The tree of life or universal tree of life is a metaphor, conceptual model, and research tool used to explore the evolution of life and describe the relationships between organisms, both living and extinct, as described in a famous passage in Charles Darwin's On the Origin of Species (1859). [1]
In Hermetic Qabalah, the Tree of Life is a fundamental concept and symbol that represents the structure of the universe and the spiritual and metaphysical path to enlightenment. It is often depicted as a diagram composed of ten interconnected spheres (called sephiroth) and 22 connecting paths, which together form a pattern resembling a tree.
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).
A tree of life, like this one from Charles Darwin's notebooks c. July 1837, implies a single common ancestor at its root (labelled "1"). A phylogenetic tree directly portrays the idea of evolution by descent from a single ancestor. [3] An early tree of life was sketched by Jean-Baptiste Lamarck in his Philosophie zoologique in 1809.
In the Book of Proverbs, the tree of life is associated with wisdom: "[Wisdom] is a tree of life to them that lay hold upon her, and happy [is every one] that retaineth her."

the entire Tree of Life is contained in each of the four worlds; in this manner, they are described as one on top of another and in symbolic form by a diagram called Jacob's Ladder. The Tree of Life can be subdivided into four horizontal sections, each representing one of the four worlds. In Kabbalah, each of the ten sefirot of the Tree of Life ...
The OneZoom Tree of Life. The OneZoom Tree of Life Explorer is a web-based phylogenetic tree software. It aims to map the evolutionary connection of all known life. As of 2023 it includes over 2.2 million species. [1] [2]
In Judaism and Christianity, the tree of life (Hebrew: עֵץ הַחַיִּים, romanized: ‘ēṣ haḥayyīm; Latin: Lignum vitae) [1] is first described in chapter 2, verse 9 of the Book of Genesis as being "in the midst of the Garden of Eden" with the tree of the knowledge of good and evil (עֵץ הַדַּעַת טוֹב וָרָע; Lignum scientiae boni et mali).
