Ludwig Plate

Ludwig Hermann Plate (16 August 1862 – 16 November 1937) was a German zoologist and student of Ernst Haeckel. He wrote a "thorough and extensive defence" of Darwinism, but before Mendel's work had been assimilated in the modern synthesis.

Born in Bremen, Plate studied mathematics and natural sciences Bonn and in Jena, where he attended the lectures of Ernst Haeckel. In 1888, he achieved the 'Habilitation' in zoology at the University of Marburg. He was offered the Chair of Zoology at Jena University in 1909 through the help of Haeckel, and also became director of the Jena "Phyletisches Museum".

He coined the term Pleiotropy.

Evolutionary views

Plate was a proponent of what he called old-Darwinism or orthoevolution, which included a supposedly directed form of natural selection, orthoselection. According to Plate, old-Darwinism follows the ideas of Charles Darwin but also integrates other mechanisms of evolution.
