What is intelligent design?

Intelligent Design is the belief that certain features of the universe and living things are best explained by an intelligent cause, not by an undirected process such as natural selection. Proponents argue that complex biological structures exhibit signs of purposeful arrangement, which they interpret as evidence of design. However, Intelligent Design is not widely accepted within the mainstream scientific community, as it does not adhere to the standard methods of scientific inquiry and is often considered a form of creationism.
