I want to know the answer to the following question:
Why were political radicals such as Ernst Haekel so interested in On the Origin of Species?
All the background I'm provided with is that "Ernst Haeckel was particularly ardent, aiming to synthesise Darwin's ideas with those of Lamarck and Goethe while still reflecting the spirit of Naturphilosophie.". Is that enough to answer the question?
Answer: yes
