Sympatric speciation occurs when new species arise within the same geographic area, often due to reproductive isolation mechanisms like behavioral differences, polyploidy in plants, or habitat differentiation. In contrast, allopatric speciation takes place when populations are geographically separated, leading to divergence due to physical barriers like mountains or rivers. The key difference lies in the geographical context: sympatric speciation involves populations that coexist, while allopatric speciation involves populations that are isolated from each other.

How does sympathetic speciation differ from allopathic speciation?
Sympatric speciation occurs when new species arise from a single ancestor species while inhabiting the same geographic region, often due to factors like behavioral changes, polyploidy, or ecological niches. In contrast, allopatric speciation happens when populations are geographically isolated, leading to reproductive isolation as they adapt to their separate environments. The key difference lies in the geographic context: sympatric speciation occurs without physical barriers, while allopatric speciation relies on such barriers.
How is symmetric speciation to allopatric speciation?
Symmetric speciation and allopatric speciation are two different processes of species formation. Allopatric speciation occurs when populations are geographically separated, leading to reproductive isolation and divergence due to different environmental pressures. In contrast, symmetric speciation refers to the process where species diverge while remaining in the same geographical area, often through mechanisms such as ecological niche differentiation or sexual selection. While both processes result in the formation of new species, they differ primarily in their geographic context and the mechanisms driving reproductive isolation.
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.

Types of Speciation?
sympatric , allopatric and parapatric 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.
