What idea would follow from the dobzhansky Mayr theory of speciation?

An idea that may follow from the Dobzhansky-Mayer theory of speciation is the concept of reproductive isolation as a key driver of speciation. This theory emphasizes the role of genetic mutations and natural selection in driving populations to diverge into distinct species through mechanisms such as geographic isolation and adaptation to different ecological niches. It also highlights the importance of genetic drift and gene flow in shaping the evolutionary process of speciation.
