Various strains of the Staphylococcus genus of spherical bacteria thrive on the skin. Of these, Staphylococcus epidermis is the generally found skin bacterium. It is most commonly found in sweaty places like in forearms and armpits. Staphylococcus epidermis thrives on the skin of each and every human being.
In combination with other microbes, they generate components from sweat and produce a body odor related to perspiration. These bacteria like other species of Staphylococci combine together in the form of grapes bunches. The Staphylococcus epidermis protects the body from destructive bacteria like Staphylococcus aureus.
All adaptations begin as a genetic mutation because these adaptations passed from one generation to another generation through genes of that organisms. Organisms that are adapted to their environments and survive more better, it will produce more offspring in which that genetic characteristics are transmitted from the parents so we can say that genetic mutation is responsible for adaptations.
