It is curious to ponder the evolution of the human animal - or of most any other animal for that matter - but human evolution is especially interesting. Why? Because some of our physical characteristics - even some of our basic senses - have degraded in deference to the hyper-evolution of the brain. For instance, the human ability to sense smell is much reduced as compared to most other animals. Yet, it is that sense to which we ascribe a great deal of importance. This is evidenced by the billions of dollars that are spent every year on fragrance, perfume, deodorant (to un odor ourselves?) and other methods of masking or enhancing our natural smell. Is it the overly developed human brain that makes us wash off the natural scent of our bodies, then sprinkle new artificial scents onto ourselves? A what drives the basic logic behind the characteristics of a good vs. bad scent? Flowers smell good. Rotting flesh smells bad. These connections to smell evolved over millions of years, but at the same time the basic ability to detect scent has degraded. Are we more dependent on sight? Perhaps. Hearing? Maybe, but most animals hear much better than we do. Or is it that the human mind is better able to take the weak signals that our senses have become and combine them more efficiently than any other animal is capable?
