Stratosphere is the majority of Ozone that protects against the high energy radiation of the sun. Ozone is an allotrope of oxygen. It is the necessary protective component of upper atmosphere but considered a pollutant in the atmosphere.

In troposphere temperature increases with increasing ltitude. Ozone was discovered in 1913 by French Physicists called Henri Buisson and Charles Fabry. 97 TO 99 percent of sun’s medium-frequency ultraviolet light are absorbed on the Ozone layer.

Cladistics is concerned with entire branchings. This way groups all the descendants from a common radiation into a clade as a related group and no others. The clades are monophyletic. This is a narrower definition of an older, less precise concept.

Phylogeny is a way of tracking evolutionary relationships based on shared characters. Originally this used Linnaeus' artificially defined levels of taxonomy. This method allows convergent characters to be grouped despite their having followed a separate evolutionary path. Taxonomy is the rank levels while phylogeny is the path through the ranks.

Cladistics is a way of grouping the related branches based on sharing derived characters within the group. However these characters are not found in other species except by convergence.
