ELI5: Why are some letters basically the same capital and lowercase (O, W, P) and some vastly different (G, E, Q)?

Our alphabet is derived from the Latin alphabet.  The Upper case is essential the Latin.  The lower case alphabet is derived from the Latin through an intermediate font called Carolinian minuscule.  This is a smaller font derived from the Latin alphabet designed to be easy to read and quick to write.  Changes were made to some letters to make it easier to distinquish them.
