some caves are so dark they do not need eyes
I think to make it valid, your second premise would need to be "Only animals have eyes". The statement "All animals have eyes" allows that there could be something that has eyes that is not an animal, so it does not require the conclusion tht all people are animals.
YES
For the same reason other animals do - they still need to see !
They do not need eyes, whichwould not work anyway, though many have vestigial eyes. The darkness in a cave, away from entrances, is absolute.
Animals keep snow out of there eyes by blinking :)
The animals close their eyes at night because at night humans show their inner beauty and the animals get digusted and close their eyes .
"Do people and animals have the same eyes?" Animals can have the same eyes as a human being. But most of them don't have the eyes of an human being.
u probably need to eyes so it is easier to see. close one eye. u cant see like, the other half (get it?) and animals like deer, antelopes etc. need two eyes to watch for predators when they eat :)
Birds avoid animals with large eyes on the front of their heads because they see them as predators. This is frightening to the bird, so they stay away. Animals with smaller eyes to the side, rather than front, are not thought of as predators by the birds.
crabs have eyes on stalks :)
All nocturnal animals do not have beady eyes. An example of a nocturnal animal that does not have beady eyes is the cat.
