Question

How do humans perceive the world they live in, and how does this differ from other mammals?

Answer 1

Human beings differ in many ways to other animals and mammals. In contrast to the human beings, mammals have only two types of cones, creating a similar color perception to humans with red-green color blindness. And they are mostly dependent upon the color to coordinate with their surroundings rather than complicated communication signals like human beings do. For instance, scarabs are the only species that can see and reflect circularly polarized light.
According to scientists scarabs use as a hidden communication channel. Let’s consider a leatherback sea turtle that sees the world in 2.5 times faster than human beings. Similarly, a fly’s eye sends updates to its brain far more frequently than a human’s eye does, and its mental processes are much more rapid than humans or another mammal.
