New and stronger diseases occur when viruses, bacteria, and fungi evolve. Because organisms like bacteria and viruses reproduce much faster than humans they are able to evolve must faster than humans as well. Below are a few videos that show how these organisms evolve. 

If you understand how bacteria and viruses evolve then you are ready for the next assignment. Fill out the explanation tool below to explain how antibiotic resistance evolves in bacteria. Submit a photo of the filled out tool to the next page in the module.
