This could be the biggest advantage of the white shark




(Newser)

For the first time scientists have decoded the genome of the Great White Shark, and the results show that humans can learn a lot from the long-lived creatures. The genes of the sharks seem particularly suited to heal their own wounds and ward off disease, [Wired reports . "These include DNA sequences that code for the loading of blood clotting agents, as well as scaffold proteins, which are responsible for determining the basic units of new meat." In short, the DNA can repair itself via the BBC. In addition, the sharks have 41

pairs of chromosomes compared to the 23 of humans, and this much larger genome means that the sharks have encoded things that humans do not have.

The genome helps to explain how sharks have survived hundreds of millions of years in dangerous waters, despite living relatively disease free despite their weight of up to 7,000 pounds per Science Daily . The sharks have a "surprisingly high number of genome stability genes" and seem to be capable of "genetic tuning" during their lifetime, says co-leader Mahmood Shivji. People, not so much. "Instability of the genome is a very important issue in many serious human diseases," says Shivji. He adds that studying the shark genome could shed light on diseases ranging from Alzheimer's disease to cancer and wound healing.
