Theodosius Dobzhansky and Ernst Mayr contributed significantly to the understanding of species origin through the modern synthesis of evolutionary biology. They emphasized that species arise through a combination of genetic mutations, natural selection, and reproductive isolation. Dobzhansky highlighted the role of genetic diversity and adaptation in populations, while Mayr focused on the importance of allopatric speciation, where geographic barriers lead to the divergence of populations over time. Together, they articulated the mechanisms by which evolutionary processes can lead to the formation of new species.
Dobzhansky and Mayr's ideas about the origin of species build on Darwin's foundation by emphasizing the role of genetic variation and evolutionary processes in speciation. Like Darwin, they recognized natural selection as a key mechanism driving evolution, but they incorporated modern genetic understanding to explain how new species arise through population dynamics and reproductive isolation. Both perspectives highlight the gradual nature of speciation and the importance of adaptation to environmental changes, reinforcing the idea that species are not fixed but rather evolve over time.
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.
