Ask AI: Expain how biolological and intellectual changes of early man help him to exploit environment for survival in stone age

During the Stone Age, early humans evolved both biologically and intellectually, which allowed them to better exploit their environment for survival. Here are some key ways that these changes took place: 1. Bipedalism: Early humans developed the ability to walk on two legs instead of four, which is known as bipedalism. This biological change allowed them to cover greater distances while searching for food and resources. Bipedalism also freed up their hands, enabling them to use tools, carry objects, and better manipulate their surroundings. 2. Increased brain size: Over time, early human brain size increased significantly, leading to improved cognitive abilities. A larger brain enabled early humans to develop better problem-solving skills, communication, and abstract thinking. These intellectual changes allowed early humans to create more sophisticated tools, plan more effectively, and share knowledge across generations. 3. Development of language: As the human brain evolved, so did our capacity for complex communication. Early humans developed language, which allowed them to communicate ideas, plans, and emotions. Language facilitated cooperation and collaboration, enabling early humans to work together in hunting, gathering, and resource management. This greatly improved their ability to exploit their environment for survival. 4. Tool-making: The intellectual and biological changes in early humans led to the development of a wide range of tools during the Stone Age. Early humans made sharp-edged tools from stones, such as hand axes and spearheads, that enabled them to process food and defend themselves against predators more effectively. The development of tools also allowed early humans to hunt larger, more nutritious animals, which further contributed to their survival. 5. Control of fire: One of the most significant intellectual achievements of early man was the control and use of fire. Fire provided light, warmth, and protection from predators, allowing early humans to expand their activities into the night and occupy more diverse environments. In addition, fire facilitated the cooking of food, which made it more digestible and nutritious, contributing to survival and overall health. 6. Social organization: As early humans evolved, so did their social organizations. With increased cognitive abilities, early humans began to form more complex social structures based on kinship, cooperation, and division of labor. These social organizations increased the capacity for group problem-solving, resource allocation, and communal care, which all ultimately contributed to their ability to exploit their environment for survival during the Stone Age.
