Skin is a barrier that serves as one of the body's first lines of defense against harmful microbes. Specialized immune cells within skin tissue help to fight invading organisms. Past work by an NIH research team showed that commensals can help the body's immune cells fight disease-causing microbes.

Genetic connections are used to help place organisms on a cladogram. This can be explained in the following manner:-
Cladograms are branching diagrams in which every branch denotes an evolutionary ancestry i.e. a clade. They are utilized to depict the hypothesized order of divergence among organisms and common ancestors.
Cladograms are arranged systematically through genetic connections. They are tree-shaped diagrams which portray the evolutionary links that are present between living organisms.
They are structured by comparing the genetic information of dissimilar organisms. The organisms which share very similar genes are, to a greater extent closely related, in contrast to those who possess very dissimilar genes.
