I want to know the answer to the following question:
What did a dog's good hearing help humans with?
All the background I'm provided with is that "Dogs may have provided warmth, as referred to in the Australian Aboriginal expression "three dog night" (an exceptionally cold night), and they would have alerted the camp to the presence of predators or strangers, using their acute hearing to provide an early warning.". Is that enough to answer the question?
Answer: yes
