在300到200万年前，我们的东非祖先变成了杂食性动物。一种以素食为主的两足灵长类动物改变了饮食策略，开始吃来自大型哺乳动物身体的动物性食物、肉类和脂肪，一开始就形成了一种拾取食物的行为。这只有可能归功于一种超自然进化的发展，即制造石器、切片来切割和肢解身体的文化技术，以及用来打断骨头和提取骨髓内容物的敲击工具。这些最早的岩屑非常原始和原始，以鹅卵石、岩芯和薄片为主，对应于命名为Oldowan或Model1的岩块。
Between 3 and 2 million years ago, our eastern African ancestors became omnivorous. A biped primate with mostly vegetarian eating strategy changed and started to eat animal food, meat and fat coming from the carcasses of large mammals, developing at the beginning a scavenging behavior. This was only possible thanks to the development of one extrasomatic evolution, the cultural technology making lithic artifacts, flakes to cut and dismember the carcasses and percussion tools to break the bones and extract the marrow content. These earliest lithics were very primitive and rudimentary, dominated by pebbles, cores and flakes, corresponding to the named Oldowan or Mode 1.
