What is Bernhard Rensch?
'''Bernhard Rensch''' (21 January 1900 – 4 April 1990) was a [[Germany|German]] [[evolutionary biology|evolutionary biologist]], and [[ornithology|ornithologist]] who did field work in [[Indonesia]] and [[India]]. He is probably best known as one of the architects of the [[modern evolutionary synthesis]], which he popularised in Germany. His work on the evolution of geographically isolated populations, and on [[evolution]] above the [[species]] level, contributed to the modern synthesis. He also worked extensively on animal behavior ([[ethology]]). Rensch's education and scientific work was interrupted by service in the German military during both [[World War I]] and [[World War II]]. His [[autobiography]], published later in life, translates as 'Life of a biologist in a turbulent century'.<ref>Rensch B. 1979. ''Lebensweg eines Biologen in einem turbulenten Jahrenhundert''.
