Sharks Exhibit Record-Low Mutation Rates, Challenging Adaptation

A recent study on epaulette sharks has discovered a mutation rate 10 to 20 times lower than that in mammals, demonstrating one of the lowest mutations rates in any vertebrate group. This contributes to their low cancer rates but hinders their ability to adapt to threats like overfishing and habitat loss. The finding highlights the importance of genetic variability for adaptation and evolutionary change. [Source](
