Copper is mined before 4500 BCE at the eastern European sites of Ai Bunar, near Stara Zagora in Bulgaria, and Rudna Glava in present-day eastern Serbia.

At the latter site, which pottery finds show to belong to the Vinca culture, shafts are cut into the hillside, with scaffolding constructed for easy access to the veins of ore.

The uniformity of design characteristic of Linear Pottery sites begins to break down around as various regional groups emerge, such as the Rössen, Lengyel, Tisza, and Stroke-ornamented Pottery (Stichbandkeramik) cultures.

Ubaid 2, sometimes called Hadji Muhammad (4800–4500 BCE), after the type-site of the same name, has seen the development of extensive canal networks from major settlements.

Irrigation agriculture, which seem to have developed first at Choga Mami (4700–4600 BCE), a Samarra ware archaeological site of Southern Iraq which shows the first canal irrigation in operation at about 6000 BCE, and rapidly spread elsewhere.

It is not clear which way cultural developments were flowing in the 6500 to 4500 BCE period.

The Las Vegas culture, the first known in Ecuador, lives on the Santa Elena Peninsula on the coast of Ecuador between 8000–4600 BCE.

The skeletal remains and other finds show evidence the culture once flourished in the area.

Scientists have classified three phases of cultural development.

The earliest people were hunter-gathers and anglers.

Approximately 6000 BCE, the culture were among the first to begin farming (bottle gourd, Lagenaria siceraria, and an early type of maize, Zea mays L.) The best-known remains of the culture are The Lovers of Sumpa.

These human remains and other items can be seen at Museo Los Amantes de Sumpa y Centro Cultural in Santa Elena.

Bone points and a spatula have been discovered that may have been used for making nets or textiles, along with various tools and containers shaped of shell; archaeologist believe that wood, bamboo, reeds, and bark were used in the tool industry.

Although mummies have not been documented from coastal Ecuador, the Las Vegas people were contemporaneous with and similar to the people whose remains are preserved as the Chinchorro mummies of the north coast of Chile.

The Akahoya eruption, one of the largest eruptions during the Holocene, ocurring around 4350 BCE, ejects about one hundred and fifty cubic kilometers (thirty-six cubic miles) of tephra, giving it a 7 on the Volcanic Explosivity Index.

One of only six known eruptions reaching that magnitude during the Holocene, or the last twelve thousand years, it forms the massive, mostly submerged Kikai Caldera, up to nineteen kilometers (twelve miles) in diameter in the Osumi Islands of Kagoshima prefecture, Japan.

Pyroclastic flows from that eruption reach the coast of southern Kyushu up to one hundred kilometers (sixty-two miles) away, and ash falls as far as Hokkaido.

It dramatically changes vegetation in Southern Kyūshū.

Archaeologically it has been dated around 7,300 cal. BP during the Earliest Jōmon period, but it has also been radiocarbon dated to 6,500 BP.

The very earliest plow was the simple scratch-plow, or ard, which consists of a frame holding a vertical wooden stick that was dragged through the topsoil (still used in many parts of the world).

It breaks up a strip of land directly along the plowed path, which can then be planted.

Because this form of plow leaves a strip of undisturbed earth between the rows, fields are often cross-plowed at ninety degree angles, and this tends to lead to squarish fields.

In the archaeology of northern Europe, such squarish fields are referred to as "Celtic fields.’

Farmers in the lower Danube region begin using cattle as plow animals by about 4500, at which time central and eastern European cultures begin to practice rich burial patterns.

The Middle East (4509–4366 BCE): Chalcolithic Expansion and Animal Domestication

Occupation of Tepe Yahya

Between 4509 and 4366 BCE, the archaeological site of Tepe Yahya, located approximately 225 kilometers (140 miles) south of Kerman in present-day Iran, began its initial occupation around 4500 BCE. This site became an important center of early human settlement and technological advancement in the region.

Chalcolithic Technological Spread

By 4500 BCE, the Chalcolithic era—characterized by the concurrent use of copper and stone tools—had spread widely throughout the Fertile Crescent. This marked significant technological advancement, fostering improved tools and greater efficiency in daily activities, agriculture, and trade.

Domestication and Agricultural Development

The domestication of oxen, which possibly began as early as the sixth millennium BCE in Mesopotamia, profoundly impacted agricultural practices by providing farmers with the necessary power for developing plowing techniques. The introduction of the plow significantly enhanced agricultural productivity and facilitated expansion into previously difficult-to-cultivate areas.

Regional Animal Domestication

Animal domestication continued extensively across the region, reaching as far north as present-day Turkey and as far south as the Zagros Mountains. These practices supported increasingly stable and productive agricultural systems, contributing to the prosperity and expansion of communities across a broad geographic area.

This period highlights significant advancements in technology, agriculture, and domestication, underpinning further social and economic developments across the ancient Middle East.

Tepe Yahya, an archaeological site in present Iran, one hundred and forty miles (two hundred and twenty-five kilometers) south of Kerman is occupied from 4500.

The Chalcolithic, or copper- and stone-working technology, encompasses the Fertile Crescent by 4500 BCE.

There are also tribes that practice domesticating animals as far north as Turkey, and as far south as the Zagros Mountains.
