caption_attribution_description: English: Stock #7465800 (purchased and donated by Kosi Gramatikoff User:Kosigrim) Haeckel's Paleontological Tree of Vertebrates (c. 1879).The evolutionary history of species has been described as a "tree", with many branches arising from a single trunk. While Haeckel's tree is somewhat outdated, it illustrates clearly the principles that more complex modern reconstructions can obscure.
context_page_description: The timeline of human evolution outlines the major events in the evolutionary lineage of the modern human species, Homo sapiens,
  throughout the history of life, beginning some 4 billion years ago down to recent evolution within H. sapiens during and since the Last Glacial Period.
  It includes brief explanations of the various taxonomic ranks in the human lineage. The timeline reflects the mainstream views in modern taxonomy, based on the principle of phylogenetic nomenclature;
  in cases of open questions with no clear consensus, the main competing possibilities are briefly outlined.
