How does overspecialization cause extinction?

Overspecialization can lead to extinction by making a species overly reliant on a narrow range of resources or specific environmental conditions. When changes occur—such as habitat loss, climate shifts, or the introduction of new competitors—overspecialized species may struggle to adapt or find alternative resources, leading to population decline. Additionally, their limited genetic diversity can reduce resilience to diseases and environmental changes, further increasing extinction risk. Thus, overspecialization can severely limit a species' ability to survive in a changing world.
