Timeline of recent research into positive selection

Experimented with a timeline format to summarise key developments in the debate regarding the importance of positive selection, particularly in human evolution, and how to detect it. If anyone wants to add entries to help the timeline grow (which would be great) I believe you can do so by creating a free Dipity account and viewing the timeline through their website.
