The Continuity of Life Forms is a large mid-century modern mosaic and one of the earliest remaining works by local architect and artist Willard "Will" Martin, who also designed Pioneer Courthouse Square.

[1][2] In 1997, the zoo's entrance was relocated, and the mosaic became less visible, obstructed by a fence and out of the way for visitor access.

[1] In 2014, during construction of the zoo's conservation education center, the mosaic was removed and placed into storage.

[1][2] The funds allowed the Oregon Zoo Foundation to hire an art conservator and restoration artist to "ensure the accurate restoration and conservation of this splendid artwork for future generations".

"[1] The organization hopes the re-installation will introduce another generation to the artwork and Martin, who died in a plane crash in 1985.
