Jan 1, 2012 · He thought that separating cells, rather than killing one cell as Roux had done, would lead to a more decisive confirmation of Roux's conclusions. Driesch began his experiment by placing approximately one hundred two-celled sea urchin embryos and a small amount of sea water into a small glass container.
Though Roux’s findings were quickly challenged by an 1892 experiment conducted by Hans Driesch and again in 1910 by Jesse Francis McClendon, Roux maintained that an organism’s cells underwent predetermined as opposed to epigenetic development, meaning the path of formation the cells took was already present from the outset.

Wilhelm Roux perform this "ablation" experiment to test Weismann's therory of "determinants" and mosaic development. The results of ablating one cell of the two cell embryo was a half embryo. This was consistent with Weismann's prediction of localized determinants and mosaic development.

Apr 4, 2024 · Wilhelm Roux (born June 9, 1850, Jena, Saxony [Germany]—died Sept. 15, 1924, Halle, Ger.) was a German zoologist whose attempts to discover how organs and tissues are assigned their structural form and functions at the time of fertilization made him a founder of experimental embryology. A student of German biologist Ernst Haeckel, Roux ...

One of the first scientists to test Weismann's hypothesis was Wilhelm Roux, a young German embryologist. In 1888, Roux published the results of a series of defect experiments in which he took 2- and 4-cell frog embryos and destroyed some of the cells of each embryo with a hot needle.
Abstract. This last essay in the series commemorating Wilhelm Roux (1850–1924) is devoted to speculative developmental theories (or models as they would be called today) proposed in the decade following Roux’s manifesto on Entwickelungsmechanik (see Sander 1991a). That decade, 1885–1895, not only saw Roux’s pioneering experimental ...
