Why are our pupils round? Why aren't they narrow and oblong, like cats🤔, for example? Of course, there are good reasons for this peculiarity! The vertical shape of the pupils is provided by two muscles (not one, as with us) and is necessary for better vision at night. Yes, it's that trivial. And, for example, the square or rectangular shape of pupils in cloven-hoofed animals is necessary to increase the degree of vision. They can see objects in a radius of about 320 to 340 degrees! But for humans, none of these features are vital. We can see 160-210 degrees and have average vision in the dark🙌🏻
