| The way an animal smells depends on a lot of factors. Some have musk glands and my experience has been that these animals like to "mark" things (possibly people) with these secretions (skunks do this). Certain bacteria feed on dead skin and sweat and produce a stinky gas, as a by-product. That is one factor that usually makes humans stink. Diet plays a big role (bigger than most realize) in odors. The example that comes to mind first is that of garlic. Food by-product gas also has its own odors. . . Also, there is a line of evolutionary reasoning that says that we humans have aversions to the odor of some types of excrement (more than others) because that type of excrement has more potential to carry organisms that are pathogenic to us. Empirical evidence that seems to support this hypothesis has been experienced by most of us when we've had or been around someone with stomach flu and the odor inspired us to rapidly leave the area. So, while the odors themselves may be harmless, our noses and minds may actually associate them with an alarm or repulsion response to help us avoid danger of infection. This completes my scatology report, and I won't be here, if anyone tries to troll me about it. I'm sorry if this topic bothered anyone!! |
