"As populações da Idade da Pedra tinham vidas mais saudáveis do que a maior parte do povo que surgiu imediatamente depois delas. Quanto a facilidades, como a boa alimentação, os divertimentos e os prazeres estéticos, os primitivos caçadores e recolectores de plantas gozavam de luxos que só os mais ricos dos nossos dias podem gozar" - Marvin Harris (1927-2001).
