    Germs are found on almost every surface we come in contact with, which makes it incredibly common for our bodies to be exposed to them. But why are some of these germs relatively harmless, while others can be fatal? Yannay Khaikan and Nicole Mideo explore this question by examining germs’ varying modes of transmission.

      I felt like it was a a nice overview of the trade-off hypothesis, which I didn't know about. It gave a nice, understandable description of the evolutionary pressures behind virulence and transmission and possible implications.

      Zebras are the best doctors. Most of the time they don't sneeze on people just so they would have to visit the doctor(them) like this greedy bear. ;)

      Germs don't evolve that's already been proven (insert ridiculous Christian "science" website link here). As I have proven that my research has been extensive and that I use words as I choose with utter disregard for their meaning. 😉

    What I don't like about this immediately is that they say that you can feel the mucus land on you - that's misleading. Often you don't FEEL anything at all - and you can still get sick!
