Hair, Fur and Style
Hairs, now 220 million years old, are a characteristic of mammals. In humans, the naked apes, they are more likely a remnant of evolution. Either they grow too sparsely, or too much, and then often in the wrong places. As scalp hair, they are often expression of animalistic inferiority complexes.
So, let us remain with the animals and their dermatological excesses. Hair is mainly made up of keratin. A hedgehog's spines are modified hair, and a rhinoceros horn is actually hair, but what a kind of. Hair not only protects against ultraviolet light or rain, it is used for insulation and heat regulation, but it is also camouflage, and finally, a social statement. Animals display an extraordinary diversity of coiffures, furs, and styles. They all show us that we humans are far away from this kind of evolutionary creativity.
