A fun game started with this post..

This one is tough, if knees were backward, first of all, we’d be goofy looking beings. I’m not sure that would give us any biomechanical advantage at all.  So thank goodness God got it right by making our knees work like they do. However I’m getting off topic. If our knees bent the other way I would have to say with a guess that we’d sit in some sort of kneeling position.  In fact after thousands of years of human evolution, I’m pretty sure our knees would be much bigger, and stronger, to hold the extra weight of just sitting.  I also think our butts would be smaller cause they were not have to be the cushion for the seats anymore. I wonder if big booty guys would check out big knee girls then?
