It seems obvious to me that this would have started when some intelligent penguins realized that they could hunt more efficiently if they did it in packs, and they continue to use their intelligence to organize the hunt. But that doesn’t stop individuals from hunting too. What is the difference between this and human behaviour? Of course generations of penguins will learn from earlier generations, just as humans do, but in both cases it has to be penguin/human intelligence that starts things off.
