Development mechanics
Development mechanics is a concept founded by Wilhelm His (1831–1904) and Wilhelm Roux (1850–1924) and continued by Hans Driesch (1867–1941) and Hans Spemann (1869–1941) and many others, which today is the beginning of a Developmental Physiology is considered. Developmental factors and mechanisms are now also the subject of developmental biology . It was z. Some of the researchers mentioned tried to influence the sequence of normal developmental stages by mechanical interventions in blastomeres and thus to prove the epigenetic character of fetal development. However, this concept offered the possibility, in addition to such experiments, to find other non-mechanical factors or “mechanisms” that have an influence on the normal development process. The validity of the preformation theory should be put to the test. The researchers thus established an experimental orientation in embryology , which is also known as causal development history. The connection to genetics later created u. a. Kristine Bonnevie (1872–1948) and Richard Goldschmidt (1878–1958).
