Homo Heidelbergensis had short, wide bodies, which is why they were able to adapt to the colder climates that they were the first to live in. They were also the first to hunt large animals routinely, and to build simple shelters using wood and rock. They were able to hunt because they used wooden spears and could use fires very well. They lived about 700,000 to 200,000 years ago. I can infer based on the skull and the video that they were definitely starting to look a lot more human, but still had a long way to go. I can also infer only based on the video that Homo Heidelbergensis really started to spread out a lot, to places like India and China, and adapted well. They migrated, like Homo Erectus, North, and then went East and West, just above Africa.
