Charles Darwin's voyage as a naturalist took place on the HMS Beagle in 1831. During this time, Darwin made many observations and collected specimens of plants and animals that would ultimately lead him to develop his theory of evolution through natural selection by observing fossils and illustrate species. -
After his voyage on the HMS Beagle, Charles Darwin returned to England and spent many years studying and analyzing the specimens he had collected during the expedition. He also corresponded with other scientists and experts in various fields, exchanging ideas and knowledge. This made him an established naturalist. -
Charles Darwin and Alfred Russel Wallace met through their mutual interest in the natural world and their shared work on the theory of evolution. In 1858, Wallace wrote to Darwin with his own theory of evolution through natural selection. Wallace's ideas were similar to Darwin's, but the two men had never met, and Darwin was surprised to find that someone else had independently arrived at the same theory he had been working on for years. -
After years of collecting evidence and analyzing his observations, Darwin developed the theory of evolution through natural selection, which he presented in "On the Origin of Species." The book argued that species change over time as a result of natural selection, a process in which organisms with advantageous traits are more likely to survive and reproduce.
