Question

How did Dobzhansky and Mayr explain the origin of species?

It happens through allopatric speciation.

It happens through adaptation by natural selection.

It happens through sympatric speciation.

Answer 1

Dobzhansky and Mayr explained the origin of species through allopatric speciation, where populations become geographically isolated and evolve separately, eventually leading to the formation of new species. They also emphasized the role of adaptation by natural selection in driving the evolutionary process. While sympatric speciation, where new species arise within the same geographical area, is also possible, Dobzhansky and Mayr primarily focused on allopatric speciation as the primary mechanism of speciation.
