This is our tree that started it all! 'A History of Existing Life' graphically represents all lineages of currently living organisms, positioned on the tree revealing how they are all related to one another and how old they are thought to be based on DNA studies and fossil evidence. There is a geological time line on the right side of the tree for easy reference.
The included 8 page booklet explains in more detail evolution and evolutionary trees. Also included are 24 game cards that can be used in conjunction with the History of Existing Life art print.
