A variety of mechanisms have been proposed to describe how speciation can occur. The two most important mechanisms are undoubtedly allopatric and sympatric speciation. How do these two processes work to produce new species?© BrainMass Inc. brainmass.com October 1, 2020, 8:12 pm ad1c9bdddf
Speciation is the splitting of one species into two or more species or the transformation of one species into a new species over time. Speciation can be defined operationally as the evolution of a genetically-based barrier to gene exchange. It leads to the formation of populations that are genetically ...
Speciation is the transformation of one species into a new species over time. It leads to the formation of populations that are genetically different and reproductively isolated from the original population. It can result in either the bifurcation of a single lineage into two (cladogenesis) or the change over time of a single lineage (anagenesis).
There are two popular mode of speciation - Allopatric and sympatric.
