Hans G. G. S. Haeckel
Hans G. G. S. Haeckel was a German biologist and philosopher known for his work in evolutionary theory and developmental biology. He contributed to understanding how living organisms develop and change over time, emphasizing that embryonic development mirrors evolutionary history—a concept called recapitulation. Haeckel also created detailed, artistic illustrations of microorganisms, which helped popularize evolutionary ideas. His work bridged science and philosophy, influencing how we view biological diversity and the connections among different species, while sparking ongoing discussions about the interpretation of evolutionary development.
