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

Answer

Brief Explanations:

Speciation can be driven by various factors. Biological forces like genetic mutations, natural selection, and reproductive isolation (other than geographical) can lead to the formation of new species. Variation within a population can accumulate over time and result in speciation. Adaptive radiation is actually a process related to speciation where multiple new species arise from a common ancestor. Geographical isolation is just one of the mechanisms for speciation, not the only one.

Answer:

Speciation can occur from biological forces as well.
