The theory of gradual change in a species over time, often associated with Charles Darwin's theory of evolution, posits that species evolve through small, incremental changes rather than sudden transformations. This process, known as gradualism, suggests that these minor variations accumulate over long periods, leading to the development of new species. Natural selection plays a crucial role in this theory, as advantageous traits become more common in a population, while less beneficial traits diminish. Ultimately, this continuous adaptation helps species survive and thrive in changing environments.

Adaptation is when a species is able to change over time to new changes in their environment.

Belief in the theory that species change over time was hampered primarily by the prevailing scientific and religious views of the 18th and early 19th centuries, which emphasized the fixity of species and a static view of creation. The lack of concrete fossil evidence and the dominance of the idea of divine creation further reinforced skepticism. Additionally, the complexity of biological mechanisms, such as heredity and variation, was not well understood, making it difficult for people to accept gradual change as a plausible explanation for the diversity of life.
The theory of evolution proposes that species can change over time through processes like natural selection, genetic drift, and mutations. These mechanisms drive variation within populations, allowing those individuals with advantageous traits to survive and reproduce, resulting in changes in the species over successive generations.

Evolution
The theme that reflects the idea of gradual change in the characteristics of species over time is evolution. Evolution is the process by which species change and diversify over time due to genetic variation, natural selection, and other mechanisms. It explains how species adapt to their environment and how new species arise.
