‘dynamic habitat’ hypothesis


‘dynamic habitat’ hypothesis
  Premise which suggests that cycad species are rapidly and dynamically evolving in response to climatic changes caused by glacial cycles, as opposed to the traditional view that species are slowly evolving and relictual; originally proposed in reference to species of Dioon in Mexico (sensu Gregory & Chemnick, 2004).
