How Nature’s Symmetry Might Help Us See Early Warning Signs of Cancer
Have you ever wondered why animals and humans often have pairs of body parts — like two eyes, two ears and two nostrils? The short answer is that having mirrored sense organs helps us understand our surroundings better.
For example, your eyes sit a little apart, giving your brain two slightly different views. By comparing them, your brain figures out how far away objects are — this is what we call depth perception. Similarly, two ears pick up sounds at slightly different times, which helps you figure out where a sound is coming from.
