Their findings were based on studies of ancient teeth which tend to be well preserved. Archaeologists have been able to examine the teeth of not only our ancient ancestors, but also people who lived more recently, and who followed a hunter gatherer diet such as Kalahari Bushmen and the aboriginals. Around 13,000 years ago these hunter gatherers began to become farmers, and as a result food became much softer and didn’t need to be chewed so much.
