The World of Hopfs

A small bedtime story about evolution

What is it?

The world of Hopf is a small story about the basic ingredients for evolution: Variation, Heritability and Selection. It is best read by kids together with their parents, but also by either of them alone. The making of the book was generously supported by the European Society for Evolutionary Biology ESEB.

Who made it?

The Hopfs were brought to life by Jan Heuschele, a biologist with a keen interest in evolution, scientific outreach and drawing. If you want to know more about his research and other projects feel free to visit his website or send him an email to jan[add]heuschele.com.
