My first thoughts too. Why does everything in psychology/social has to be tied to evolution these days? Once upon a time, you did it because someone told you too. Then, some god. Later, because you're of a certain class. Today, we're doing it because it helps the "evolution". This is nice, if you know why the evolution does what it does. Which is turtle all the way down. Shit, something helps us to last longer as a species? It's the answer. If we know how it helps us. Heck, I'll throw an evolutionary bias into this research. Why should I help another male? It's my desire that he fails so I can own the offspring-maker. (yes, I'm aware of some studies that show cooperation is better for the group. WITH FISHES). "For evolutionary reasons" is the new thing on social studies. 3pt14159's comment is spot on http://news.ycombinator.com/item?id=700571 http://news.ycombinator.com/item?id=700571 this study has too many random variables to have any credulity.
