In what way does extinction contribute to evolutionary processes?

Extinction plays a significant role in evolutionary processes by providing opportunities for new species to diversify. When a species goes extinct, it often opens up ecological niches that were previously occupied. This can lead to the emergence and diversification of new species that can exploit those available resources. With reduced competition from the extinct species, surviving species may adapt and evolve in new directions, potentially leading to a greater variety of forms and functions within an ecosystem.

This phenomenon can be observed in the aftermath of mass extinctions, where the drastic reduction in biodiversity allows for rapid evolutionary change and innovation. This process helps shape the complexity and diversity of life on Earth, illustrating how extinction can act as a catalyst for evolutionary advancements.
