If "Beauty is in the eye of the beholder" then humans see the world with the eyes of a fruit lover.
Fruits, a type of food that is both beautiful to look at and nourishes the body as a source of nutrition, it can be seen that our natural attraction to the appearance and beauty of fruits is always linked to it being our natural diet. A sign of our natural diet is that it is a food that we are certainly attracted to in its raw and completely unprocessed state. It is often said that humans are natural omnivores, but I think our attraction to the physical beauty of fruit is something that suggests that we are actually fruit-eating by design. We are attracted to fruit by its appearance when it is ripe and ready for us to eat in its pure, whole, unadulterated state.
Fruit trees make their fruit have an attractive shape and smell that attracts us to pick the fruit and then spread the precious seeds inside. The vibrancy and beauty of fruit has a purpose to seduce. Just as the color and fragrance of flowers attract insects to pollinate the flowers, the attractive color and appearance of fruit ensures that humans and other fruit-loving creatures can easily find it as soon as it ripens. The shape and size of fruits vary greatly, from the small, smooth sphere of the carom seed to the oval shape of the custard apple seed. The diversity of fruit shapes and sizes adds to their diverse beauty. Another way to see the beauty of fruit is to look at it in a different way, by cutting or slicing the fruit and looking at the geometric shape of the cross sections. Some fruits really attract us with their colorful skin, rough or smooth surface that amazes and delights us with their vibrancy.
