Adaptation Theory explores how organisms evolve over time to better fit their environments, emphasizing the dynamic interplay between genetic variation and environmental pressures. It underscores the importance of natural selection in shaping the traits of species, ensuring their survival and reproduction in changing habitats.

Adaptation Theory

Organisms evolve

Genetic variation refers to the differences in DNA sequences among individuals within a population, which is crucial for evolution and adaptation to changing environments. It arises from mutations, genetic recombination during sexual reproduction, and gene flow between populations, providing the raw material for natural selection to act upon.

Genetic Variation

Environmental pressures are external factors that can influence the survival, behavior, and evolution of organisms or systems. These pressures can be natural or anthropogenic, leading to adaptation, migration, or extinction in response to changing conditions.

Environmental Pressures

Natural selection is a fundamental mechanism of evolution where organisms better adapted to their environment tend to survive and produce more offspring. This process leads to the gradual adaptation of species to their environments over successive generations, driving the diversity of life on Earth.
