Why Is James Cossar Ewart Influential?

(Suggest an Edit or Addition)

According to Wikipedia, James Cossar Ewart FRS FRSE was a Scottish zoologist. He performed breeding experiments with horses and zebras which disproved earlier theories of heredity. Life Ewart was born in Penicuik, Midlothian, Scotland, the son of Jean Cossar and John Ewart, a joiner. He studied medicine from 1871 to 1874 at the University of Edinburgh where he graduated with an MB ChB. After graduation, he became an anatomy demonstrator under William Turner and then held the position of Curator of the Zoological Museum at University College, London, where he assisted Ray Lankester by making zoological preparations for the museum and providing teaching support for Lankester's course in practical zoology. In 1878 he returned to Scotland to take a post of Regius Professor of Natural History at the University of Aberdeen from where he moved to the University of Edinburgh in 1882, staying in the post until 1927. In Aberdeen he encountered James Duncan Matthews, a mature student and they became friends until Matthew's premature death in 1890.
