Good heavens, no. But I'd say 150 years without a contradicting fact makes a good trend line.
There are always controversies at the fringe of understanding, and, I suppose, always the possibility that the findings will point away from "random" variation.
I just doubt it, and if it isn't "random" it will follow known laws of chemistry and physics.
I concur. At least insofar as we are talking about changes beginning at some point in the middle of the process and continuing to the present.
I suppose the matter of the "beginning of life" may not "follow known laws of chemistry and physics"- but, that is not a question that evolution purports to address, correct?
