Things Aren’t So Simple As They Once Seemed

In Darwin’s time, living cells and light-sensitive spots were thought to be simple structures. With the help of electron microscopes, modern microbiologists have learned that both are enormously complex structures, and that our bodies contain “irreversibly complex mechanisms” whose several parts have no other function than to act as part of a goal-directed system. The cell has now been described as more complex than a nuclear submarine or a small city. Harvard University has produced an amazing video that describes the reactions that take place in our body’s cells when inflammation occurs. Here is that video.
