The arrangement of two eyes and two ears, as opposed to one nose and one mouth, is largely related to the functions and benefits each sensory organ provides.
Two Eyes:
Having two eyes provides several advantages, such as depth perception, better peripheral vision, and a wider field of view. These features are crucial for tasks like judging distances, detecting motion, and navigating the environment effectively. Binocular vision, where both eyes work together, enhances our ability to perceive the three-dimensional world around us.
Two Ears:
Similarly, having two ears allows humans and many animals to localize the source of sounds. The slight time delay it takes for a sound to reach one ear compared to the other, along with the difference in intensity, helps us determine the direction from which the sound is coming. This is essential for survival, as it helps us detect potential threats and communicate effectively in social situations.
One Nose and Mouth:
The nose and mouth serve different functions compared to eyes and ears. The nose is primarily responsible for smelling and filtering the air we breathe, while the mouth is involved in tasks such as eating, speaking, and breathing. While having two nostrils can aid in detecting the direction of certain smells, the primary function of the nose is to process and filter air, rather than spatial perception like the eyes or ears.
The arrangement of sensory organs is ultimately determined by the specific functions they serve and the evolutionary advantages they provide for survival and adaptation to the environment.
In summary, we have two eyes so that we can see twice than talk as well as listen. The more we talk the more we make mistake, the more we see and hear the more we reduce the mistake. That's why.
