In many countries, it was issued as the second single from the album, in February , becoming a top-ten hit in the United States, Canada and elsewhere, and topping singles charts in Australia and Switzerland. Harrison co-produced the recording with Phil Spector , whose Wall of Sound production also employed a prominent string arrangement by John Barham and multiple acoustic rhythm guitars, played by Harrison's fellow Apple Records signings Badfinger. An uptempo composition in the soul genre, "What Is Life" is one of several Harrison love songs that appear to be directed at both a woman and a deity. Built around a descending guitar riff , it is one of Harrison's most popular compositions and was a regular inclusion in his live performances. Rolling Stone magazine has variously described it as a "classic"  and an "exultant song of surrender".

Difference between Lamarckism and Darwinism ( words)
Evolutionary thought, the recognition that species change over time and the perceived understanding of how such processes work, has roots in antiquity—in the ideas of the ancient Greeks , Romans , and Chinese as well as in medieval Islamic science. With the beginnings of modern biological taxonomy in the late 17th century, two opposed ideas influenced Western biological thinking: essentialism , the belief that every species has essential characteristics that are unalterable, a concept which had developed from medieval Aristotelian metaphysics , and that fit well with natural theology ; and the development of the new anti-Aristotelian approach to modern science : as the Enlightenment progressed, evolutionary cosmology and the mechanical philosophy spread from the physical sciences to natural history. Naturalists began to focus on the variability of species; the emergence of paleontology with the concept of extinction further undermined static views of nature. In the early 19th century Jean-Baptiste Lamarck — proposed his theory of the transmutation of species , the first fully formed theory of evolution. Unlike Lamarck, Darwin proposed common descent and a branching tree of life , meaning that two very different species could share a common ancestor. Darwin based his theory on the idea of natural selection : it synthesized a broad range of evidence from animal husbandry , biogeography , geology , morphology , and embryology.

August Friedrich Leopold Weismann studied how the traits of organisms developed and evolved in a variety of organisms, mostly insects and aquatic animals, in Germany in the late nineteenth and early twentieth centuries. Weismann proposed the theory of the continuity of germ-plasm, a theory of heredity. Weismann postulated that germ-plasm was the hereditary material in cells, and parents transmitted to their offspring only the germ-plasm present in germ-cells sperm and egg cells rather than somatic or body cells. Weismann also promoted Charles Darwin 's theory of the evolution of species.
