Final answer:
The tool technology associated with the first H. erectus/ergaster out of Africa is the Acheulean industry. The diet of H. erectus/ergaster consisted of a variety of foods including meat and plant-based foods.
Step-by-step explanation:
The tool technology associated with the first H. erectus/ergaster out of Africa is the Acheulean industry. These tools, which are more complex than the previous Oldowan stone tools, have been found in Africa, Europe, and the Middle East. However, they are rarely found in Asia. It is unclear whether this is because the Acheulean industry had not yet been developed when H. erectus migrated to Asia or because certain plants needed to make these tools were not available in Asia.
The diet of H. erectus/ergaster consisted of a variety of foods. There is evidence that they hunted, cooked, and ate meat. Fossil remains suggest that they also consumed plants, including fruits, seeds, roots, and tubers. Recent analysis of a H. ergaster specimen from Kenya indicates that they may have been consuming carnivore liver, which is high in Vitamin A. Overall, their diet likely consisted of a mixture of plant-based and animal-based foods.
