Definition
Extinction refers to the complete disappearance of a species from Earth, which plays a critical role in evolution by allowing for the reallocation of ecological niches and the emergence of new species through adaptive radiation in response to changing environments.
Summary
Extinction is a vital process in evolution, allowing for the emergence of new species and the adaptation of life to changing environments. It can occur naturally or be accelerated by human activities, leading to significant biodiversity loss. Understanding extinction helps us appreciate the delicate balance of ecosystems and the importance of conservation efforts. Mass extinction events have reshaped life on Earth, leading to the rise of new species through adaptive radiation. By studying extinction, we can better understand the evolutionary process and the critical role that biodiversity plays in maintaining healthy ecosystems. Conservation strategies are essential to prevent further extinctions and protect the planet's rich biological heritage.
