Describe the process of speciation. include in your discussion the factors that may contribute to the maintenance of genetic isolation.

The process of speciation is the separation of a specific population into different species. The factors that may affect to maintain this genetic isolation are: allopatric, sympatric, prezygotic and postzygotic barriers. Allopatric barriers occurs when two species that are of the same family before cannot go back to the way they were before unless a contact between the two is established again. Sympatric are a group of species that shared the same family before but forced to evolve separately due to environmental factors. Prezygotic barriers are a group of species that are formed from the developing fertilized egg. 

an adaptation is a change or process by which an organism takes to be better suited for its environment. for example; migration is a behavioral adaptation, this is needed because birds are not built to last extremely cold climates. there are different adaptations because there are different species needing to adjust to different things, bears don't migrate; they hibernate.
