Question

What is Sympatric speciation?

Answer 1

Hint: We have to remember that the edward Bagnall Poulton, who describes the derivation, coined the word in 1904. One of the three common spatial modes of speciation is sympatric speciation. Sympatric speciation can be seen in a variety of species, including bacteria.

Complete answer:
We can discuss the sympatric speciation that occurs when a new species evolves from a living ancestral species as both remain in the same geographic area. Sympatric and sympatry are words used in evolutionary biology and biogeography to describe species whose ranges overlap and they occur together at least in some areas. Such a distribution may be the result of sympatric speciation if these organisms are closely related (e.g. sister species). The lack of gene flow facilitates divergence in this case. The evolution of geographically related groups into distinct species is known as parapatric speciation. The evolution of species triggered by the geographic separation of two or more populations of a species is known as allopatric speciation.
Divergence occurs despite minimal interbreeding between the two diverging groups as they come into contact in this case. Interbreeding is not limited by geography in sympatric speciation. These are special cases of a continuum of spatial segregation of diverging lines ranging from zero (sympatric) to total (allopatric).

Note:
We must know that the sympatric speciation happens when two groups of the same species remain in the same geographic area but grow at different rates until they can no longer interbreed and are classified as separate species. It differs from other forms of speciation, which occurs when a population is divided into groups due to a geographic barrier or migration.
