TED: Nicolas Perony: Puppies! Now that I’ve got your attention, complexity theory - Nicolas Perony (2013)

Summary: Animal behavior isn't complicated, but it is complex. Nicolas Perony studies how individual animals -- be they Scottish Terriers, bats or meerkats -- follow simple rules that, collectively, create larger patterns of behavior. And how this complexity born of simplicity can help them adapt to new circumstances, as they arise.
