Final answer:
Homo erectus from the early Pleistocene used fire, cooked and ate meat, had a larger size and brain compared to earlier hominins, and adapted to colder climates.
Step-by-step explanation:
Homo erectus, also known as the Upright Man, appeared around 1.8 million years ago. Fossils of H. erectus have been found in India, China, Java, and Europe. Some examples of H. erectus from the early Pleistocene include the fossils found at Zhoukoudian, China, which provide evidence of using fire, cooking and eating meat. H. erectus was also larger in size compared to earlier hominins, had a more similar brain size to modern humans, and had adapted to colder climates with their downward-facing nostrils.
