After centuries, people have figured out why snakes have such a long body.

• Do you know that the most interesting facts of life are most weird, funny and stupid yet bluntly very true facts.

Snakes - which featured animals with long filenames body, without any public expenditures, move by wriggling look very horror.

But have you ever wondered, why snakes have such a long body? In fact, the researchers also asked exactly the same, and until recently they found the answer.

Accordingly length of the solid body comes from only a single gene, bring tenOct4. That kind of work tweaking genes of stem cells and affect the body between the vertebrate species.

Solid body length of only from a single gene, called Oct4.

In solid, there is a stage in the process of evolution has made continuous Oct4 gene is activated for longer than normal animals. And this gene affects the embryonic development of the solid.

Dr. Rita Gulbenkian de Ciencia Aires Institute (IGC) of Lisbon, Portugal: "The formation of the body like a combination between the genes. The gene related to the body between activities , to form the tail genes can operate then. "

"With solid, we observed the gene Oct4 activity with longer periods of embryonic development stages, indicating that the body of the snake will be very long, while the tail is short" - Aires said.

There, experts set out this conclusion based on experiments from ... mouse. Specifically, mice with Oct4 gene generally have a longer torso.

Experts said the discovery of the gene Oct4 role could pose a new ray of hope for spinal cord injury recovery.

Dr. Moises Mallo, the research laboratory, said: "We identified the key factors allowing clones developed unlimited, as long as there are active genes. If can use, and some gene Oct4 another to reconstruct the spine, we will cure the ills related - which is extremely difficult to resolve with today's medicine. "
