Phylogeny facts for kids
A phylogeny is a proposal of how organisms are related by their evolutionary history.p336 It is based on the evidence that all living things are related by common descent. The evidence for phylogeny comes from palaeontology, comparative anatomy, and DNA sequence analysis.
The main product of phylogenetics is a phylogenetic tree or tree of life. This is a diagram showing a pattern of ancestor/descendent relationships. Information may be related to geological periods or estimated dates. A biological classification is another type of product.

Rooted phylogenetic tree optimized for blind people. The lowest point of the tree is the root, which symbolizes the universal common ancestor to all living beings. The tree branches out into three main groups: Bacteria (left branch, letters a to i), Archea (middle branch, letters j to p) and Eukaryota (right branch, letters q to z). Each letter corresponds to a group of organisms, listed below this description. These letters and the description should be converted to Braille font, and printed using a Braille printer. The figure can be 3D printed by copying the png file and using Cura or other software to generate the Gcode for 3D printing.
