Speciation and Diversity

What is a Species?
Overview A species is a group of organisms that interbreed and produce fertile offspring. Typically, individuals of the same species appear similar…
Formation of Species
31.2: Formation of Species
Speciation describes the formation of one or more new species from one or sometimes multiple original species. The resulting species are discrete…
Speciation Rates
31.3: Speciation Rates
Overview Speciation usually occurs over a long evolutionary time scale, during which the species may be isolated or continue to interact. If two…
