The Shape-Shifting Cells Inside You

You might think amoebas are a unique creature, but they are actually a survival strategy found in every major life form. Even parts of your own body use these flowing, shape-shifting movements to survive.

An amoeba is not a single species, but rather a universal way for a cell to move and eat by stretching out temporary limbs called pseudopods. This ability is so efficient that it evolved independently in fungi, algae, and even within the complex bodies of animals. In humans, certain white blood cells use this exact mechanism to crawl through your tissues and hunt down invaders. It is a fundamental trick of nature that persists across all branches of the tree of life.
