Document Summary
Why study this: simple beginnings they are, low complexity. Simple biological machines are not that simple: fossil found 3. 7b years. Using fossil records, we can understand how life started: the diversity of life. We have 3-5 pounds of bacteria mainly in the guts. Taking antibiotics sometimes have consequences that affect those 3-5 pounds of your bacteria: microbiology and immunology are linked. We have highly evolved immune system but so other organisms. History of microscopy: know the discovery but not the dates. He wanted to know if you can see microorganism. His lens got magnified and seen (wee animalcules). Edward jenner: small box was a major threat. Small box: the foundation of vaccination used jenner work. He took a scraping from a cow and deliberately infected a child. The concept if immunity was born and have a response and not get a full disease.
