Archaeology

Uruk (Erech in the Old Testament and Warka to Arabs), perhaps the first great city, is founded in Mesopotamia (Iraq) on the banks of the Euphrates River. See also 3500 bce Archaeology. (See essay.)

Communication

People in the Near East begin to use seals to identify property by stamping the seal into wet clay. See also 3000 bce Communication.

Food & agriculture

Olives are cultivated in Crete.

Rice is cultivated in Indochina (Thailand), probably having spread from a center in the Yangtze Delta. See also 5000 bce Food & agriculture; 2000 bce Food & agriculture.

The ard, a primitive form of plow, is in use in China. Plows pulled by cattle are known in northern Mesopotamia. See also 6000 bce Food & agriculture.

Maize, called corn in the United States, is domesticated in what is now the Tehuacán valley or nearby Oaxaca, Mexico. See also 7000 bce Food & agriculture.

Materials

The Egyptians and Sumerians smelt silver (make the metal from an ore). See also 4200 bce Materials.

A standard kiln is developed in Mesopotamia. The fire is in a hearth below a perforated separation from the kiln chamber where the pottery is held while it is being fired. See also 7000 bce Materials.

Iron beads are used in what is now Cairo, Egypt, as evidenced by oxidized remains of a string of them. This is the earliest direct proof of human use of iron. See also 3500 bce Materials.

Mathematics

The simple tokens that have been used for keeping numerical records since about 8000 bce are first supplemented by complex tokens that have marks on them or that are in new and varied shapes (the earlier, unmarked tokens were almost all simple geometric shapes or representations of jars or animals). See also 8000 bce Mathematics; 3700 bce Mathematics.

A system of numeration begins to be used in Egypt. (See essay.)

Transportation

Egyptians build boats made from planks joined together. Previously, boats were dugout canoes and possibly rafts of reeds bound together or skins stretched over a framework. See also 4300 bce Transportation.

Horses are being ridden in what is now Ukraine. See also 5000 bce Food & agriculture.

The 4th millennium BC saw major changes in human culture. It marked the beginning of the Bronze Age and of writing.

The city states of Sumer and the kingdom of Egypt were established and grew to prominence. Agriculture spread widely across Eurasia. World population in the course of the millennium doubled, approximately from 7 to 14 million people in the area surrounding them.

Based on studies by glaciologist Lonnie Thompson, professor at Ohio State University and researcher with the Byrd Polar Research Center, a number of indicators shows there was a global change in climate 5,200 years ago, probably due to a drop in solar energy output as hypothesized by Ohio State University.[1]

  • Plants buried in the Quelccaya Ice Cap in the Peruvian Andes demonstrate the climate had shifted suddenly and severely to capture the plants and preserve them until now.[2]
  • A man trapped in an Alpine glacier ("Ötzi the Iceman") is frozen until his discovery in 1991.[3]
  • Tree rings from Ireland and England show this was their driest period.[3]
  • Ice core records showing the ratio of two oxygen isotopes retrieved from the ice fields atop Africa's Mount Kilimanjaro, a proxy for atmospheric temperature at the time snow fell.[3]
  • Major changes in plant pollen uncovered from lakebed cores in South America.[3]
  • Record lowest levels of methane retrieved from ice cores from Greenland and Antarctica.[3]
  • End of the Neolithic Subpluvial, start of desertification of Sahara (35th century BC). North Africa shifts from a habitable region to a barren desert.[3]
