Description
This wax model is part of a series of 25, created by Adolf Ziegler to show the development stages of the amphioxus (or lancelet, a fish-like chordate). The series is based on zoologist Berthold Hatschek’s research on amphioxi, which contributed to the understanding of the evolution of vertebrates and the development of comparative embryology.

The field of embryology expanded in Germany in the mid- to late 19th Century. However, because it was difficult to obtain embryos for study or the embryos were too delicate to be preserved, embryologists struggled to study their developmental stages. In response, Adolf Ziegler began making wax models as research and teaching aids.

Ziegler became known for his excellent models and in 1867, he left his role at the University of Freiberg to open a model-making studio, later working with his son Friedrich. Ziegler collaborated with several embryologists, effectively publishing their research in model form. As well as being used for research and in teaching, the models were the first depictions of embryos for public display. Many were exhibited and won medals at world fairs.
