I beg to differ. Lets use a dog for example.
The 'backwards' part of the rear legs you speak of is actually the 'heel' and the dog walks on his toes. The 'thigh' or femur is very short relative
to human limbs, which makes the knee rest by the abdomen. The fibula or 'shin' below that, and the patella or 'knee-cap' faces forward. Notice how
the tarsus or 'heel' is lifted off the ground.
Compare the anatomy to that of a human:
Try to imagine having the dog jump up on you, and standing on the rear two legs. Their rear limbs are built exactly like ours, just in different
proportions. With the dog jumping up on your chest, he would be standing on his tippie toes.
Edit: I mistakenly said that birds had reverse limbs, but even birds legs are built the same as ours. The 'backwards' bend in a birds leg is actually
the heel as well, it seems the thigh is hidden in all those feathers!
I hope all of this made sense, sometimes it can be hard to translate an image in the mind into words on the page.
