Problem: Modern history:

The Age of Enlightenment is a time in Western philosophy and cultural life centered upon the 18th century in which reason was advocated as the primary source and legitimacy for authority. Enlightenment gained momentum more or less simultaneously in many parts of Europe and America. Developing during the Enlightenment era, Renaissance humanism as an intellectual movement spread across Europe. The basic training of the humanist was to speak well and write (typically, in the form of a letter). The term umanista comes from the latter part of the 15th century. The people were associated with the studia humanitatis, a novel curriculum that was competing with the quadrivium and scholastic logic.

Problem: Biodiversity:

The term biological diversity was used first by wildlife scientist and conservationist Raymond F. Dasmann in the year 1968 lay book A Different Kind of Country advocating conservation. The term was widely adopted only after more than a decade, when in the 1980s it came into common usage in science and environmental policy. Thomas Lovejoy, in the foreword to the book Conservation Biology, introduced the term to the scientific community. Until then the term "natural diversity" was common, introduced by The Science Division of The Nature Conservancy in an important 1975 study, "The Preservation of Natural Diversity." By the early 1980s TNC's Science program and its head, Robert E. Jenkins, Lovejoy and other leading conservation scientists at the time in America advocated the use of the term "biological diversity".

What term was common before biological diversity?

A: "natural diversity"
