Which subjects need to be added to current evolutionary theory to create a new extended synthesis?

Here's a list of subjects that have been proposed as extensions to the so-called "Modern Synthesis" of evolution. Some of them are radical changes and others are more subtle.

I'm not going to explain all of them because that would take many posts and a lot of time. Besides, most of them have been openly debated on numerous blogs over the past decade or so.

Choose the one(s) that you think are the most important.
