Character Displacement

Character displacement, or trait divergence, refers to the evolutionary process whereby closely related species develop distinct traits or characteristics in response to competition for similar resources, thereby reducing niche overlap and promoting coexistence. This phenomenon often manifests in morphological, behavioral, or ecological differences that enhance the survival and reproductive success of the species involved.

Overview

Character displacement is a key concept in evolutionary biology that explains how species adapt to reduce competition for resources. When two species share the same habitat, they may evolve different traits, allowing them to exploit different niches. This process not only helps the species survive b...

Key Terms

Trait Divergence
The process by which two or more species evolve different traits.

Example: Darwin's finches show trait divergence in beak size.

Niche
The role or function of an organism within its environment.

Example: Different bird species may occupy different niches in a forest.

Natural Selection
The process where organisms better adapted to their environment tend to survive and produce more offspring.

Example: Faster rabbits may escape predators more effectively.

Adaptive Radiation
The rapid evolution of diversely adapted species from a common ancestor.

Example: The diversification of mammals after the dinosaurs' extinction.

Ecology
The branch of biology that deals with the relationships of organisms to one another and to their physical surroundings.

Example: Ecologists study how species interact in ecosystems.

Biodiversity
The variety of life in the world or in a particular habitat or ecosystem.

Example: Coral reefs are known for their high biodiversity.
