Sympatric speciation specifically excludes?
Geographic Isolation
What is sympatric speciation?
When there is no physical barrier, a new species arises within the home range on an existing species.
How did the continental shift theory affect evolution?
The ultimate allopatric ( geographic ) speciation. If you had a population of quite similar organisms in a area that split the population into two or more populations when continental drift occurred you would have different mutations and changing environments putting selective pressure on two or more populations now.
What species concept should be used in the apple maggot fly case?
In the case of the apple maggot flies, it is an example of sympatric speciation. Two different populations occur in different niches where there is no gene flow between the two.
What is alopatric speciation?
Allopatric Species:%20%20species%20occupying%20areas%20separated%20by%20space%20or%20time','(allo%20=%20other,%20different;%20patri%20=%20fatherland,%20habitat)','../../sounds/bio303/allopatric.wav')" onmouseover="window.status='Occupy different areas'; return true">Allopatric species are species which, because they occupy areas separated by space (geographic isolation) or time, are reproductively isolated. It is often unknown whether, if brought together, they could actually interbreed. As an example, dogs and coyotes were originally allopatric species. However, when humans and their dogs moved into coyote-inhabited areas, it was discovered that dogs and coyotes are capable of interbreeding and producing viable offspring. By now, there are so many dog genes in the coyote population that there may no longer be any such thing as a 100% coyote. for further references see: http://biology.clc.uc.edu/Courses/bio303/natural%20selection.htm
How is sympatric speciation similar allopatric speciation?
They both are mechanisms by which new species arise
Types of Speciation?
sympatric , allopatric and parapatric 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.
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.
Are Darwin's finches allopatric or sympatric?
no
Why similar organisms do not interbreed because of a physical barrier?
Allopatric Speciation

Describes why similar organisms do not interbreed because of a physical barrier?
Allopatric Speciation
Which form of speciation is most rapid A. sympatric speciation via character displacement B. allopatric speciation on the island archipelagos C. sympatric speciation via autopolyploidy D. allopa?
B. Allopactric speciation on island archipelagos. As the organisms move from island to island rapid speciation is observed because of variations in resource acquisition more than just variation in environment. Amplified radiation is observed. Example is finches on the Galapagos Islands. Hawaii also gives this example.
What type of selection can create 2 new species from one population?
There are several types of selections that can do this. It includes allopatric speciation where the population is separated by physical barrios, sympatric speciation where variations occur in the population, and allopolyploid when two species merge.
The emergence of new species when a population becomes geographically isolated is termed what?
This concept is called allopactric speciation.
