The great white shark, whose scientific name is Carcharodon carcharias, boasts a very large genome, 1-1/2 times bigger than the human genome. Just the opposite seems to be the case for this shark, thanks to adaptations in genes involved in preserving genome integrity. This species, star of the 1975 Hollywood blockbuster “Jaws” and its multiple sequels, roams the world’s oceans, primarily in cool coastal waters. The great white shark also displayed genetic adaptations in several genes that play fundamental roles in wound healing. For example, a key gene involved in producing a major component of blood clots was found to have undergone adaptations.
