Why the human body has so many design flaws

The article delves into how many of our body's imperfections stem from evolutionary history, where old designs were gradually adapted rather than entirely overhauled. This explains why we have vulnerable spines, prone teeth, and other structures that, while functional enough for survival, often lead to pain or disease today. The persistence of seemingly useless features like the appendix further highlights how evolution prioritizes survival over optimal design. This insight underscores that our bodies are a testament to millions of years of adaptation rather than a blueprint for perfection.
