One of the first popular science books, the intent of "The Botanic Garden" is to pique readers' interest in science while educating them at the same time. By embracing Linnaeus's sexualized language, which plants, Darwin intended to make botany interesting and relevant to the readers of his time. Darwin emphasizes the connections between humanity and plants, arguing that they are all part of the same natural world and that sexual reproduction is at the heart of evolution (ideas that his grandson, Charles Darwin, would later turn into a full-fledged theory of evolution). This evolutionary theme continues in "The Economy of Vegetation" which contends that scientific progress is part of evolution and urges its readers to celebrate inventors and scientific discoveries in a language usually reserved for heroes or artistic geniuses. Darwin's attempt to popularize science and to convey the wonders of scientific discovery and technological innovation through poetry helped initiate a tradition of popular science writing that continues to the present day.
