The author-editor used excerpts from the works of the greatest scientists and philosophers, letters and diaries, brief biographies, articles by journalists, as well as memoirs of contemporaries and fragments of literary works. And what unites all this substantive diversity? Of course, biology, particularly one of the greatest discoveries made in science in the first half of the 19th century, which transformed the understanding of life, its origin and development.
