According to this concept species are group of interbreeding organisms .... which is in reproductive isolation with species....

Ernst Mayr's Biological Concept of Species
Ernst Mayr, a prominent biologist of the 20th century, significantly contributed to our understanding of species through his biological concept. Mayr's definition emphasizes the role of reproductive isolation in the formation of species.
Key Components of Mayr's Concept
- Biological Species Definition:
- A species is defined as a group of populations that can interbreed and produce fertile offspring.
- Members of the same species share a common gene pool.
- Reproductive Isolation:
- Essential to Mayr's concept, reproductive isolation prevents different species from interbreeding.
- It can occur through various mechanisms, including:
- Temporal isolation (different mating seasons)
- Behavioral isolation (different mating rituals)
- Mechanical isolation (incompatible reproductive structures)
Types of Reproductive Isolation
- Prezygotic Isolation:
- Mechanisms that prevent fertilization from occurring.
- Examples include habitat isolation, temporal isolation, and behavioral isolation.
- Postzygotic Isolation
Importance of Mayr's Concept
- Understanding Biodiversity:
- Mayr's concept helps explain the vast diversity of life on Earth.
- Conservation Efforts:
- Insights into species boundaries are crucial for conservation strategies and biodiversity protection.
In summary, Ernst Mayr's biological concept of species centers on the ability to interbreed and the significance of reproductive isolation, providing a framework for understanding species diversity and interactions in the natural world.
