Speciation : Biogeography
Speciation Speciation is the process by which a new kind of plant or animal species is created. It occurs when a group within a population separates from other members and develops its own unique characteristics t o form a new species. Geographical / Allopatric speciation It is also called as allopatric speciation . It is the method by which geographical isolation stops the connection between interbreeding members of the same population. A physical barrier, such as a mountain range or a waterway, makes it impossible for them to breed with one another. Each species develops differently based on the demands of their unique habitat or the genetic characteristics of the group that are passed onto offspring forming two different species in the long term. Example: The elephant population in Africa and India evolved separately forming different species of the same population. Marsupials developed as Kangaroo in Australia, Opossum in South America, Tasmanian...
