Question

In which year 'Mayer' was awarded by the international prize of biology:-
A 1983
B 1997
C 1994
D 1999

Answer 1

Hint Ernst Mayr, full name Ernst Walter Mayr, was a German-born American biologist who worked on avian taxonomy, population genetics, and evolution. He was born on July 5, 1904, in Kempten, Germany, and died on February 3, 2005, in Bedford, Massachusetts, United States. He was dubbed the "Darwin of the 20th century" since he was one of the world's premier evolutionary biologists.

Complete step by step answer:
Ernst Mayr tackled the challenge by inventing a new species definition. He claimed in his book Systematics and the Origin of Species (1942) that a species is a group of morphologically identical individuals that can only mate among themselves, excluding all others.
When populations within a species become isolated due to geography, foraging strategy, partner choice, or other factors, they may begin to diverge from other populations due to genetic drift and natural selection, evolving into new species over time. Extremely tiny populations that have been isolated have the most substantial and fast genetic rearrangement.
His early research on a species' potential to separate or splinter into daughter species (speciation) and populations founded by a limited number of founders (founder populations) made him a pioneer in the development of the contemporary synthetic theory of evolution.
In the year 1994, Ernest Mayr received the world prize for biology in the subject of Systematic Biology and Taxonomy.

As a result, the correct answer is '1994'.

Note: His notion of peripatric speciation, a more precise variant of allopatric speciation based on his work with birds, is still considered a leading mode of speciation, and constituted the theoretical framework for Niles Eldredge and Stephen Jay Gould's theory of punctuated equilibrium.
