When you're packing for an adventure, what's the most important thing you'll need? If you don't want to
get lost, you'll need a map! Or better yet, a GPS. What about other animals, how do they know where they're going? While humans depend on technology to travel, some animals have something far more advanced. Some American scientists found that Chinook salmon (鮭魚)have a "built-in GPS" of the Earth's magnetic field (磁場).This means as soon as they are born they are able to direct themselves in the ocean (海洋).It acts like a big map inside their brain.
Scientists placed some baby salmon into a big swimming pool. To simulate the Earth's magnetic field, they put magnetic coils (線圈)all around the pool. Then, by changing the direction of the coils, the salmon began to change their own direction. They started to face in the direction of their ocean feeding area. This is a safe place in the ocean where salmon can find food to eat. When the scientists changed the coils to the opposite side, the salmon also turned in the opposite direction. Just by using their "built-in GPS", the salmon were able to find out the direction of their feeding area.
How did Chinook salmon get their "built-in GPS"? The scientists believe that their navigation (導航)skills came through evolution (進化).The fish that were able to reach the feeding area lived longer.

A. have their own magnetic field B. learn directions from their parents
