Key Concepts

Ecological Succession

Ecological succession is the process by which the species composition of an ecological community changes over time, usually following a disturbance. This process leads to a gradual recovery of an ecosystem, transitioning from pioneer species to a more stable climax community.

Natural Selection

Natural selection is the evolutionary process in which organisms with traits that are better adapted to their environment tend to survive and produce more offspring. Over time, this leads to the accumulation of beneficial traits in a population, forming the basis of adaptation and speciation as proposed by Darwin.

Biological Magnification

Biological magnification refers to the process by which the concentration of toxins or pollutants increases as it moves up the food chain. This occurs because compounds that are hard to break down accumulate in organisms and become more concentrated in predators at higher trophic levels.

Theory of Use and Disuse

The theory of use and disuse, historically associated with Lamarckism, posits that traits developed from an organism’s regular use or lack thereof can be passed on to its offspring. Modern evolutionary biology largely rejects this theory in favor of genetic inheritance and natural selection.

Punctuated Equilibrium

Punctuated equilibrium is a theory in evolutionary biology that suggests species experience long periods of stasis interrupted by short bursts of rapid evolutionary change. This concept contrasts with the gradual pace of change traditionally associated with natural selection.
