How have earthworms evolved over time?

Answer 1

Earthworms have evolved over millions of years to adapt to various ecological niches, developing features that enhance their survival and reproduction in soil environments. Their segmented bodies allow for efficient movement through soil, while the ability to consume and break down organic matter helps in nutrient cycling. Additionally, earthworms have developed specialized structures, such as the clitellum for reproduction, and various adaptations to tolerate different moisture levels and soil types. These evolutionary changes have made them vital contributors to soil health and ecosystem functioning.
