 1. Dates for the Paleolithic age are based on stone tool types and vary by location:
 Mya - Million Years ago, BP - Before Present
 - Lower 2.5 Mya - 300,000 | 2,5 Mya - 200,000 BP
 - Middle - 300,000-30,000 | European 150,000- 35,000
 - Upper:  40,000-10,000 | 100,000 - 11,000
 In the 2nd edition of World Prehistory, 1969, Grahame Clarke envisioned an evolutionary progression of flint-knapping in which the "dominant lithic (stone tool making) technologies" occurred in a fixed sequence from Mode 1 through Mode 5.
 
* Dates for the Bronze and Iron age as well as the Mesolithic and Neolithic periods vary from society to society.The Iron age begins in the 12th century BC in the ancient Near East, and ancient Greece, the 8th century BC in Central Europe and the 6th century BC in Northern Europe.
 In some areas of the world the Bronze Age followed the Neolithic age. On the other hand, in many parts of sub-Saharan Africa, the Neolithic age is directly followed by the Iron Age.
 In some places there was a copper age between the Stone and Bronze ages.
 
Bronze is made of copper and tin. Bronze and tin are relatively easy to extract from ore, whereas iron ore requires a much more energy intensive and complicated process to smelt.With the collapse of the Bronze Age around 1200 B.C.E. trade networks fell apart and metallurgists could not get tin and began to work with iron.

 - There doesn't seem to be general agreement on Era's:Modern history books have gotten away from using these classifications, possibly because dates vary from civilization to civilization.
 Some include Medieval and Industrial periods as Eras and some don't.
 Ancient: 2,000 BCE - 1,000 | CE, 3,110 BCE - 500 CE | 4,000 BEC - 8 BCE
 Medieval: 1000 - 1600 | 600-1,500
 Modern: 1500- | 1,600-
 Industrial Era: 1750-1850
 
These eras of man are different from the geological eras.  We are in theCenozoic gelogical era (65 Mya - today), Quaternary Period (1.8 Mya).
 Pleistocene Epoch 1.8 Mya - 11,000 bp, Holocene Epoch 11,000 years ago - today.
   - In Robert Wright's 2000 book "Nonzero:", he makes the point for innovation as a function of population density.
 
The paper "Cultural Innovations and Demographic Change",  Human Biology - Volume 81, Numbers 2-3, April-June 2009, by Peter J. Richerson et. al.  Department of Environmental Science and Policy, UC Davis, states "Demography plays a large role in cultural evolution through its effects on the effective rate of innovation."
