Key Concepts

Genetic Variation

Genetic variation refers to the differences in DNA sequences among individuals within a species. This diversity is essential for natural selection to act upon, as it provides the range of traits that might be advantageous when facing new environmental challenges.

Natural Selection

Natural selection is the process by which certain traits become more common in a population due to the increased survival and reproduction of individuals with those traits. It plays a critical role in determining which adaptations enable a species to thrive in changing conditions.

Environmental Change

Environmental change encompasses alterations in a species' habitat, climate, or ecosystem that can impose new selective pressures. The pace and extent of these changes influence whether a species can adapt in time or face extinction.

Phenotypic Plasticity

Phenotypic plasticity is the ability of an organism to modify its physiology, behavior, or morphology in response to environmental changes. This flexibility can provide a temporary buffer allowing populations to survive until genetic adaptations occur.

Population Dynamics

Population dynamics involves the factors that affect population size and structure, such as birth and death rates, migration, and genetic drift. These dynamics can impact a species’ capacity to adapt, as small or declining populations may have reduced genetic variability.

Evolutionary Timescales

Evolutionary timescales refer to the period over which genetic changes accumulate in a population. The rate of environmental change relative to the pace of evolution is crucial; rapid changes may exceed a species' capacity for genetic adaptation, while slower changes may allow for gradual adaptation.

Ecological Interactions

Ecological interactions, including relationships like competition, predation, and mutualism, shape the selective pressures experienced by species. Changes in these interactions can either facilitate or hinder a species’ ability to adapt to their environment.
