Ernst Mayr approached the problem with a new definition for the concept of species.

Mayr is sometimes credited with inventing modern philosophy of biology, particularly the part related to evolutionary biology, which he distinguished from physics due to its introduction of ( natural ) history into science.

Stresemann was very impressed and suggested that, between semesters, Mayr could work as a volunteer in the ornithological section of the museum.

Mayr wrote about this event, " It was as if someone had given me the key to heaven.

" Mayr was endlessly interested in ornithology and " chose Greifswald at the Baltic for my studies for no other reason than that ... it was situated in the ornithologically most interesting area.

" During the first semester break Stresemann gave him a test to identify treecreepers and Mayr was able to identify most of the specimens correctly.

Mayr completed his doctorate in ornithology at the University of Berlin under Dr. Carl Zimmer, who was a full professor ( Ordentlicher Professor ), on June 24, 1926 at the age of 21.
