Intelligent Design is the belief that certain features of the universe and living things are best explained by an intelligent cause rather than an undirected process like natural selection. Proponents argue that the complexity and functionality of biological systems indicate a purposeful design by a higher power, often associated with God or a Creator. This perspective contrasts with the scientific theory of evolution, which explains the diversity of life through natural processes. Supporters of Intelligent Design often cite examples from biology and cosmology to argue that some phenomena cannot be adequately explained by current scientific understanding alone.
