Evolutionary Tree

[Esquilax]

However, if some genes say we are related to chimpanzees and some genes say we are not, and that conflict is not resolved, that would significantly weaken the theory of common decent. My point was and continues to be that if common decent is called into question in the long run, every other part of the overall Theory of Evolution (modern synthesis) that is not an observable fact (in the strong sense of the word) is undermined (which is most of it).

So your point is one huge argument from ignorance. Gotcha.
