The correct answer is: a) Hand axes.
Hand axes are a type of stone tool that was used by early humans during the Lower Paleolithic period. They are typically made of flint or other hard stone and are characterized by their bifacial (two-sided) flaking. Hand axes were used for a variety of purposes, including hunting, butchering, and woodworking.
Microliths are small, flaked stone tools that were used by early humans during the Upper Paleolithic period. They are typically less than 2 centimeters in length and are often made of flint or other hard stone. Microliths were used for a variety of purposes, including hunting, fishing, and woodworking.
Blades are long, thin flakes of stone that were used by early humans during the Middle Paleolithic period. They are typically made of flint or other hard stone and are often used to make other tools, such as knives and scrapers.
Harpoons are pointed, barbed spears that were used by early humans for hunting fish and other aquatic animals. They are typically made of wood, bone, or ivory and are often tipped with stone or metal points.
The Lower Paleolithic period is the earliest period of the Paleolithic or Old Stone Age. It is characterized by the use of simple stone tools, such as hand axes. The Lower Paleolithic period lasted from about 2.5 million years ago to about 200,000 years ago.
The Upper Paleolithic period is the middle period of the Paleolithic or Old Stone Age. It is characterized by the use of more sophisticated stone tools, such as microliths. The Upper Paleolithic period lasted from about 40,000 years ago to about 10,000 years ago.
The Middle Paleolithic period is the later period of the Paleolithic or Old Stone Age. It is characterized by the use of blades and other more sophisticated stone tools. The Middle Paleolithic period lasted from about 200,000 years ago to about 40,000 years ago.
