Inspired by a comic by SMBC's Zach Weiner, BAHFest is "a celebration of well-researched, logically explained, and clearly wrong evolutionary theories." Winners are awarded a sculpture of Darwin shrugging skeptically.


Last year's was the second annual BAHFest. Two more festivals are scheduled for 2015 – one for the East Coast and one for the West. Watch the winning presentation from 2013 – in which MIT researcher Tomer Ullman argues that humanity's early ancestors harnessed the "natural adrenaline boost" brought on by the sound of wailing babies by wearing them into battle – here.
