There are no discrete steps to speciation. There are a number of boundary conditions that are met in most cases. Speciation is the result of any situation that leads to the genetic, behavioural and/or morphological divergence of subpopulations of the same species, which may in turn lead to a decline in interbreeding frequency. The causes for such divergence may vary. The clearest example of the principle is when two subpopulations become geographically isolated (for instance due to migration, floods or some other natural event), and diverge as a result of genetic drift. Once the two population have diverged to the degree that they would no longer produce fertile offspring together even if they were put back together again, we say that speciation has occurred.

Which type of evolution requires speciation?
Speciation is the evolutionary process by which new biological species arise.
One species evolves into another through the process of adaptation or speciation?
Is speciation b/c my science teacher told me that.
What affect do humans have on speciation?
As part of the environment of other organisms humans can have great effects on speciation. Especially adaptive radiation. As we contribute heavily to the extinction of some species other species flow into those open niches and radiate outwards to possible speciation.
What effect would a very short generation time such as bacteria have on speciation?
Well they would evolve faster, so speciation would occur faster too
Sympatric speciation specifically excludes?
Geographic Isolation
What are two main steps in speciation?
finding two different sex's of animals and breeding them.. and makeing sure they are compatible.
What are three events that can lead to speciation?
Species (phylogenetically and genetically distinct animals from a common ancestor) form when barriers exist to prevent outbreeding. These are usually environmental (e.g. mountain ranges, oceans, climatic barriers) or biological (e.g. interbreeding of two species results in an infertile offspring).
Speciation caused by change in the course of a river is an example pf divergent speciation?
Allopatric speciation.
Types of Speciation?
sympatric , allopatric and parapatric speciation
What is necessary for speciation to occur?
Isolation Is necessary for speciation to occur.
Why does polyploidy not cause speciation or even be associated with speciation?
Actually it is.
Complete reproduction isolation is evidence that what has occurred?
speciation
Home of the independent response to separation?
