Soup Making May Be Older Than We'd Thought

Soup comes in many variations - chicken noodle, creamy tomato, potato and leek, to name a few. But through much of human history, soup was much simpler, requiring nothing more than boiling a haunch of meat or other chunk of food in water to create a warm, nourishing broth.

Most sources state that soup making did not become commonplace until somewhere between 5,000 and 9,000 years ago. That's probably wrong - by at least 15,000 years. So who concocted that first bowl of soup?
