What is a Banded Snake? What is the Ancestry of the Banded Snake?
The world is full of wonders, and many creatures live on Earth. We commonly see those that run on the ground, swim in the oceans, and fly in the sky. However, the next creature we'll discuss lives in the surface soil – the ancestor of the earthworm.
I. The Ancestry of the Earthworm
When we talk about earthworms, many people are unfamiliar with them. But if we mention leeches, many people will know them. Earthworms are one type of these creatures, and they are called by this name. They can make many people shiver, although they have no attack on humans, but their damp bodies are very slimy.
The discovery of earthworms dates back to Darwin's time writing about evolution. At that time, people began to have curiosity about this small creature. It lives in various regions of the world, and it is rarely found anywhere.
Earthworms belong to the phylum Annelida. These creatures first appeared in the ocean. They are the sandworms we often hear about. These creatures are classified as polychaete worms. They have soft body shapes and lack a protective hard shell, making them easily attacked by other creatures. Moreover, the number of their fossils is also very scarce, which gives scientists fewer bases.
II. Common Ancestry of the Earthworm
Earthworms now live in the surface soil, feeding on ground leaves. However, its ancestor is the sandworm, which lives in the ocean and feeds on marine plants. It is called the smallest-brained animal. Nowadays, earthworms can no longer adapt to aquatic environments. When it rains, they will run out of the ground to breathe fresh air.
III. The Value of the Earthworm
For humans, earthworms are beneficial and harmless. They loosen the hard soil on the surface, making the soil more porous. They can also be used as medicine to treat diseases. Fishermen often use earthworms as bait to lure fish.
