that it didn't falsify the theory. However, you did make a good point. There are points at which the supposed succession becomes difficult to track, which makes the theory more difficult to falsify. Genetics/the very existence of DNA proves it never happened, ...

Re:

... untestable, but the theory of evolution gets much more specific than that. According to the theory of evolution, the fossil record should reveal a succession. A fossil that violates this would falsify the theory. The theory of evolution also now rests on genetic evidence. Organsisms that should ...
