When there is no physical barrier, a new species arises within the home range on an existing species.
Geographic isolation as a mechanism for reproductive isolation. In sympatric speciation, new species arise within the same geographic area without physical barriers separating populations. This process typically involves ecological, behavioral, or genetic factors leading to reproductive isolation within a single population.
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 through which new biological species arise. It typically occurs when populations of a species become isolated, leading to genetic divergence due to factors such as natural selection, mutation, or genetic drift. Over time, these changes accumulate, resulting in reproductive barriers that prevent interbreeding between the populations, ultimately leading to the formation of distinct species. This process can happen through mechanisms such as allopatric, peripatric, parapatric, or sympatric speciation.
Speciation is the evolutionary process by which new biological species arise.
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.

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
Sympatric speciation refers to the formation of two or more descendant species from a single ancestral species all occupying the same geographic location. Often cited examples of sympatric speciation are found in insects that become dependent on different host plants in the same area.

-rapid speciation -sexual selection
sympatric speciation. This occurs when two subpopulations of a species evolve into distinct species without geographical isolation, often due to factors such as disruptive selection or polyploidy.
