Web17 Feb 2024 · Scientists have long used sea urchins as a model organism in developmental biology due to their easily visible embryos; furthermore, as many sea creatures (such as fish) also develop through embryonic and larval stages free in the water, any pollutant that harms sea urchin larvae may have consequences for other marine life too. Web1 Nov 2007 · Roux observed that if one cell is destroyed at the 2–cell stage, the remaining cell will develop to form a half–embryo. Roux theorized that development was mosaic; each cell was determined by the two-cell stage, as each cell division results in an unequal distribution of cellular material.
