Sea turtles have spent more than 100 million years honing impressive navigation abilities. After traveling thousands of miles from the beach where they were born, these ancient creatures can find their way back to that same location to build a nest and lay their own eggs. This process has led to several genetically distinct populations unique to a given nesting region across all seven sea turtle species—critical variations that could hold the key to better protection of sea turtles that face many threats from human activity.
