What are the four types of speciation?

Speciation is of following types.

  • Allopatric Speciation (alios— other, patria— native land): In this type of species formation, a part of the population becomes geographically isolated from the main population.
  • Sympatric Speciation (sym— together, patria— native land):
  • Parapatric Speciation:
  • Quantum Speciation:

What is the study of speciation?

The scientific study of speciation — how species evolve to become new species — began around the time of Charles Darwin in the middle of the 19th century. Many naturalists at the time recognized the relationship between biogeography (the way species are distributed) and the evolution of species.

What are the mechanisms of speciation?

Two mechanisms of speciation are allopatric (“other fatherland”) and sympatric (“together in the fatherland”) forms. In both cases, a single population divides into two, and heritable differences eventually prevent gene flow between the two through reproductive isolation.

What are the results of speciation?

When a certain number of species from a population migrate from one geographical region to another, the species might accumulate characteristics which are different from that of the original population. Migration usually results in geographical isolation and ultimately leads to speciation.

What is Allo and Patric?

By Ilmari Karonen [ GFDL, CC-BY-SA-3.0 or CC BY-SA 2.5-2.0-1.0], via Wikimedia Commons. The prefix allo- means “other.” The suffix -patric, means “place.” So allopatric is a type of speciation caused by geographic isolation. The individuals that are isolated are literally in an “other place.”

Why do we study speciation?

Speciation provides the framework for evolutionary biologists to understand and organize the earth’s biodiversity. Studying speciation requires that we look at how ecology determines evolution, and vice versa.
