Probably to make movement easier and/or quicker. Earthworms use it today to move easier through soil.

The first animal phylum to have a circulatory system was the Annelida phylum, specifically the earthworm. Annelids have a closed circulatory system composed of blood vessels that transport nutrients and oxygen throughout the body.
Charles Darwin is credited with developing the theory of evolution by natural selection, which explains how species evolve over time through the process of adaptation to their environment. Darwin's groundbreaking work "On the Origin of Species" published in 1859 laid the foundation for our understanding of evolutionary adaptation.
Adaptation of some sensory functions, as in dark adaptation when objects not seen at first in dim light gradually become visible.the process by which stimulus energies are changed into neural impulses.
One of the first animals to develop a true body cavity was roundworms, also known as nematodes. This body cavity, called a pseudocoelom, helped provide support and structure to their bodies, allowing for more efficient movement and organ function.

Segmentation.
Annelids are the first animal phyla to have a true body cavity (coelom), which is enclosed by mesoderm. This cavity enables more complex organ systems and allows for greater specialization of body functions.
It was appeared in nematodes.Annelides had first true coelom.
segmentation
Annelids are segmented worms. Being segmented is what generally differentiate them from the other worms. One of the most basic example is an earthworm.
For your market segmentation a toll free number equipped with call management features lets you handle simultaneous incoming calls and take them to the right person.
Annelids, a group of segmented worms, have been known since ancient times, with early references in texts by Aristotle around 350 BCE. However, more systematic studies of annelids began in the 18th century, particularly with the work of naturalists like Carl Linnaeus, who classified many species. The formal recognition and classification of annelids as a distinct group occurred in the 19th century as biological sciences advanced.
The first cities in the world developed in Mesopotamia.
Yes, annelids belong to the protostome group of animals. Protostomes are a group of animals whose blastopore develops into the mouth first during embryonic development. Annelids, such as earthworms and leeches, exhibit characteristics consistent with protostome development.
The classifying information into groups that share common characteristics is called segmentation process. To do the segmentation in excel is, first of all, select the row or column that has similar data, second, click sort smallest to largest or the reverse one, then select subtotal and lastly click the outline button to create a data outline.
