Dobzhansky and Mayr's ideas about the origin of species are similar to Darwin's in that they all propose natural selection as the main mechanism driving evolution. They also emphasize the importance of variation within populations as the raw material for evolution to occur. Additionally, they highlight the concept of species diverging from common ancestors through the process of adaptation to different environments.

In the 1930s, Dobzhansky and Mayr explained that species originate through allopatric speciation.
Dobzhansky and Mayr explained the origin of species through the process of natural selection and genetic variation. They proposed that species evolve over time through the accumulation of small, gradual changes, leading to the formation of new species. Dobzhansky's concept of genetic drift and Mayr's theory of geographic isolation also played key roles in their explanations.
