He attended University of Tübingen.
He completed a PhD in 1923.Beurlen was a proponent of orthogenesis and saltational evolution.
He used the term metakinesis (coined by Otto Jaekel) to describe sudden changes of development in organisms.
He also invented the term palingenesis as a mechanism for his orthogenetic theory of evolution.He was an assistant of Edwin Hennig.He was a proponent of National Socialist ideology and wrote about the Aryan race.He was director of the Zoologische Staatssammlung München, and as an ardent Nazi, refused to allow fossils to be moved during the war.
As a result, when the museum was hit on 24 April 1944, all of Ernst Stromer’s Cretaceous fossils from North Africa, including the Spinosaurus holotype, were destroyed
