allopatric

Examples of allopatric in the following topics:

• Allopatric Speciation

  • Allopatric speciation occurs when a single species becomes geographically separated; each group evolves new and distinctive traits.
  • This is known as allopatric speciation.
  • Biologists group allopatric processes into two categories: dispersal and vicariance.
  • Scientists have documented numerous cases of allopatric speciation.
  • The owl is an example of allopatric speciation.

• Speciation

  • Biologists have proposed mechanisms by which this could occur that fall into two broad categories: allopatric speciation and sympatric speciation.
  • Allopatric speciation (allo- = "other"; -patric = "homeland") involves geographic separation of populations from a parent species and subsequent evolution.

• Sympatric Speciation

  • The prefix "sym" means same, so "sympatric" means "same homeland" in contrast to "allopatric" meaning "other homeland."
  • The prefix "allo-" means "other" (recall from allopatric).

• Whole-Genome Duplication

  • The prefix "allo" means "other" (recall from allopatric); therefore, an allopolyploid occurs when gametes from two different species combine.
