Allopatric speciation: ( other country ) A speciation event that is facilitated geographically. A population is split along geographic lines, mountains, rivers, and the now separate gene pools vary in allele frequency over time enough to , possibly, have two new species arise.
Sympatric speciation: ( same country ) An in place speciation event where a sub-population within a population begins to vary their alleles from the main population. Perhaps a slight temporal, or water level difference, or mating differences can facilitate this. This speciation event is still a matter of contreversy in Biology.

Which of the following can result in instant speciation?
Allopatric speciation and sympatric speciation are two factors. Allopatric speciation occurs when physical barriers are formed, separating the specie. This will cause the specie to evolve at different rates causing a new specie to form. Sympatric speciation is less likely to occur when comparing it to allopatric. In sympatric speciation is no longer physical but generic. For example a mutation in the genetic order of the specie (which does not happen as often as physical barriers), and a different mating preference/season.
What is the is the first step in allopatric speciation?
physical isolation of two populations
Process in which isolated populations of the same species become new species is called?
In Sympathetic Speciation, a species evolves into a new species without any barriers that separate the populations.In Allopatric Speciation, a population divided by a barrier, each population evolves separately, and eventually two populations cannot successfully interbreed.
What similar organisms do not interbreed because of a physical barrier?
Allopatric Speciation : NovaNet
Describes why similar organisms do not interbreed because of a physical barrier?
Allopatric Speciation
Types of Speciation?
sympatric , allopatric and parapatric speciation
What best describes how long it usually takes for speciation to occur?
species originate through allopatric speciation
The emergence of new species when a population becomes geographically isolated is termed what?
This concept is called allopactric speciation.
Compare and contrast allopatric and sympatric speication?
Allopatric and sympatric speciation are both methods by which new species arise. However, allopatric speciation is when species interbreed. Sympatric speciation is when several new species arise from a common ancestor.
Speciation caused by change in the course of a river is an example pf divergent speciation?
Allopatric speciation.
Allopatric speciation requires?
geographic isolation.
Which type of speciation occurred among galapagos islands finches?

How is sympatric speciation similar allopatric speciation?
They both are mechanisms by which new species arise
