What does that have to do with it? All that supports is that all living creatures probably have a common origin.
All living creatures probably have neither a common origin, nor a common ancester, unless you count the entire pre-biotic universe as the common origin. You don't know what you are talking about; you are making up your own version of science as you go along, and you don't appear determined to repair that. The three of life does not terminate in a single node--it branches like the roots of real tree. Please leave me alone until you show some sign that you know at least something about the science you think you are attacking. Natural abiogensis stands on a similar sort of evidence of gradual change, evaluated in the same inductive manner, as natural evolution--or do you, unlike Behe and Dembski, the stars of the ID movement, deny evolutionary theory as well?
