No problem. From that post, it looks like we have exhausted some topics, agreed on others (from the end of that post -#270), and the main topic we'll get back to is about how morality can develop (below).
I don't remember how many were direct links, and how many were links to pages that had more links. However, I did notice that the bibliography to the Moral Animal is available online, and that has pages and pages of references. Of course, many of those are not what you are looking for, but many are. If you really want to look into the extensive work that has been done, that's a list that will take you years to investigate.
To access that list, go to the link below, click on "index", then page up above the index, and you'll be in the bibliography.
