This is a myth. Rhino's can walk backwards. The only animals that can't, are Emus and Kangaroos.
A question that cannot possibly be answered. How long will it take to walk all of Earth? You can go for years (decades) and still have not been everywhere. Walking on Mars would definitely take even more time as the movements there will be much slower. Present Mars exploration scenarios (for a visit by humans) provide for a stay of a couple of days only.
humans walk on their metatarsals. Metatarsals are the center area of the foot, metacarpals are the palms(on the hands).

The emu is said to be unable to walk backwards.
Yes. There is nothing, physiologically or structurally, to prevent a platypus from walking backwards.
Brown bears really can't walk backwards. These brown bears do not feel reassured, comfortable or even safe when walking backwards.
Yes they are the only ones capable of walking backwards and survive being cooked in a microwave
Whether or not emus can or cannot walk backwards has never been definitively proven, as the phenomenon of them walking backwards has been neither observed nor recorded. It is believed that the joints in their knees make it impossible for them to walk backwards.
no animal can walk backwards, they don't have legs!!
Kangaroos have not been observed walking backwards.
No emu has ever been observed walking backwards. Whether or not they can remains an issue of debate.
Emus are not believed to be able to walk backwards. There have been no documented instances of emus walking backwards, and no evidence exists to suggest they can. One theory is that the joints in their knees make it impossible for them to walk backwards.
The average walking pace in feet per second for humans is about 4 feet. Some may walk faster or slower, and may have a longer or shorter stride.
There is not a superstition that says if you walk backwards through a door that you will trick the devil. There is one that says walking backwards through a door will make you forget things.
It is believed that emus cannot walk backwards, as no evidence exists to the contrary. That is why, together with the kangaroo (which also cannot walk backwards), the emu is on the Australian coat-of-arms, symbolising progression forwards. Whether or not emus can or cannot walk backwards has never been definitively proven, as the phenomenon of them walking backwards has been neither observed nor recorded. It is believed that the joints in their knees make it impossible for them to walk backwards.
