Natural Selection

The video discusses strep throat, antibiotics, and the concept of natural selection using frogs as an example. It explains how variations and mutations occur randomly and can affect an organism's fitness. The video then connects these ideas to antibiotic resistance in bacteria, highlighting the importance of responsible antibiotic use and the development of new antibiotics to combat resistant strains. It concludes with a reminder of the role of vaccines in preventing bacterial infections.
