Website. www.tolweb.org. The Tree of Life Web Project is an Internet project providing information about the diversity and phylogeny of life on Earth. [1][2] This collaborative peer reviewed project began in 1995, and is written by biologists from around the world. The site has not been updated since 2011, however the pages are still accessible.
Tree of life (biology) 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]
Charles Darwin and the Tree of Life. 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 presenter, David Attenborough, outlines the ...
Carl Richard Dick Woese (/ ˈwoʊz /; [3] July 15, 1928 – December 30, 2012) was an American microbiologist and biophysicist. Woese is famous for defining the Archaea (a new domain of life) in 1977 through a pioneering phylogenetic taxonomy of 16S ribosomal RNA, a technique that has revolutionized microbiology. [4][5][6][7] He also originated ...
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.
The eocyte hypothesis in evolutionary biology proposes that the eukaryotes originated from a group of prokaryotes called eocytes (later classified as Thermoproteota, a group of archaea). [1] After his team at the University of California, Los Angeles discovered eocytes in 1984, [2] James A. Lake formulated the hypothesis as "eocyte tree" that ...
The two-domain system is a biological classification by which all organisms in the tree of life are classified into two domains, Bacteria and Archaea. [ 1 ] [ 2 ] [ 3 ] It emerged from development of knowledge of archaea diversity and challenges the widely accepted three-domain system that classifies life into Bacteria, Archaea, and Eukarya . [ 4 ]
OneZoom. 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.
