Overview

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...

Key Terms

Extinction
The end of an organism or a group of organisms.

Example: The extinction of the dodo bird occurred in the 17th century.

Natural Selection
The process where organisms better adapted to their environment tend to survive and produce more offspring.

Example: Darwin's finches are a classic example of natural selection.

Mass Extinction
A widespread and rapid decrease in the biodiversity on Earth.

Example: The Permian-Triassic extinction is known as the Great Dying.

Adaptive Radiation
The rapid evolution of diversely adapted species from a common ancestor.

Example: Darwin's finches evolved from a single ancestor into multiple species.

Biodiversity
The variety of life in the world or in a particular habitat or ecosystem.

Example: Coral reefs are known for their high biodiversity.

Ecological Niche
The role and position a species has in its environment.

Example: A bee's niche includes pollinating flowers.
