Answer:
Ernst Walter Mayr (/ˈmaɪər/; 5 July 1904 – 3 February 2005)[1][2] was one of the 20th century's leading evolutionary biologists. He was also a renowned taxonomist, tropical explorer, ornithologist, philosopher of biology, and historian of science.[3] His work contributed to the conceptual revolution that led to the modern evolutionary synthesis of Mendelian genetics, systematics, and Darwinian evolution, and to the development of the biological species concept.
Although Charles Darwin and others posited that multiple species could evolve from a single common ancestor, the mechanism by which this occurred was not understood, creating the species problem. Ernst Mayr approached the problem with a new definition for species. In his book Systematics and the Origin of Species (1942) he wrote that a species is not just a group of morphologically similar individuals, but a group that can breed only among themselves, excluding all others. When populations within a species become isolated by geography, feeding strategy, mate choice, or other means, they may start to differ from other populations through genetic drift and natural selection, and over time may evolve into new species. The most significant and rapid genetic reorganization occurs in extremely small populations that have been isolated (as on islands).
His theory of peripatric speciation (a more precise form of allopatric speciation which he advanced), based on his work on birds, is still considered a leading mode of speciation, and was the theoretical underpinning for the theory of punctuated equilibrium, proposed by Niles Eldredge and Stephen Jay Gould. 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.

Abstract
AbstractHere, I attempt to explore the interactions between evolutionary biologist Ernst Mayr and other biologists in the process that has been called the professionalizing of evolutionary biology, and in the defence of organismal biology and of systematics. I will use the tool of quoting from original writings rather than paraphrasing them, since it is necessary to preserve the flavour of the arguments and controversies that Mayr was involved in, and that led to Mayr's role in helping to build the edifice of evolutionary biology as it is known today.

The journal covers all branches of pure/applied science and technology such as physics, chemistry, life sciences, medicine, earth sciences, engineering and technology. Full length research articles and shorter research communications, review articles, scientific correspondence and commentaries, news and views, comments on recently published research papers, articles on universities and institutions, interviews with scientists, , book reviews, etc are published in the journal. Special Sections are also published on diverse and topical themes and this has served as a platform for scientific fraternity to get their work acknowledged and highlighted. The Editorial Board consists of experts from India and abroad in all scientific disciplines.
