What genetic adaptations (nature) might help turtle survive risks? (list 2 examples)

What is .. 

- Heat tolerance – Some embryos survive higher temperatures better than others.

- Navigation abilities – Changes in magnetic field sensitivity may help turtles find new, safer nesting grounds.

- Shell strength – Some populations of Loggerheads have developed thicker shells, possibly as protection against predators and human interference.
