How Zoning Works: A zoning ordinance consists of two parts: a map (or series of maps) and text. The zoning map shows how the community is divided into different use districts or zones. Zoning districts common to most ordinances include residential, commercial, industrial, and agricultural. The zoning map must show precise boundaries for each district. Consequently, most zoning maps rely on street or property lines as district boundaries.
Hominin â the group consisting of modern humans, extinct human species and all our immediate ancestors (including members of the genera Homo, Australopithecus, Paranthropus and Ardipithecus). Current use of the term âhominidâ can be confusing because the definition of this word has changed over time.
The timeline of human evolution outlines the major events in the development of the human species, Homo sapiens, and the evolution of human ancestors. It includes brief explanations of some of the species, genera, and the higher ranks of taxa that are seen today as possible ancestors of modern humans. This timeline is based on studies from anthropology, paleontology, developmental biology, morphology, and from anatomical and genetic data.
