This calorie-rich diet likely contributed to the development of our larger brains, which are energy-demanding organs that require substantial nutritional support.

In addition to providing a nutritious diet, fire also offered protection and warmth to early humans. The ability to create and control fire allowed our ancestors to ward off predators and thrive in different environments, including colder regions. Fire provided a source of warmth, which was essential for survival, particularly during harsh winters. By huddling around a campfire, early humans were able to stay warm, ensuring their survival in challenging conditions.

Beyond its practical benefits, fire also had a profound social impact on early humans. The gathering of individuals around a fire fostered social interactions and the development of communal activities. As humans gathered to share warmth and food, they likely engaged in storytelling, exchanged knowledge, and formed social bonds. These social interactions around the fire may have played a crucial role in the development of our social nature, shaping us into the cooperative and collaborative beings we are today.
