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).
Charles Darwin and the Tree of Life is a 2009 television documentary about Charles Darwin and his revolutionary theory of evolution through natural selection, produced by the BBC to mark the bicentenary of Darwin's birth. It is part of the BBC Darwin Season.
The tree of life should perhaps be called the coral of life, base of branches dead; so that passages cannot be seen — Charles Darwin [ 1 ] with obvious reference to branching corals whose dead colonies may form very thick deposits in the ocean ( representing past life ) with live animals occurring only on the top ( recent life ).

On the Origin of Species (or, more completely, On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life) [3] is a work of scientific literature by Charles Darwin that is considered to be the foundation of evolutionary biology. It was published on 24 November 1859. [4]
Priceless notebooks belonging to Charles Darwin have been mysteriously returned to Cambridge University more than 20 years after they went missing. Darwin's missing 'tree of life' notebooks ...
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.
Charles Darwin was probably right when he suggested all life on Earth started in a “primordial soup.” Scientists continue to find evidence of the theory.
