Why do animals with large eyes run faster?

Researchers have found that animals with larger eyes than their body size will help it run faster, because large eyes provide better vision, are beneficial to animals when traveling. fast transfer.

Associate Professor Chris Kirk of the University of Texas at Austin said, 'Large-sized eyes are one of the important factors that marks visual ability and visual adaptive evolution. In vertebrates, an increase in eye size can benefit both vision (detailed vision) and sensitivity (vision in dim light) '.

Although some animals rely more on other senses, their eyes and vision still play an important role in most. This also seems very true for fast-moving animals like newspapers, horses . Having large eyes will help them have better vision to avoid hitting obstacles in the environment when they are moving very fast.

To demonstrate the effect of eye size on the ability of animals to run, the researchers collected measurements of eye size, body size and running speed of 50 mammal species. The results showed that 89% of eye size changes in mammals are due to their body mass and maximum running speed.

However, for humans it does not seem right. Although we have large eyes, our maximum running speed is slower than many other mammals.
