and it seems to me that when the latest evo evidence is heralded in the press, that there is little , if any, qualification about it being tentative

That's right, there won't be. Evidence is evidence. Conclusions from evidence may be tentative. Which is an entirely different matter. Not just that, I expect the evidence to be reported, not heralded.

Hey, pete, how does it feel to be basking proudly in the warm glow of deliberately-inflicted pig-ignorance, surrounded by decent, honest scientists who you so studiously ignore?
