3000 years ago, city states were already formed in developed parts of the world, in Mesopotamia, Egypt, east of Europe, and Far East like in China. Therefore, people used to be either village/city setters, or nomads (or hunters) with no fixed location.
4,000 years ago, climate change caused massive civilization collapse. Ancient Egypt and Mesopotamia may be the best known of the first great urban cultures, but the largest was the Indus or Harappan civilization.
End of the Stone AgeThe Chalcolithic by convention is the initial period of the Bronze Age. The Bronze Age was followed by the Iron Age. The transition out of the Stone Age occurred between 6000 and 2500 BCE for much of humanity living in North Africa and Eurasia.
Our current archaeological three-age system – Stone Age, Bronze Age, Iron Age – ends in the same place, and suggests that we haven't yet left the iron age.
Actually, 4000 years ago was 1984 BCE (as of 2017 when the question was first asked; today, in 2018, 4000 years ago would be 1983 BCE).
The Stone Age lasted from 30,000 BCE to about 3,000 BCE and is named after the main technological tool developed at that time: stone. It ended with the advent of the Bronze Age and Iron Age .
Around 4,000 years ago the Bronze Age came to Britain. This was the crucial period that linked the Stone Age with the Iron Age, and during which it seems new people came in from continental Europe.
Divided into three periods: Paleolithic (or Old Stone Age), Mesolithic (or Middle Stone Age), and Neolithic (or New Stone Age), this era is marked by the use of tools by our early human ancestors (who evolved around 300,000 B.C.) and the eventual transformation from a culture of hunting and gathering to farming and
The Ages
| Age | Time | Period Name |
|---|
| Stone Age | - 3.000 BC | Neolithic |
| Bronze Age | 6.000 - 2.000 | Copper Age |
| 3.000 BC - 500 AD | Bronze Age |
| Iron Age | 1.000 BC - now | Iron Age |
Neolithic, also called New Stone Age, final stage of cultural evolution or technological development among prehistoric humans. The Neolithic followed the Paleolithic Period, or age of chipped-stone tools, and preceded the Bronze Age, or early period of metal tools.
The period of human culture preliminary to the Bronze Age, characterized by the use of copper and stone tools.
Chronology of Chalcolithic SettlementThe first metal age of India is called Chalcolithic Age which saw the use of copper along with stone. It was also called Stone-Copper Age. Along with the use of copper and stone these people also used low grade bronze to make tools and weapons.
The Neolithic period covers the era 3900-1700 BC. The hunting people in Denmark had long had contact with the farming societies in central Europe, but only around 3900 BC the hunters began to till the land and keep animals.
The discovery that copper could also be obtained by heating Blue Stones or minerals (primarily copper sulfide ores) occurred between 4000 - 3000 BC. The extraction of Copper from Copper Sulfide Ores provided Man with another, more abundant source of copper. Hence, Metallurgy was born.
Copper offered people a great advantage over stone. The metal was far more durable than the stone tools they had previously used, which could shatter if hit too hard. Metal tools could also hold a sharper edge. Around 4500 BCE, someone discovered that copper hardened if it was melted down and allowed to resolidify.
Copper FindingsAlthough various copper tools and decorative items dating back as early as 9000 BCE have been discovered, archaeological evidence suggests that it was the early Mesopotamians who, around 5000 to 6000 years ago, were the first to fully harness the ability to extract and work with copper.
The Copper Age was a time period between the Neolithic and the Bronze Age. In the Bronze Age, people added tin to copper to make bronze, an alloy which is much harder than either tin or copper. During the Copper Age, this fact became known, but was not much used because tin was scarce.
Although iron and lead were in use by the era of the ancient Romans, copper, bronze, and brass (an alloy of copper and zinc) were used by the Romans for coins, aspects of architecture such as doors, and some parts of their extensive plumbing system (although pipes were made of lead).
The Bronze Age is the time period when people made tools from an alloy (a mixture of metals) called bronze. Bronze is a mixture of mainly copper and tin: usually nine parts copper to one part tin. For example, bronze was first used in Mesopotamia around 3300 BC.
Our current era is the Cenozoic, which is itself broken down into three periods. We live in the most recent period, the Quaternary, which is then broken down into two epochs: the current Holocene, and the previous Pleistocene, which ended 11,700 years ago.
The Precambrian, Paleozoic, Mesozoic, and Cenozoic ErasThe Geologic Time Scale is the history of the Earth broken down into four spans of time marked by various events, such as the emergence of certain species, their evolution, and their extinction, that help distinguish one era from another.
The five ages of man is a Greek creation story that traces the lineage of mankind through five successive "ages" or "races" including the Golden Age, the Silver Age, the Bronze Age, the Age of Heroes, and the present (to Hesiod) Iron Age.
Lasting roughly 2.5 million years, the Stone Age ended around 5,000 years ago when humans in the Near East began working with metal and making tools and weapons from bronze. During the Stone Age, humans shared the planet with a number of now-extinct hominin relatives, including Neanderthals and Denisovans.
10,000–9,000 years ago (8000 BC to 7000 BC): In northern Mesopotamia, now northern Iraq, cultivation of barley and wheat begins. At first they are used for beer, gruel, and soup, eventually for bread.
Scientists have just assigned three new ages to the Holocene, which is the current epoch in which we live. They're calling this most recent age the Meghalayan, which began 4,200 years ago during a worldwide megadrought. The Holocene commenced 11,700 years ago after the end of the last ice age.
The College Board has broken down the History of the World into six distinct periods (FOUNDATIONS, CLASSICAL, POST-CLASSICAL, EARLY-MODERN, MODERN, CONTEMPORARY.
