Quizplus · Accepted Answer

The shift from eating primarily fruits and leaves to eating seeds and nuts in hominins is associated with smaller incisors and canines (for biting and cutting), larger molars (for grinding hard foods), and thicker enamel (to withstand the wear from harder foods). All these adaptations are necessary for processing the tougher, more abrasive diet that includes seeds and nuts.
