  • In the mid‐20th century, Ernst Mayr (1942) and Theodosius Dobzhansky (1958) championed the significance of ‘circular overlaps’ or ‘ring species’ as the perfect demonstration of the gradual nature of species formation. As an ancestral species expands its range, wrapping around a geographic barrier, derived taxa within the ring display interactions typical of populations, such as genetic and morphological intergradation, while overlapping taxa at the terminus of the ring behave largely as… CONTINUE READING
