A statement by the Royal Society on evolution, creationism and intelligent design
.
The Royal Society was founded in 1660 by a group of scholars whose desire was to promote an understanding of ourselves and the universe through experiment and observation. This approach to the acquisition of knowledge forms the basis of the scientific method, which involves the testing of theories against observational evidence. It has led to major advances of understanding over more than 300 years. Although there is still much left to be discovered, we now have a broad knowledge of how the universe developed after the 'Big Bang' and of how humans and other species appeared on Earth.
One of the most important advances in our knowledge has been the development of the theory of evolution by natural selection. Since being proposed by Charles Darwin nearly 150 years ago, the theory of evolution has been supported by a mounting body of scientific evidence. Today it is recognised as the best explanation for the development of life on Earth from its beginnings and for the diversity of species. Evolution is rightly taught as an essential part of biology and science courses in schools, colleges and universities across the world.
The process of evolution can be seen in action today, for example in the development of resistance to antibiotics in disease-causing bacteria, of resistance to pesticides by insect pests, and the rapid evolution of viruses that are responsible for influenza and AIDS. Darwin's theory of evolution helps us to understand these problems and to find solutions to them.
Many other explanations, some of them based on religious belief, have been offered for the development of life on Earth, and the existence of a 'creator' is fundamental to many religions. Many people both believe in a creator and accept the scientific evidence for how the universe, and life on Earth, developed. Creationism is a belief that may be taught as part of religious education in schools, colleges and universities. Creationism may also be taught in some science classes to demonstrate the difference between theories, such as evolution, that are based on scientific evidence, and beliefs, such as creationism, that are based on faith.
However, some versions of creationism are incompatible with the scientific evidence. For instance, a belief that all species on Earth have always existed in their present form is not consistent with the wealth of evidence for evolution, such as the fossil record. Similarly, a belief that the Earth was formed in 4004 BC is not consistent with the evidence from geology, astronomy and physics that the solar system, including Earth, formed about 4600 million years ago.
Some proponents of an alternative explanation for the diversity of life on Earth now claim that their theories are based on scientific evidence. One such view is presented as the theory of intelligent design. This proposes that some species are too complex to have evolved through natural selection and that therefore life on Earth must be the product of a 'designer'. Its supporters make only selective reference to the overwhelming scientific evidence that supports evolution, and treat gaps in current knowledge which, as in all areas of science, certainly exist - as if they were evidence for a 'designer'. In this respect, intelligent design has far more in common with a religious belief in creationism than it has with science, which is based on evidence acquired through experiment and observation. The theory of evolution is supported by the weight of scientific evidence; the theory of intelligent design is not.
Science has proved enormously successful in advancing our understanding of the world, and young people are entitled to learn about scientific knowledge, including evolution. They also have a right to learn how science advances, and that there are, of course, many things that science cannot yet explain. Some may wish to explore the compatibility, or otherwise, of science with various religious beliefs, and they should be encouraged to do so. However, young people are poorly served by deliberate attempts to withhold, distort or misrepresent scientific knowledge and understanding in order to promote particular religious beliefs.
