Ernst Mayr Series
July 5, 1904 – February 3, 2005
Ernst Mayr was a pivotal figure in 20th-century evolutionary biology, instrumental in shaping the modern evolutionary synthesis. His work fundamentally redefined the concept of a species, moving beyond mere morphological similarity to emphasize reproductive isolation. Mayr posited that species are groups capable of interbreeding exclusively among themselves, thereby addressing the long-standing 'species problem.' His theory of peripatric speciation, inspired by his extensive research on birds, remains a leading explanation for how new species arise.
