A cut-throat case of evolutionary backstabbing in the Peruvian rainforest

The Peruvian Amazon is teeming with life. For the flora and fauna that make it their home, this means that fierce competition is part of the bargain. This short from KQED’s science documentary series Deep Look investigates the remarkable measures species will take to get an edge in contested evolutionary battlegrounds, examining the curious case of big-headed ants, which have betrayed a longtime evolutionary ally, Inga trees, for a sweeter deal with a caterpillar.
