Most tetrapods -- including pre-human mammals -- originated in water and have since evolved to function on land. As such, substantial anatomical chance has occurred.

What is phylogenetic constraint?
Phylogenetic Constraint is like a basic body plan. It can be modified (what evolution does) but it can't be fully changed. Vestigial features (things like the human appendix which is a remnant of our ancestors, but is no longer used) provide evidence of common ancestry and phylogenetic constraint. :)
Do only humans have prefrontal cortex?
All primates have a prefrontal cortex similar to humans. Other animals may have them in different forms, see the below excerpt. "The lack of a single anatomical or functional definition of 'prefrontal cortex' has led to different and, in some respects, controversial views on the existence of a prefrontal cortex in non-primate mammals, in particular in rats... ... We will argue that rats have a functionally divided prefrontal cortex that includes not only features of the medial and orbital areas in primates, but also some features of the primate dorsolateral prefrontal cortex."
Why do they break the body into sysems when discusing the body?
There are so many different body systems that is it easier to understand and to study if them if the body's anatomy and physiology is broken into pieces. Usually the less complex is studied first. The basic ideas can be a start for the addition of more difficult concepts. You can not build a house from the roof down.
How are anatomical features used to classify organisms?
These features were used to classify organisms before the development of DNA analysis. This way, scientists were able to look at certain morphological traits to classify the organism and then correlate them to their closest relatives. For example. Although bats are a lot like birds, certain morphological traits allow them to be classified as something other than birds. i.e. they are mammals - they have similar bone structure to most mammals In this regard, it is based traits other than their wings that they are classified as mammals, and not birds.
