Biography
In 1928 - 1963 , professor of anatomy at the Free University of Brussels. [1] Corresponding member of the Royal Belgian Academy of Sciences in the zoology section since November 21, 1966 . [2] He participated in the embalming of the King of Belgium, Albert I. [3]
Evolutionary Views
Dalk saw in embryology a key to understanding evolution. To denote “sharp, deep, radical and at the same time viable transformations occurring in the cytoplasm of the egg as a morphogenetic system”, the term ontomization was proposed . According to Dalke, ontomations are caused by abrupt changes in external environmental factors, affecting simultaneously all females in the population during egg maturation. [4] This idea made it possible to overcome the difficulty that Goldschmidt's theory of macromutations faced, since it removed the question of finding a sexual partner by mutant individuals. [five]
