<p class="p__0">This use of refined stone axes increased considerably in the Neolithic, but were originally used in the preceding Mesolithic in some areas such as Ireland. Agriculture fed larger populations, and the shift to sedentism allowed at the same time raising more kids, as babies no longer required to be carried, as nomadic ones must.</p>
<br>
<p class="p__1">With this increase in population and availability of labor came an increase in labor expertise. What triggered the progression from early Neolithic villages to the first cities, such as Uruk, and the very first civilizations, such as Sumer, is not particularly understood; however, the development of significantly hierarchical social structures and specialized labor, of trade and war amongst adjacent cultures, and the need for collective action to overcome ecological difficulties such as irrigation, are all believed to have actually contributed.</p>
<br>
<p class="p__2">The benefits of copper tools over stone, bone, and wooden tools were quickly obvious to early human beings, and native copper was probably used from near the beginning of Neolithic times (about 10 ka). Native copper does not naturally happen in large quantities, however copper ores are quite typical and a few of them produce metal quickly when burned in wood or charcoal fires.</p>

<p class="p__3">The very first uses of iron alloys such as steel dates to around 1800 BCE. top 5,top 10,inventions,gadgets,amazing inventions you must see,you won’t believe exist,inventions you must have,things that actually exist,amazing inventions at home,tech,features,specs,homemade 2016,handmade,facts,2017,list,homemade,top5s,maquinas,2016,test,technology,gadget,cool gadgets,accessories,futuristic,awesome inventions and transport The wheel was invented circa 4000 BCE. Meanwhile, people were finding out to harness other types of energy. The earliest recognized use of wind power is the sailing ship; the earliest record of a ship under sail is that of a Nile boat dating to the 8th-millennium BCE.</p>

<p class="p__4">The ancient Sumerians in Mesopotamia utilized a complex system of canals and levees to divert water from the Tigris and Euphrates rivers for irrigation. According to archaeologists, the wheel was created around 4000 BCE probably individually and nearly at the same time in Mesopotamia (in contemporary Iraq), the Northern Caucasus (Maykop culture) and Central Europe.</p>
<br>
<p class="p__5">The oldest artifacts with drawings depicting wheeled carts date from about 3500 BCE; however, the wheel may have remained in usage for centuries before these drawings were made. More just recently, the oldest-known wood wheel in the world was found in the Ljubljana marshes of Slovenia. The development of the wheel transformed trade and war.</p>
