Everything You Ever Wanted to Know about E. Coli (2008)

Carl Zimmer, author of "Microcosm: E. coli and the New Science of Life," discusses the significance of E. coli in understanding life. E. coli, a bacterium found in the intestines of warm-blooded animals, plays a crucial role in digestion and maintaining a balanced microbial ecosystem. Zimmer emphasizes that E. coli is not a simple organism; it has around 4,000 genes and is highly evolved, adapting well to its environment. The bacterium's versatility allows it to thrive in challenging conditions, competing with numerous other microbes. Zimmer's interest in E. coli stems from fundamental questions about life and the rules governing living organisms. He notes that E. coli has been pivotal in scientific research, helping scientists explore deep biological questions due to its well-understood genetic makeup. The discussion also touches on the historical context of understanding life, referencing thinkers like Aristotle and physicist Erwin Schrödinger, who pondered the essence of life. Zimmer concludes that while E. coli is often associated with foodborne illnesses, it is also a vital component of human health and a key to understanding biological processes.
