Common descent

A group of organisms is said to have common descent if they have a common ancestor. In biology, the theory of universal common descent proposes that all organisms on Earth are descended from a common ancestor or ancestral gene pool.{{ref|transfer}}

Relevance to creationism

Some creationists do not accept the theory of universal common descent, arguing that humanity was created by God in a distinct act of creation, whereas the rest of life evolved. Other creationists believe that God created many different forms of life and that evolution and speciation has subsequently occurred within some of these forms (as described in creation biology). Still others reject all forms of evolution, arguing that similar structures merely point to a Common Creator, who (purposely) designed the DNA code to be used (almost) universally. Similar to how we use the circle and sphere for so many different purposes (i.e. Wheels, ball bearings, door knobs, stereo knobs, mouse balls, etc.). These last Creationists also believe that each species was individually created.
