Astudent 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.

The correct answer is option A

Speciation can be defined as the the evolutionary process by which a species gets converted into the distinct species. The evolution can be due to many reasons.

Speciation can be caused due to geographical isolation which means geography can be one of the reasons for the isolation and speciation of species.

Some other examples are behavioral isolation.
