The concept of adaptation is fundamental to the theory of evolution. The adaptationist perspective is a theoretical framework that seeks to explain the evolution of traits as a result of natural selection. In this article, we will explore the definition and meaning of the term adaptationist, its origin, and its associations in different contexts.
Definitions
The adaptationist perspective is a theoretical framework that seeks to explain the evolution of traits as a result of natural selection. An adaptationist is someone who subscribes to this perspective and seeks to explain the evolution of traits in terms of their adaptive value.
Origin
The term adaptationist was first coined in the 1970s by evolutionary biologist George C. Williams. Williams used the term to describe a group of biologists who were interested in the evolution of traits and the role of natural selection in shaping them.
Meaning in different dictionaries
The term adaptationist is not commonly found in dictionaries. However, the term adaptation is defined as the process by which organisms become better suited to their environment through genetic or behavioral changes.
Associations
The adaptationist perspective is often associated with the field of evolutionary biology. It is also associated with the idea that traits evolve because they provide some sort of advantage to the organism in its environment.
Synonyms
Some synonyms of adaptationist include evolutionary biologist, natural selectionist, and Darwinian.
Antonyms
There are no direct antonyms of adaptationist, but some opposing viewpoints to the adaptationist perspective include neutral theory and punctuated equilibrium.

The root word of adaptationist is adaptation, which comes from the Latin word adaptare, meaning “to fit or adjust.”
Example Sentences
- The adaptationist perspective suggests that traits evolve because they provide some sort of advantage to the organism in its environment.
- The adaptationist approach is often used to explain the evolution of complex traits, such as the human brain.
- Many evolutionary biologists consider themselves to be adaptationists, as they believe that natural selection is the primary mechanism driving evolution.
