Actually, if you believe there is a distinct difference between man and animal, in that God created man (and woman) in his own image, then yes, the Bible is very explicit in that area. However, if you believe man evolved, then there is no distinct difference between man and animal and an argument for the soul cannot be found in the Bible.
As for Cain and Able, they weren't Adam and Eve's only children. They probably "married" their sisters.
