Speciation

Speciation: The Formation of New Species

Speciation is the evolutionary process by which populations evolve to become distinct species. It involves the interruption of gene flow and the development of reproductive isolation.

  • Biological Species Concept
  • Gene flow
  • Reproductive isolation
  • Prezygotic barriers
  • Postzygotic barriers
  • Allopatric speciation
  • Sympatric speciation
  • Polyploidy
  • Habitat differentiation
  • Sexual selection
