Which invention helped early humans move outside of Africa
The invention that helped early humans move outside of Africa is believed to be the production and use of simple tools, particularly the hand axe. These tools were likely used by erectus, an early human species, to hunt, butcher animals, and gather food. The hand axe enabled early humans to adapt to different environments and survive in various climates, allowing them to eventually expand beyond Africa into other parts of the world.
The invention that helped early humans move outside of Africa is believed to be the development of stone tools. These tools, which were first created around 2.6 million years ago, allowed early humans to better adapt to their environment and engage in activities such as hunting, gathering, and ultimately, expanding their territories beyond Africa. By enabling them to hunt more efficiently and gain access to new food sources, stone tools played a crucial role in the migration of early humans out of Africa and their ability to survive in different environments.
One of the important inventions that helped early humans move out of Africa is the hand axe. The hand axe is a multipurpose tool that was used by early humans around 1.5 million years ago. It was crafted by shaping a stone into a sharp-edged cutting tool.
To understand how the hand axe helped early humans move outside of Africa, let's explore the context. During the early Stone Age, also known as the Paleolithic period, our ancestors were primarily confined to Africa. However, around 1.8 million years ago, there was a major climatic change with the onset of an ice age. As a result, the climate became harsher, and certain areas of Africa, particularly the northern regions, experienced drier conditions.
In response to this environmental challenge, early humans had to adapt and find new resources to survive. This is where the hand axe played a crucial role.
Early humans used the hand axe as a versatile tool. It helped them in various activities such as hunting, cutting, digging, and butchering animals. The sharp edge of the hand axe made it easier for them to butcher animals for meat and skin, which provided a valuable source of food and clothing.
The hand axe also played a vital role in early humans' ability to control fire. By using the hand axe to strike stones together and create sparks, they could start fires. Fire had numerous benefits, including providing warmth, cooking food, and offering protection against predators.
With the hand axe as an essential tool, early humans were better equipped to survive and adapt to different environments. It allowed them to exploit new resources, including those outside of Africa. As they migrated to different regions in search of food, water, and suitable living conditions, the hand axe proved indispensable.
Therefore, the invention of the hand axe enabled early humans to move beyond Africa and explore new territories, contributing to their success as a species.
