The Evolution of Dungeons and Dragons over the Editions

1st Edition Monster Manual

Grimm and I were chatting about D&D on Twitter recently and it got me thinking about the evolution of the game Dungeons and Dragons.  I had recently commented to a friend that D&D always felt like it was designed around combat and the RPG parts were tacked on later.  I feel like this is an easy argument to make considering it's birth from the Chainmail system.

From Advanced Dungeons and Dragons and the most recent 5th Edition - what's changed?

Well, quite a lot and yet not much.
