The correct answer is: A. Darwin
Charles Darwin was a British naturalist, geologist and biologist, best known for his contributions to the science of evolution. His proposition that all species of life have descended over time from common ancestors is now widely accepted, and considered a foundational concept in science. In a joint publication with Alfred Russel Wallace, he introduced his scientific theory that this branching pattern of evolution resulted from a process that he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding.
Darwin’s scientific discovery is known as evolution, which is the idea that all species of life have descended over time from common ancestors. This means that all living things are related, and that we share a common history. Evolution is a gradual process, and it can take millions of years for a species to change significantly.
Darwin’s theory of evolution is based on the idea of natural selection. Natural selection is the process by which organisms that are better adapted to their environment are more likely to survive and reproduce. This means that the characteristics that make an organism better adapted to its environment are more likely to be passed on to the next generation. Over time, this can lead to significant changes in a species.
Darwin’s theory of evolution is supported by a wide range of evidence, including the fossil record, the study of comparative anatomy, and the study of embryology. The fossil record shows that species have changed over time, and that the changes have been gradual. The study of comparative anatomy shows that organisms that are closely related share many similarities, while organisms that are distantly related share fewer similarities. The study of embryology shows that the embryos of closely related species are very similar, while the embryos of distantly related species are less similar.
Darwin’s theory of evolution is one of the most important and influential theories in the history of science. It has revolutionized our understanding of life on Earth, and it continues to be a subject of active research.
The other options are incorrect because they do not refer to the person who said that members of the same species are not alike.
