I do not claim to know what she said, but I am familiar with the so-called "evidence against evolution" which ID-ists routinely demand be taught in school alongside the actual body of biological science. The description of her talk sounds mightily like something from this same body of cult literature.
There ARE stupid questions, and this is the problem, whether she should be teaching in the very area where she is unable to demonstrate critical thought. An astrologer or a flat-earther may certainly question modern astronomy, but do you want your aspiring-astronomer child to be taught astronomy by such a naysaying dolt?
Bryson said that following the presentation, a senior professor of biology told her she was unqualified and not a professional biologist, and said her presentation was "religion masquerading as science."
She has a case if this guy is simply lying, but it seems unlikely that she gave anything other than the standard Discovery Institute claptrap: " ... a presentation titled 'Critical Thinking on Evolution' -- which covered alternate views to evolution such as intelligent design."
