A student argues that being separated geographically is the only way for speciation to occur. Why is he wrong? Speciation does not usually rely on geographic isolation. Speciation can occur from biological forces as well. Speciation can occur from variation as well. Speciation does not result from adaptive radiation.

Conceptive boundaries are essential too in that they save adjustments, yet as has been worried by botanists for near a century, they once in a while shield the whole genome from quality stream in as of late veered species.
In opposition to early perspectives, it is currently evident that specialization can happen within the sight of quality stream.
Speciation does not result from adaptive radiation is false as new species in sympatric speciation results from differentiation in food source, shelter or other characteristics.
There are 4 types of speciation: allopatric, peripatric, parapatric, and sympatric.
The first three occurs in the presence of a physical barrier. However, sympatric speciation does not occur in a presence of a barrier but as a result of adaptive radiation.
