Quote by Kenneth Chang, In Explaining Lif
At the heart of the debate over intelligent design is this question: Can a scientific explanation of the history of life include the actions of an unseen higher being? The proponents of intelligent design, a school of thought that some have argued should be taught alongside evolution in the nation's schools, say that the complexity and diversity of life go beyond what evolution can explain.Biological marvels like the optical precision of an eye, the little spinning motors that propel bacteria and the cascade of proteins that cause blood to clot, they say, point to the hand of a higher being at work in the world.http://www.nytimes.com/2005/08/22/national/22design.html
Summary
The quote highlights the core question in the debate on intelligent design - whether a scientific explanation of the history of life can account for the actions of an unseen higher being. Proponents of intelligent design argue that the complexity and diversity of life surpass the explanatory limits of evolution. They point to biological marvels, such as the precision of the eye and the intricate mechanisms within living organisms, as evidence of a higher being's involvement in the world.
