Final answer:
Ancient humans in cold environments relied on tools such as spears for hunting and bone needles for making warm clothing. They constructed shelters from bones and hides to protect against the elements, and the shared challenge of survival led to strong community bonds.
Step-by-step explanation:
Tools for Ancient Humans in Cold Environments
Ancient humans migrating into cold environments would have utilized several tools for their survival. Notably, they may have employed spears for hunting large game, which was crucial for food as well as for materials that could be used in making shelter and clothing. In addition to this, harnessing bone and wood for making advanced tools such as harpoons for marine hunting would have been important.
Warm clothing and shelters were essential for protection against the harsh elements. Clothing would likely have been created from the hides of animals, using bone needles for sewing, whereas shelters could be made from bones, such as mammoth bones, and covered with animal hides or other available materials. The development of pottery would have also been advantageous for cooking and storage, however, it is more associated with settled societies postdating the hunter-gatherer era.
These tools not only aided in the physical survival of early humans but also played a role in the social structure and community bonding. In cold climates, successful hunting required teamwork, and sharing the spoils would reinforce reliance on the group. The shared need to survive the cold made cooperation and tool innovation central to the human experience in these environments.
