Gotta add my bit! I reckon gravity isn't a theory - it's a natural phenomenon. THEORIES of gravity are theories. e.g. Einstein's theory of general relativity is a theory and Newton's theory is a theory. Ta - sorry - i'll go back into my hole now.

In genetic genealogy there are a lot of theories, and genetic genealogy, although dependent on the science aspect in terms of the Y, mt, and at DNA's, in itself is not by its very nature a pure scientific discipline. It is married to a rather unscientific discipline, genealogy, albeit, that some attempt to apply the scientific method to; but defies the rigors of it. With all theory there are uncertainties; and some theories go unchallenged for lack of enough concrete evidence and/or considerable contradictory evidence by which to prove a theory "wrong". Walter, you are correct, there is no proving theory in the strictest sense; however there are better arguments than others, and sloppy and manipulated foundations for drawing conclusions does not equate with sound conclusions. Some to many go unchallenged, are simply ignored, or there is no debate as they are dismissed out-right. Others, however, titillate the emotion of the public that doesn't consider, in many cases, fact from fiction, pick up on them and run because someone said so. :-D For the greater part, those of us in this hobby as accomplished as some are, yet are the public; and those who haven't made up their minds running with the theories are still trying to figure out their own.

Hi All, I spent years of my life in institutes of technology including MIT. Yeah, we all know about gravity and its effects can be calculated, but nobody has yet been able to prove just how and why it exists. It is nice to have facts to work with, but apparently some things remain theoretical. For instance, just what could those big black holes in outer space be? Ooooo, could they be Earth gobbling monsters? Yeah, there are those things that we can observe but cannot explain.
