Unit 2: Ages
Mesolithic Age - 10000 - 4000 BC
Associated with the rise to dominance of microlithic or very small geometric form tools commonly used in composite tools. Major impacts on history include the gradual domestication of plants and animals leading to the first settled communities.
Industrial Age 1750 - 1950 AD
Characterized by first use of complex machinery, and factories. People move from agricultural to industrial societies. Major impacts to history include the creation of large urban centers, population expansion, improved standards of living.
Iron Age - 700 BC - 450 AD
Characterized by iron being used as the main metal for tools and weapons. Major impacts on history include military dominance with the use of iron weapons and iron blade plows increased food production.
Neolithic Age - 4000 - 2300 BC
Characterized by the development of agriculture and an increasing emphasis on year-round settlements. Major impacts on history include developing a dependable year-round food supply which allowed more time for invention and innovation.
Bronze Age - 2300 - 700 BC
Characterized by the development of metallurgy, mainly the combining of copper and tin to make bronze. Major historical impacts include the gradual replacement of stone tools with metal ones which enabled humans to alter their environment at a more rapid pace.
Paleolithic Age - 500000 - 10000 BC
Characterized by the earliest known stone tools. Major impacts on history include better hunting and defense.
Information Age - 1950 - Present
Characterized by the gathering, manipulation, classification, storage, and retrieval of information. Exponential Growth and technological obsolescence
