One Wheel Transport Evolution

The invention of the wheel thus falls in the late Neolithic, and may be seen in conjunction with the other technological advances that gave rise to the early Bronze Age. Note that this implies the passage of several wheel-less millennia even after the invention of agriculture and of pottery:
• 9500–6500 BCE: Aceramic Neolithic
• 6500–4500 BCE: Ceramic Neolithic (Halafian)
• ca. 4500 BCE: invention of the potter's wheel, beginning of the Chalcolithic (Ubaid period)
