Phylogenetic Tree of Life Necklace

All life is connected, and this pendant represents the entirety of our Earth-bound biological extended family; diagram that shows the evolutionary relationship between species. Every form of life on earth comes from common ancestry, which you can see as the tiny vertical line in the center of the pendant. The little circle on the right side of the pendant shows where humans reside in the diagram. Although diagrams similar to phylogenetic trees had existed previously, Charles Darwin popularized the concept in The Origin of Species.
