Way Ahead In Evolution

Just a recent scientific study to show how we bacteria are centuries ahead of mankind in evolution:

Croatian scientists have worked out how a radiation-resistant bacterium that can exist in extreme conditions repairs damage to itself, a discovery that could provide clues about diseases such as cancer. The organism called Deinococcus Radiodurans is so hardy it can survive ionizing radiations 5000 times stronger than the level lethal to humans.

“Through evolution, the bacteria have developed a mechanism to precisely reconstruct their cell structure once the radiation stopped. For many years this has been a scientific riddle”, Ksenija Zahradka, a leading researcher in the study, told the news conference. “It is an extremely fascinating phenomenon to see how a cell itself can repair its fairly destroyed DNA. We will use this knowledge to try and find way how cells that are not so resistant could do the same.”

The scientists, whose findings were reported online by the journal Nature, described the two-stage method in which the bacterium rebuilds its genome.

Many diseases, including cancer, involve alterations to DNA and an inability to recover from the damage. “Therefore, any understanding of self-repair mechanisms could help in that regard. Now we will focus to see if there are other organisms which can do the same,” Mr. Zahradka said.

Deinococcus Radiodurans which means strange berry that withstands radiation, was discovered 50 years ago in a can of spoilt meat. It can survive in deserts or on other surfaces exposed to strong heat.

This is just ONE of our species. Hope humans get the idea of what can be expected from us if our demands aren’t met. The world cannot bear another war of the scale of X-MEN 3. And there won’t BE any X-MEN to save you this time.
