Complex Adaptation

A complex adaptation is a suite of coexpressed traits that together experience selection for a common function. Phenotypes are considered complex when they are influenced by many environmental and genetic factors and when multiple components must be expressed together for the trait to function.

Citrate Exploit

The ability of certain bacteria, specifically strains of E. coli in experimental evolution, to utilize citrate as a carbon source under aerobic conditions where they typically cannot.

Lenski's Experiment

A long-term evolution experiment led by Richard Lenski, observing the genetic changes in Escherichia coli bacteria over thousands of generations.

Oxygen Concentration

The amount of oxygen present in a particular environment, such as air or water, critical for the survival of aerobic organisms.
