1. In the late 19th century experimental embryology became established as a new
discipline. Explain the research goals of the experimental embryologists in
contrast to the Haeckel school. Describe the seminal experiments of Roux and
Driesch on early development of amphibians and sea urchins and explain how
they were interpreted.
2. Explain briefly Mendel's experiments and their implications for understanding
inheritance. What impact did the rediscovery of Mendel's experiments in 1900
have on evolutionary theory? Comment in your answer on why "Mendelism"
was initially thought to be in conflict with "Darwinism" and how this was
resolved later.
