Overall a very good snippet. I found this to be one of the most interesting topics in class, so I think it is certainly worth emphasizing. I think you chose a very good part of the article to modify, as that particular section looks like it could use a lot of work. I notice however in the in-group favoritism article there is a section that talks about versus out-group negativity. Maybe it would be possible to explain that perspective from a biological standpoint as well--instead of just how oxytocin benefits in-group favoritism, do we know anything about what causes the hostility? Additionally, the last paragraph lacks a source and I think a source would definitely be valuable, as you are referencing a particular Dutch study. For the rest of the article, however, the citations look good and the information is interesting. Hfbaker (talk) 04:37, 7 November 2016 (UTC)
