Cultural transmission: Cultural transmission is the process through which knowledge, beliefs, skills, and behaviors are passed from one generation to the next through social learning and communication. This concept emphasizes the importance of social interactions in shaping individual and collective cultural practices, often leading to innovation and adaptation in response to environmental challenges. Cultural transmission plays a crucial role in understanding the development of tool use, technology, and language among early humans.
Division of labor: Division of labor refers to the allocation of different tasks and roles among individuals or groups within a society or community, allowing for specialization in skills and efficiency in task completion. This concept is crucial for understanding social organization and collaboration, particularly in relation to the development and use of tools, as well as the advancement of cultural practices and cognitive abilities. By enabling individuals to focus on specific tasks, division of labor has implications for technological innovation and social structures.
Expanded diet: An expanded diet refers to the broadening of food sources that early humans accessed, incorporating a variety of plants and animal proteins into their meals. This shift not only improved nutritional intake but also required more complex cognitive skills for foraging and tool-making, enhancing social interactions and cultural developments.
Fine motor skills: Fine motor skills refer to the ability to perform precise movements using small muscle groups, particularly in the hands and fingers. These skills are crucial for tasks that require hand-eye coordination and dexterity, which are essential for early tool use in human evolution.
