When there is no physical barrier, a new species arises within the home range on an existing species.
Geographic Isolation
They both are mechanisms by which new species arise grad point
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.
Speciation is the evolutionary process by which new biological species arise.
Is speciation b/c my science teacher told me that.
sympatric , allopatric and parapatric speciation
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.
They both are mechanisms by which new species arise
Geographic Isolation
Sympatric Speciation develops within the range of the parent population. This type of speciation does not include geographical isolation, and can occur rapidly if a genetic change results in a barrier between the mutants and the parent population.

Sympatric Speciation
Sympatric speciation occurs when a plant population becomes reproductively isolated while living with its parent population. This occurs without physical separation, often driven by ecological or behavioral factors that prevent interbreeding between the populations.
