Mainly because of high amount of details at all scales.<p>Here are some contemporary scientific infographics with Ernst Haeckel style applied: <a href="https://rybakov.com/blog/visualizing_complexity/" rel="nofollow">https://rybakov.com/blog/visualizing_complexity/</a>
There is a wonderful documentary about Ernst Haeckel's study of Radiolaria, which I highly recommend. The film is called Proteus: A 19th Century Vision (<a href="https://www.imdb.com/title/tt0391407/" rel="nofollow">https://www.imdb.com/title/tt0391407/</a>).
You can read all of "Kunstformen der Natur" (Artforms of Nature) at the Biodiversity Heritage Library, along with lots of other beautifully illustrated natural science literature.<p>Even though it's old, this is still useful scientific information, and digitizing it is very helpful to people without access to a 100-year-old zoological library. As you can see from selecting "Show OCR", there's still some work to be done to get the algorithms working on 19th century German blackletter fonts.<p><a href="https://www.biodiversitylibrary.org/item/182319#page/89/mode/1up" rel="nofollow">https://www.biodiversitylibrary.org/item/182319#page/89/mode...</a>
Haeckel's Art Forms of Nature are an astonishing achievement.<p>High resolution public domain images can be downloaded from the Library of Congress here: <a href="https://www.loc.gov/search/?fa=contributor:giltsch,+adolf" rel="nofollow">https://www.loc.gov/search/?fa=contributor:giltsch,+adolf</a><p>Unfortunately he was also a terrible racist. The Nazi party not only used his quotes – 'Politics is applied biology' – but also his justifications for the hierarchy of races, nationalism and social Darwinism.<p><a href="https://en.wikipedia.org/wiki/Ernst_Haeckel#Polygenism_and_racial_theory" rel="nofollow">https://en.wikipedia.org/wiki/Ernst_Haeckel#Polygenism_and_r...</a>
