When your worms split in two to act as two separate beings We have heard many myths about it. There are those of us who did brutal experiments on the street as children.

If you skipped biology class, some creatures like snails and worms We’ll tell you how they keep moving when their limbs are chopped off and whether new individuals are indeed formed from the severed limbs.

Regenerative abilities evolved over 500 million years ago.

From an evolutionary perspective, regenerative abilities were first more than 500 million years ago It is thought to have evolved even earlier than the Cambrian period. So how does this renewal process take place?

Cells migrate to the injured area.

If a limb has the ability to regenerate, the cells that migrated to that area immediately after amputation will fuse. a droplet called “blastema” they form. The cells of this droplet begin to differentiate into muscle/cartilage and develop into new tissues.

The regeneration process continues until all the structures of the regenerated part are differentiated. cells that grow over time a complete, straight leg They take shape and eventually run out. The development time can vary from organism to living thing.

If worms divide, can both parts really move separately?

Worms have a head and a tail, although we can’t tell them apart when we look at them. The head of a worm always surrounds the animal, called the clitellum. at the end closest to the swollen strip is found.

So essentially, when a worm splits in two, two new worms are not formed. If the worm’s head is cut off from the back of the clitellum, it can survive and can regenerate the queue. But the worm’s original tail cannot form a new head. Worms can even leave their tails to escape their predators.

Axolotls’ regenerative abilities are so advanced that they can close the wound in hours!

When a limb of cute axolotls, a kind of salamander, is amputated in just a few hours they have the ability to regenerate fast enough to close the wound there. They can even regenerate their brains without scarring!

Psycho snails take things to the next level!

Two types of sea snails, cut yourself and go to the next level shocked the researchers. They could move “according to their heads” by chopping off their own heads.

It has even been discovered that they can throw everything but their heads, including their major body organs. According to the study, the animals’ necks had a “predetermined break flat There were grooves that looked like

They regained their former appearance in three weeks.

One third of the animals’ heads when they carefully tie a nylon thread around the snails’ necks fantastic acting Went on.

Not only did his wounds heal within a day, but within seven days the heart and other vital organs grew back into new bodies that had grown from head to toe. Within three weeks their bodies are completely exhausted to its old state returned. In the research report “Without heart and other important organs It’s unclear how the head survived.
