Agriculture provided a stable food source and encouraged population growth, which allowed for the development of settlements which would become towns and later cities. However, the settled diet wasn't as varied as a hunter-gatherer diet and the dense settlements allowed diseases to spread easily. As populations and wealth grew in settled communities, hierarchies and classes were established. Warfare also intensified.
Humans first successfully migrated into the west of Asia about 70,000 years ago, and by 50,000 years ago had migrated to Eastern Asia and Australia. About 40,000 years ago, humans first migrated to Europe. The last areas to be reached were the Americas, through the Beringia land bridge about 15,000 years ago. As they migrated, humans impacted the environment and become the top predators. Many scientists believe that humans were a main factor for the extinction of Pleistocene megafauna.

By controlling fire, early humans were able to eat a more varied, nutritious diet.
The discovery of fire by the early humans which dates back to some 2 million years ago helped to improve their diet as they could then cook their meals and preserve them. Prior to the discovery of fire by the early men, they ate fruits, nuts, and seeds. But the discovery and control of fire helped them to consume foods rich in calories.
They could now roast the animals they got from hunting and preserve them for later. The control of fire also helped them to keep warm in their caves.
Therefore, instead of consuming only fresh foods, they could now also cook meals rich in fats, oils, and protein.
Summarily, the control of fire helped early humans to eat a more varied and nutritious diet.
