The branches indicate the different lineages that diverged from a common ancestral species. The taxa represent the various genera under the family Felidae that evolved from a common ancestor. WebThis pattern repeats as one goes through the phylogenetic tree of life: A change in an organism’s genetic makeup leads to a new trait which becomes prevalent in the group. Many organisms descend from this point and have this trait. New variations continue to arise: some are adaptive and persist, leading to new traits.

The idea of a tree of life arose from ancient notions of a ladder-like progression from lower into higher forms of life (such as in the Great Chain of Being). Early representations of "branching" phylogenetic trees include a "paleontological chart" showing the geological relationships among plants and animals in the book Elementary Geology, by Edward Hitchcock (first edition: 1840).
