It's widely accepted that our ancestors were cooking 300,000 years ago, but evidence found at Wonderwerk Cave in South Africa suggests we may have started using fire to heat our food much earlier than that. Archaeologists Candice Koopowitz and David Morris discuss the findings and explain what researchers need to look for in order to find out if we were cooking a million years ago.
