Every year, hundreds of giant sea turtles swim hundreds of miles from their homes near Brazil to a tiny island in the Atlantic Ocean in order to find their mates. For years, scientists tried to understand how the turtles could find their way every time, from so far away. It was a tiny island, and even airplanes sometimes had trouble finding it. What do you think it was?? Once upon a time, a very, very long time ago, when the dinosaurs lived, that little island was closer to Brazil, and it used to be a short swim from where the turtles lived. It is in their memory to know where to go, even though they themselves don't remember, they have a memory together of the way that it used to be, and they heard stories from their turtle parents about that special place. Each year, they go there together to remind themselves of the trip that their ancestors used to take. Tonight, we are just like those turtles.
