Details

Sense（1）

In ecology theory, the principle of competitive exclusion states that multiple species in competition for the same resource cannot coexist, as even the slightest advantage of one species over the other is successively amplified; a mechanism referred to as “rich get richer” or preferential attachment. This eventually leads to the extinction of the inferior species.
