Ernst Mayer (24 June 1796 [1] – 21 January 1844) was a German sculptor in the classical style. He was a pupil of Antonio Isopi and worked for Leo von Klenze , mainly in Munich where in 1830 he became Professor of Sculpture at the Polytechnic, now the Technical University .

This concept Ernst Mayr proposes here is now commonly referred to as the biological species concept. The biological species concept defines a species in terms of biological factors such as reproduction , taking into account ecology, geography, and life history; it remains an important and useful idea in biology, particularly for animal ...
In 1941, Edgar Anderson (whose work on hybridization in the genus Iris had interested Stebbins since they met in 1930) and Ernst Mayr co-presented the lecture series and Mayr later published his lectures as Systematics and the Origin of Species. In 1946, Stebbins was invited on Dobzhansky's recommendation to present the prestigious lectures.
It was first fully outlined by Ernst Mayr in 1942, [1] using existing theoretical work by those such as Sewall Wright. [2] As a result of the loss of genetic variation, the new population may be distinctively different, both genotypically and phenotypically, from the parent population from which it is derived.
