After watching the entire video it’s hard to believe that she can talk about organisms changing but not see that she was saying that they evolved. Just because she doesn’t see bacteria evolve into fruit flies doesn’t mean they haven’t evolved. The existance of something like MRSA is to me some of the biggest proof of evolution. These organisms evolved from less lethal forms of bacteria, or at least forms that were not so resistant to antibiotics. The stress on their population was probably the antibiotics we use. The result is bacteria that is very resistant to antibiotics. That’s why we need to keep coming up with different antibiotics and the ones from 20 years ago don’t work as well.
