What is the effect of speciation on biodiversity?

• A. Decreases biodiversity
• B. Has no effect on biodiversity
• C. Increases biodiversity
• D. Stabilizes biodiversity

Answer: (C)

Speciation refers to the process by which new species arise, typically through the mechanisms of evolution such as natural selection, genetic drift, and reproductive isolation. This process plays a crucial role in increasing biodiversity. When a new species is formed, it adds to the variety of life on Earth, contributing to the overall richness of ecosystems.

As new species evolve, they can fill different ecological niches, which enhances the complexity and stability of ecosystems. More species within an ecosystem can lead to greater resilience against environmental changes and disturbances, as different species may respond uniquely to challenges such as climate change or habitat destruction. Therefore, the ongoing process of speciation is fundamental to the enhancement of biodiversity, fostering a more diverse array of organisms and interactions within communities.
