Early Human Innovation: The Stone Age Foundation
The Stone Age was our first major technological era, lasting about 3.3 million years. Finds in Kenya’s Lake Turkana give us a glimpse into these early times.
Our ancestors, like Australopithecus, made basic tools that changed our lives. These early steps in prehistoric technology started tool making and use.
Millions of years ago, people made sharp stone flakes and hammer stones. These show they were made on purpose, not by accident.
Basic Toolmaking and Survival Technologies
Early stone age tools helped with survival. Sharp flakes helped process food, while hammer stones cracked bones and nuts.
Tool making followed patterns in different places. The Oldowan industry, named after Tanzania’s Olduvai Gorge, was the first standardised tool making.
These tools gave many survival benefits:
- They helped get and prepare food better
- They made defending against predators easier
- They made using resources more efficient
- They helped people work together using tools
Creating basic tools helped us develop important skills. These skills were the base for all future tech progress. It shows how simple ideas can lead to big changes.
Agricultural Revolution: Foundation of Civilisation
The move from nomadic hunting to settled farming was a huge change for humans. This period, known as the Neolithic revolution, started modern society as we know it today.
Domestication of Plants and Animals
About 12,000 years ago, humans started growing wild plants and taming animals. This change from foraging to farming led to more food. This food helped support bigger, permanent homes.
Domestication needed careful watching and selective breeding. Early farmers picked the best plants and animals to manage.
“The agricultural revolution allowed humans to become masters of their food supply, not just servants.”
This new agricultural technology helped communities stay in one place. Having a steady food supply meant less searching for food. This was a big change from hunter-gatherer societies.
Irrigation Systems and Early Engineering
By 6000 BCE, places like Mesopotamia and Egypt had complex irrigation systems. These systems brought water to crops, helping them grow in dry areas.
Early engineers built canals, dams, and places to store water. These projects needed great planning and teamwork. They showed advanced social organisation.
The table below shows key irrigation developments during this period:
| Region | Time Period | Irrigation Innovation | Impact |
|---|---|---|---|
| Mesopotamia | 6000 BCE | Canals from Tigris/Euphrates | Enabled farming in dry seasons |
| Egypt | 5500 BCE | Basin irrigation from Nile | Stabilised agricultural output |
| Indus Valley | 5000 BCE | Gravity-fed channels | Supported large populations |
These engineering feats turned poor land into fertile areas. Food security soared in early civilisations.
The Invention of the Wheel and Its Impact
Around 3500 BCE, the invention of the wheel changed everything. It first appeared in Mesopotamia, likely for pottery. Later, it was used for vehicles.
The wheel quickly spread through trade networks. It made moving goods, people, and ideas easier than before.
Its effects were huge:
- Trade improved with wheeled carts
- Agriculture got better with wheeled ploughs
- Building techniques improved with pulleys
- Military used chariots
This shows how simple inventions can lead to big changes. The wheel is one of humanity’s most lasting inventions.
The Neolithic revolution changed human life a lot. It allowed for settled communities, specialisation, complex societies, and knowledge growth. This set the stage for future civilisations.
