Why Can Dogs See Things Humans Can't? Scientists Offer an Explanation
Belonging to the Chordata phylum, the Vertebrata subphylum, the Mammalia class, the Therian infraclass, the Carnivora order, the Caniform suborder, and the Canidae family, also known as 'dog' in Chinese. Dogs are distributed worldwide. Scientists believe that dogs were derived from early humans through the domestication of wolves, with domestication dating from 40,000 to 15,000 years ago. They are called 'human's most faithful friends'. They are the most raised pets, and their lifespan is approximately 12 to 18 years.
If you have ever raised a dog, you must have experienced something like this: the dog suddenly barks at a particular place. However, when a person uses their eyes to look, there is nothing at the place the dog is looking at. So, why can dogs see things that humans cannot?
Regarding this, scientists have also explained that dogs' eyes can indeed see things that humans cannot, such as ultraviolet and infrared light. Dogs' eyes can see these, and because dogs cannot distinguish colors, many things that seem normal to human eyes will appear different to dogs' eyes, as shown in the picture above.
So, why do dogs bark after seeing these things? This is mainly due to the dog's brain. Because the dog's brain is not well-developed, after the eyes receive information and transmit it to the brain, the brain only processes the information simply and sends it back, so whether it is a 'big matter' or a 'small matter', as long as the dog sees something for the first time, they will bark without stopping.
