It is interesting that God did not make Eve in the same manner as He made Adam. God breathed His life into Adam, and then took a part of this life and somehow expanded it to form Eve.
Here is a question: do men and women have the same number of ribs? Of course they do! Even though Adam lost one of his ribs, his genes were not altered and the children of Adam and Eve all had the proper number of ribs. Acquired characteristics are not inherited.
