On Natural Selection - Brossura

Charles Robert Darwin was born in 1809 in Shrewsbury, England, to a wealthy intellectual family, his grandfather being the famous physician Erasmus Darwin. At Cambridge University he formed a friendship with J. S. Henslow, a professor of botany, and that association, along with his enthusiasm for collecting beetles, led to “a burning zeal,” as he wrote in his Autobiography, for the natural sciences. When Henslow obtained for him the post of naturalist on H.M.S. Beagle, the course of his life was fixed. The five-year-long voyage to the Southern Hemisphere between 1831 and 1836 would lay the foundation for his ideas about evolution and natural selection. Upon his return Darwin lived in London before retiring to his residence at Down, a secluded village in Kent. For the next forty years he conducted his research there and wrote the works that would change human understanding forever. Knowing of the resistance from the orthodox scientific and religious communities, Darwin published The Origin of Species in 1859 only when another naturalist, Alfred Russel Wallace, independently reached the same conclusions. His other works include The Descent of Man, and Selection in Relation to Sex (1871) and Recollections of My Mind and Character, also titled Autobiography (1887). Charles Darwin’s Diary of the Voyage of the H.M.S. Beagle was published posthumously in 1933. Darwin died in 1882; he is buried in Westminster Abbey.

Struggle for Existence

Nothing is easier than to admit in words the truth of the universal struggle for life, or more difficult - at least I have found it so - than constantly to bear this conclusion in mind. Yet unless it be thoroughly engrained in the mind, I am convinced that the whole economy of nature, with every fact on distribution, rarity, abundance, extinction, and variation, will be dimly seen or quite misunderstood. We behold the face of nature bright with gladness, we often see superabundance of food; we do not see, or we forget, that the birds which are idly singing round us mostly live on insects or seeds, and are thus constantly destroying life; or we forget how largely these songsters, or their eggs, or their nestlings, are destroyed by birds and beasts of prey; we do not always bear in mind, that though food may be now superabundant, it is not so at all seasons of each recurring year.

I should premise that I use the term Struggle for Existence in a large and metaphorical sense, including dependence of one being on another, and including (which is more important) not only the life of the individual, but success in leaving progeny. Two canine animals in a time of dearth, may be truly said to struggle with each other which shall get food and live.
