15. Social development

When Homo heidelbergensis existed in 300,000 BC, their species had well-developed brains because of the meat added to their diet. This was one of the key reasons of how they figured out many of their ideas, which were key to their survival as well as that they helped to socially develop their species. Childcare was (handled RB) by having the females take care of the young and collect vegetables and easy-access food, while the males were out hunting. This leads to another idea Homo heidelbergensis established which was the moving around in large groups. This was an extremely useful strategy because when species travel in groups, it is less likely for other animals to attack them when the animal feels outnumbered and frightened.

These leading approaches on improving lifestyle are the reasons why Homo heidelbergensis evolved by 300,000 years ago into Neanderthals and archaic humans. Modern humans began to slowly develop about 100,000 years ago. No Homo heidelbergensis remained by 28,000 years ago. From the little communication and knowledge of Homo heidelbergensis, to the wide range of vocabulary and comprehension of the world that we have today, the different species of apes developed tremendously over time and created strategies that proved to be beneficial to their social development.
