History of anthropology
The first use of the term "anthropology" in English to refer to a natural science of humanity was apparently in Richard Harvey's 1593 "Philadelphus, a defense of the legend of Brutus in British history", which, includes the passage: "Genealogy or issue which they had, Artes which they studied, Actes which they did. This part of History is named Anthropology."
Early anthropocene
The Early Anthropocene Hypothesis (sometimes called Early Anthropogenic) was proposed by William Ruddiman. It posits that the Anthropocene era, as some scientists call the most recent period in Earth's history when the activities of the human race first began to have a significant global impact on Earth's climate and ecosystems, did not begin in the eighteenth century with advent of coal-burning factories and power plants of the industrial era, as was commonly assumed, but dates back to 8,000 years ago, triggered by intense farming activities after agriculture became widespread. It was at that time that atmospheric greenhouse gas concentrations stopped following the periodic pattern of rises and falls that had accurately characterized their past long-term behavior, a pattern that is explained by natural variations in Earth's orbit known as Milankovitch cycles.
