INTERGRADATION Meaning and
Definition
-
Intergradation refers to a biological process in which two distinct species or populations gradually merge and blend together through the exchange of genetic traits. It occurs when the borders between two populations become less distinct due to frequent interbreeding or gene flow. This allows genetic material to move freely between the two groups, resulting in the formation of intermediate individuals that share characteristics of both original populations.
The concept of intergradation commonly occurs in the field of ecology, where it describes the gradual transition between different ecological communities or habitats. For instance, in a forest ecosystem, there might be areas where a wetland habitat transitions into a dry, upland habitat. In these transition zones, species from both habitats may interbreed, leading to individuals that possess a mix of characteristics from both wetland and upland species.
This phenomenon is often studied to understand the evolutionary dynamics between different species and their interactions with the environment. Intergradation plays a key role in shaping species distribution, genetic diversity, and the formation of new species. By studying intergradation, scientists can gain insights into the complex relationships between organisms and the processes that drive biological diversity in various ecosystems.
Overall, intergradation is a mechanism through which distinct species or populations can gradually merge and share genetic traits, resulting in the formation of intermediate individuals and transition zones between different habitats or ecological communities.

Etymology of INTERGRADATION
The word "intergradation" is derived from three Latin roots:
1. "Inter" - which means "between" or "among" in Latin.
2. "Gradus" - which means "a step" or "degree" in Latin.
3. "atio" - a suffix in Latin that indicates the action or process of.
Therefore, combining these roots, "intergradation" can be understood to mean the process or action of transitioning or blending between different degrees or steps.
