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.
When there is no physical barrier, a new species arises within the home range on an existing species.

Sympatric Speciation
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.
They both are mechanisms by which new species arise
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.
Sympatric speciation is the process by which new species evolve from a single ancestral species in the same geographical area, without physical isolation. It typically involves changes in behavior, diet, or habitat preferences that lead to reproductive isolation between different groups within a population, eventually leading to the formation of distinct species.

This process is known as sympatric speciation, where a new species evolves from a common ancestor within the same geographical area without a physical barrier. It can happen due to factors like polyploidy, habitat differentiation, or behavior isolation.
Allopatric speciation occurs when a population is geographically isolated, leading to the development of new species due to evolutionary pressures in different environments. In contrast, sympatric speciation happens when new species arise within the same geographic area, often due to factors like behavioral changes, polyploidy in plants, or niche differentiation. While allopatric speciation relies on physical barriers, sympatric speciation can occur without such barriers, emphasizing reproductive isolation mechanisms.
