centre of origin

centre of origin A geographical location or local region (often in the tropics) where a particular group of organisms is believed to have originated. Many authorities believe centres of origin are also centres of diversity. For example, there are 6 genera of Palmae (palms) in the lower part of the Amazon basin, twice the number found anywhere else. It is difficult, however, to reconcile this explanation of centres of origin with the concept of allopatric speciation.

Citation styles

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

Notes:
  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.

centre of origin

centre of origin The region where a particular group of organisms is believed to have originated. Many authorities believe centres of origin are also centres of diversity. For example, the tropical timber-tree family Dipterocarpaceae is strongly concentrated in the Malay Peninsula, Sumatra, and Borneo, although it ranges from Africa to New Guinea. It is difficult, however, to reconcile this explanation of centres of origin with the concept of allopatric speciation.
