Essay / The importance of earthworms - 1007
The full Nefertiti of Egypt declared them sacred. Aristotle called them the digestive tract of the world. Charles Darwin believed that they played an important role in the history of the entire world. Which animal has aroused the admiration of these celebrities? The common or garden earthworm.
