Is this the most advanced creature on Earth? Via the Telegraph:
British researchers believe that the worms, which live in ponds and lakes, could live forever after examining their ability to repeatedly regenerate.
“Our data satisfy one of the predictions about what it would take for an animal to be potentially immortal,” Aziz Aboobaker, who led the research. “The next goals for us are to understand the mechanisms in more detail and to understand more about how you evolve an immortal animal.”
Flatworms, known as planarian worms, have long fascinated scientists because they have an extraordinary ability to regenerate. A planarian worm split lengthways or crossways will regenerate into two separate living worms. The researchers found that flatworms can continuously maintain the length of a crucial part of their DNA, known as telomeres, during regeneration.
