Difference between frog and primates...?

Question

How are the frog hip and leg alignment different from hip and leg alignment in the primate and why?

Answer 1

The legs of the frog go out to the sides. Primates go underneath, an improvement that was started in the more advanced reptiles.

Answer 2

Peter is right except for the "improvement" part. For frogs having legs out to the side is perfect for them and their environment.

I wish people would stop thinking the primate "alignment" of everything is necessarily superior to other options. It may be different but not necessarily better in all circumstances.
