Question
How has Darwin's research affected the development and organization of plants and animals?
The concept of evolution by natural selection is central to the biological sciences, as fundamental as Newton's laws of motion and of gravity are to physics, or plate tectonics is to geology. If this is what you are asking, then certainly Darwinian evolution represents one of the triumphs of human intelligence, a concept that allows scientists to make sense out of the otherwise bewildering diversity of the living world (as well as practical offshoots, such as modern pharmaceuticals). If you are literally asking how Darwin's research affected the development and organization of plants and animals, then the answer of course is not at all. Biological evolution has been taking place on earth for 4 billion years, and it will continue in the future, whether Darwin had lived or not. Darwin did not influence evolution, but he played a key role is developing our understanding of evolution and hence of the relationships among all living things on Earth.
