when did the paleolithic period start and end
Paleolithic The Paleolithic (or "Palaeolithic")/ˌpæliːəˈlɪθɪk/ age is a prehistoric period of human history distinguished by the development of the most primitive stone tools and covers roughly 95% of human technological prehistory.[1] It extends from the earliest known use of stone tools, probably by Homo habilis initially, 2.6 million years ago, to the end of the Pleistocene around 10,000 BP.[2]
Early modern period The early modern period of modern history follows the late Middle Ages of the post-classical era. Although the chronological limits of the period are open to debate, the timeframe spans the period after the late portion of the post-classical age (c. 1500), known as the Middle Ages, through the beginning of the Age of Revolutions (c. 1800) and is variously demarcated by historians as beginning with the Fall of Constantinople in 1453, with the Renaissance period, and with the Age of Discovery (especially with the voyages of Christopher Columbus beginning in 1492, but also with Vasco da Gama's discovery of the sea route to the East in 1498), and ending around the French Revolution in 1789.
