Scientists think that many — perhaps most — animals cannot see colors.The world is black and white to them.
Scientists believe that many animals, perhaps most, cannot distinguish colors. For them, the whole world has only two colors: black and white.
To find out if dogs could see colors, scientists gave dogs food ever time they played a certain piece of music.
In order to find out whether the dog can distinguish colors, scientists play the same song every time they feed the dog.
The dogs got ready to eat only when they hear this piece of music.
The dog is ready to eat as soon as they hear this song.
They did not get ready to eat when they heard other pieces of music.
And when they hear other songs, they will not be ready to eat.
Then the scientists gave the dogs food every time they showed them a certain color.The dogs got ready to eat when they saw this color.
However, scientists showed the same color every time they feed the dogs. Dogs prepare to eat when they see this color.
The scientists then showed the dogs another color.Again the dogs got ready to eat.The colors were all the same to them.
Next the scientists showed the dogs another color. They are ready to eat again. For dogs, all colors are the same.
Colors are not all the same to monkeys, however.
However, for monkeys, the colors are not exactly the same.
For example, if we put food in a red box, and do this every day, a monkey will always go to the red box to get the food.
For example: If we put food in a red box and do this every day, the monkey will go to the red box to get the food.
