A gradual process through which living organisms undergo changes in morphology or functionality over many generations, ultimately becoming better adapted to their environments, emphasizing that this change is not necessarily a linear progression toward improvement.
The concept that all living beings have developed over time from primitive forms, reflecting a historical perspective of biological diversity and adaptation, which can also extend to societal and universal changes.
The development of systems, ideas, or entities over time, indicating an unfolding complexity or refinement, which can occur in various contexts beyond biology, including social structures and cultural dynamics.
Example:
絶滅は進化の一部である。
A scientific theory that explains how living organisms have developed and diversified over time through a process of gradual change and adaptation to their environments, often encompassing concepts of natural selection and genetic variation.
The philosophical view that all forms of life have originated from simpler ancestral species, transforming through evolutionary processes rather than being created in their current forms by a divine creator.
A framework established in the 19th century that posits that biodiversity results from a long-term process of transformation from primitive life forms into more complex organisms, fundamentally influencing various fields of science.

このことを背景知識として、ここで進化論生物学の現状についての考察に移ろう。
The process by which a single lineage diverges into two or more distinct evolutionary paths, leading to the development of new species.
A form of evolution where one species splits into separate species due to varying environmental pressures or adaptations, resulting in increased biodiversity.
The mechanism by which different groups of organisms evolve distinct traits and characteristics from a common ancestor over time, often in response to different ecological niches.
The branching of evolutionary lineages that occurs when populations of a species become isolated from one another, leading to the accumulation of differences that result in speciation.
A phenomenon in which two different species evolve in response to each other's adaptations and changes over time, often leading to a mutual influence on their evolutionary paths.
The evolutionary process in which distinct biological entities exhibit reciprocal adaptations, such as the relationship between flowering plants and their pollinators, where each influences the other's traits.
The interdependent evolution of different species that occurs due to their interactions, exemplified by the way certain plants may develop specific features to attract particular pollinators while simultaneously affecting those pollinators' evolutionary traits.
