It is not without reason that human beings can later occupy the position of the highest living creatures on the earth, and we have great creativity and action to help us complete many unimaginable tasks. Most of the creatures naturally cannot be useless, they also have special abilities that other creatures and even humans do not have, and even become the object of our human imitation and research. Today I want to introduce you to an ability that everyone dreams of – regeneration.
As we all know, most living organisms are difficult to recover when they are damaged or even missing, and even lose their lives in severe cases. There is a creature called planarians, and their regenerative ability may be one of the strongest on earth. Planarians have a terrible way of hunting, they will wrap their bodies around their prey and suck up their prey with their mouths on their stomachs, but what we are focusing on today is their amazing regeneration ability, even after the head is cut off, they can regenerate without dying.
Planarians are a type of cave worm, which is recognized by scientists in the world as the most regenerative organism, no matter how scientists cut their bodies or organs or even brains, each part that is shredded can regenerate a new body. The most extreme data is that a scientist once cut a planarian into the size of 271 parts, and it can still regenerate a new body, which is almost even if it is not a blood rebirth.
Scientists have been working on this near-invincible regenerative ability of planarians, and finally found that the secret of all this comes from a special stem cell in the body of the planarian, which can migrate, proliferate and differentiate in the body of the planarian, spread throughout the entire body of the planarian, accounting for 25%-30% of the cell number of the planarian, so as long as any part of the body has this special stem cell, it can have the ability to regenerate.
Broad-headed planarians
Recent research has discovered a secret of planarians: a scientist put the planarians in a petri dish to train them in the ability to find food; then cut off the heads of these planarians, but after their heads are re-grown, the new planarians will still have the skill of finding food, indicating that the body of the planarians has a memory function, as for the storage and use of memory function, scientists still have no clue.
Flat-horned planarians
Nature has always been the object of human learning, until now our understanding of nature is still less than one, and these inferior creatures in the eyes of human beings still have abilities beyond human imagination, which is worth learning and studying.
