Evolutionary biologist Paul Ewald drags us into the sewer to discuss germs. Why are some more harmful than others? How could we make the harmful ones benign? Searching for answers, he examines a disgusting, fascinating case: diarrhea.
Is anyone concerned that as far as I can tell Dr. Paul Ewald hasn’t published any original resarch in years. Great stump speech though. Sort of like Robert Hooke guessing at the answer and being outed by Newton for not having done the work. Wallace also was guessing without all the groundwork before Darwin. I heard a lecture on itunes and then was dismayed to find it was a decade or more of essays without any original research on his part.
tr, I can’t speak to Dr. Ewald’s qualifications, but why should someone have to be doing original research to be able to communicate science?
This reminds me, I haven’t eaten my probiotic yogourt today.
