OK, imagine you are a cow. Now walking up, most of the weight of your body is down and back, and your knees bend helping you push yourself up. Now walking down, most of the weight is on your front legs, and your knees bend and point down the stairs, and with all the weight and the very real possibility that you could tumble down frontwards, you just won't do it.
But, you say, I see cows go down hills all the time in John Wayne movies.
Yes, they do down hills, but the sides of the hills are not broken up by STEPS that cause you to , as it were, go on faith that the next step is short enough that you won't trip.
Think of it as you woujld a child, kids will first start to climb UP steps, but getting them to go down takes a lot of patience and care by the parents, till they learn to walk down.
Not if it's too steep and the steps too narrow for them to go down.
You can lead a cow upstairs but not downstairs
yes they can, but they cannot walk down them.
You can pull an elephant upstairs, bud it won't know how to come down by itself.
