Various trees of life are recounted in folklore, culture and fiction, often relating to immortality or fertility.They had their origin in religious symbolism. According to professor Elvyra Usačiovaitė, a "typical" imagery preserved in ancient iconography is that of two symmetrical figures facing each other, with a tree standing in the middle.
The term phylogeny for the evolutionary relationships of species through time was coined by Ernst Haeckel, who went further than Darwin in proposing phylogenic histories of life. In contemporary usage, tree of life refers to the compilation of comprehensive phylogenetic databases rooted at the last universal common ancestor of life on Earth .
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).
