Prehistoric technology

technology Maturity 9-11 Next article →

Prehistoric technology refers to the tools and methods used before humans began keeping written records. History relies on written accounts to study the past. Prehistory includes everything that happened before those first records existed. This era began roughly 2.5 million years ago. It started when the earliest hominids began using stone tools. These tools were first used to hunt for food. Later, they were used to help cook food.

Technology evolved because of changes in the human brain. The development of Homo sapiens brought behavioral modernity. This included abstract reasoning, language, and complex problem-solving.

The Stone Age was a vast period defined by the use of stone. Humans made implements with sharp edges, points, or percussion surfaces. This period lasted about 2.5 million years. It began with early hominids and continued through the Pleistocene era. The Stone Age largely ended between 6000 and 2000 BCE. This change happened because of the advent of metalworking. For most of this time, people lived as hunter-gatherers. They traveled to hunt game and gather wild plants. Their technology changed very little for millions of years.

The Lower Paleolithic was the earliest subdivision of the Stone Age. It lasted from 2.5 million years ago until about 300,000 years ago. This era included Oldowan and Acheulean lithic technologies. Oldowan tools, also called "mode 1," were created by Homo habilis. This species is often called "handy man." Later, Homo ergaster developed more sophisticated tools. They created the first Acheulean bifacial axes. Homo erectus lived in West Asia and Africa. They were likely the first to hunt in coordinated groups. They also used complex tools and cared for the weak.

As time passed, new species developed unique ways of using technology. Homo antecessor lived in Northern Europe 1.2 million years ago. Homo heidelbergensis lived between 600,000 and 400,000 years ago. They used tools similar to the Acheulean style. Some evidence suggests Homo erectus controlled fire 1.5 million years ago. In Israel, sites suggest humans could light fires 690,000 years ago. The Middle Paleolithic occurred in Europe and the Near East. During this time, Neanderthals used Mousterian Stone tools. These tools included smaller knives and scrapers. Neanderthals also buried their dead in shallow graves. They often placed stone tools and bones with the bodies.

Homo sapiens appeared in Africa about 200,000 years ago. Our species has a more complex brain structure. This allowed for better coordination when manipulating objects. Around 50,000 years ago, humans reached full behavioral modernity. This led to the Upper Paleolithic Revolution. During this time, people created Aurignacian tools. These included stone blades, antler tools, and bone tools. Humans also began making clothing. Sewing needles have been found from about 40,000 years ago. Some evidence suggests humans wore clothing 190,000 years ago. They even used poisoned weapons for hunting. In South Africa, arrowheads from 60,000 years ago show toxic plant traces.

The Mesolithic period was a transitional era. It began with the Holocene warm period about 11,660 years ago. This period ended when farming was introduced in the Neolithic. Climate changes forced humans to adapt to new environments. They began using microliths, which are very small stone tools. These small blades served as tips or barbs for arrows. In southwest Germany, archaeologists found trapezoidal stone tips. They also found large barbed antler harpoons. These tools show how humans adapted to hunt different prey. This period bridged the gap between nomadic hunting and settled farming.

The Neolithic Revolution changed human life forever. This was the first agricultural revolution. It happened independently in six locations worldwide. This occurred between 10,000 and 7,000 years before present. Humans shifted from nomadic lifestyles to settled ones. They began living in permanent homes. They domesticated animals and farmed the land. This led to more sophisticated and varied tools. Agriculture allowed for significant technological advancements. It moved humanity away from the constant movement of hunter-gatherers. This shift created the foundation for settled civilization.
