Evolution from a single ancestor is discredited
According to Charles Darwin, life evolved from one common ancestor. Recent scientific work contradicts this expectation. Molecular data indicates that the tree of life should be uprooted and discredits the homology concept.
- Yahya, Harun, n.d. Darwinism Refuted. 
- To quote the concluding sentence of Origin of Species:"There is grandeur in this view of life, with its several powers, having been originally breathed by the Creator into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved." (emphasis added) Clearly, Darwin did not insist on a single common ancestor to all of life. Ergo, this claim must have been made by someone who did not actually read what Darwin had to say on the topic.
- Debate over whether there was a single last common ancestor of all life or a more complex pattern of relation has been ongoing for a long time and is hardly a secret. The validity of evolution does not hinge on any particular outcome in this controversy.
- The portion of Darwinism that deals with the possibility of common descent is the theory of evolution, which is not to be confused with the fact of evolution. That evolution occurs at all is a fact. That it implies common descent is a theory. A theory which is, incidentally, well-supported by all known terrestrial organisms.
