Scientists find worm species that "regenerate"

Like a movie! Scientists have succeeded in identifying four species of marine nematodes, under their evolutionary abilities There is the ability to revive your head after being beheaded.

The investigation is in the University of Maryland, and specify that the evolution process is from 10 to 15 million years ago for these species.

The study was based on the selection of 35 species nemeresis seamen located on the coast of the USA, Argentina, Spain and New Zealand, between the years 2012 and 2014.

There, the investigators verified it only four species have the ability to recover a full head, including the brain. How incredible is that?

The rebirth experiments has been applied to 22 species of marine nematic worms, only 8 species could regenerate the head and the forest repair complete individuals from the back of the body. From this sample, four species have already been known by researchers.

"It follows that the ancestor of this group of worms could not regenerate the head, but four separate groups later developed the ability to do so," Alexandra Bely, one of the study's authors, said.

The relevance of This scientific finding is that the rebirth of amputated body parts, This is not an old feature of the species, but it is believed that the majority have lost evolutionary quality in the process.

In addition, it will mean a very important advance for medicine, the capacity of the planaria, to restore its entire body from a small tissue tissue, the scientists have fascinated since the end of the 19th century.

These creatures can regenerate any cell or tissue they lack, whether they are muscles, neurons, the epidermis or the eyes.

What is the name of the gene that can reach it?

This is called the Notum, and scientists have established it in different species, ranging from sea anemones and even fruit flies. These investigations serve for various aspects of medicine in terms of regeneration specialty.
