During the Neolithic Age (approximately 10000 BCE), early man evolved from hunter-gatherer to farmer and agriculturalist, living in larger, permanent settlements with a variety of domesticated animals and plant life. This transition brought about significant changes in terms of the economy, architecture, man's relationship to the environment, and more.
Now Dr. Ran Barkai of Tel Aviv University's Department of Archaeology and Ancient Near Eastern Civilizations has shed new light on this milestone in human evolution, demonstrating a direct connection between the development of an agricultural society and the development of woodworking tools.
"Intensive woodworking and tree-felling was a phenomenon that only appeared with the onset of the major changes in human life, including the transition to agriculture and permanent villages," says Dr. Barkai, whose research was published in the journal PLoS One. Prior to the Neolithic period, there is no evidence of tools that were powerful enough to cut and carve wood, let alone fell trees. But new archaeological evidence suggests that as the Neolithic age progressed, sophisticated carpentry developed alongside agriculture.
Evolution of axes
The use of functional tools in relation to woodworking over the course of the Neolithic period has not been studied in detail until now. Through their work at the archaeological site of Motza, a neighbourhood in the Judean Hills, Dr. Barkai and his fellow researchers, Prof. Rick Yerkes of Ohio State University and Dr. Hamudi Khalaily of the Israel Antiquity Authority, have unearthed evidence that increasing sophistication in terms of carpentry tools corresponds with increased agriculture and permanent settlements.
The early part of the Neolithic age is divided into two distinct eras -- Pre-Pottery Neolithic A (PPNA) and Pre-Pottery Neolithic B (PPNB). Agriculture and domesticated plants and animals appear only in PPNB, so the transition between these two periods is a watershed moment in human history. And these changes can be tracked in the woodworking tools which belong to each period, says Dr. Barkai.
Within PPNA, humans remained gatherers but lived in more permanent settlements for the first time, he says. Axes associated with this period are small and delicate, used for light carpentry but not suited for felling trees or other massive woodworking tasks. In PPNB, the tools have evolved to much larger and heavier axes, formed by a technique called polishing. The researchers' in-depth analysis of these tools shows that they were used to cut down trees and complete various building projects.
"We can document step by step the transition from the absence of woodworking tools, to delicate woodworking tools, to heavier woodworking tools," Dr. Barkai says, and this follows the "actual transition from the hunter-gatherer lifestyle to agriculture." He also identifies a trial-and-error phase during which humans tried to create an axe strong enough to undertake larger woodworking tasks. Eventually, they succeeded in creating a massive ground stone axe in PPNB.

Early human beings were nomads. They were completely dependent on hunting and gathering. But gradually they began developing permanent settlements. The permanent settlements of human beings came into existence only after the advent of agriculture. The settled agriculture led humans to settle in one place. The early humans settled near lakes and rivers. Thereon, the surplus production of early humans made them contact others, and this is how permanent settlement led to the development of civilization.
