In Brief:
Mayr, Ernst (1904-2005) was a German-born American biologist who helped develop the synthetic theory of evolution, which combines evolution theory with genetics and other sciences. By 1925, Mayr had decided to devote himself to zoology. In 1928, a top British zoologist invited Mayr to undertake an ornithological expedition to a remote area of western New Guinea. Mayr arrived there in April and explored the bird life of three mountain ranges. In 1928-1929, Mayr undertook a New Guinea expedition to the Saruwaged mountains and Herzog mountains.
