Document Summary
Primitive fern ophioglossum reticulatum has the highest known chromosome number of any plant, 2n = ca. Hierarchy - kingdom, phylum, subphylum, class, subclass, order, family, genus, species. A species is a different thing or looks different. Species not real, nature made up of individuals (not used) Concept based on relationship of two co-existing natural populations at a single locality (sympatric, synchronous - growing/living in same place, same time, but don"t interbreed). Considers a species as a group of populations that actually or potentially interbreed with each other. Involves any species concept or de nition that stresses reproductive isolation and a community gene pool. Species de ned by distinctiveness (shared traits) rather than by relative differences. Species consist of populations rather than unconnected individuals. Species are de ned by their reproduction isolation. Species is a population or group that has a unique closed genome component as well as a potentially non unique open genome component.
