WebAug 18, 2016 · Embryonic development proceeds through a series of differentiation events. The mosaic version of this process (binary cell divisions) can be analyzed by comparing early development of Ciona intestinalis and Caenorhabditis elegans.

Cell lineage can be determined by two methods, either through direct observation or through clonal analysis. During the early 19th century direct observation was used however it was highly limiting as only small transparent samples could be studied. With the invention of the confocal microscope this allowed larger more complicated organisms to be studied.
