From: High-precision morphology: bifocal 4D-microscopy enables the comparison of detailed cell lineages of two chordate species separated for more than 525 million years

Fig. 1

Cell lineage trees of the developments of a larvacean (left, Oikopleura dioica) and an ascidian (right, Phallusia mammillata) embryo. Different colors denote different tissue fates. Note the different time scales. Blue dotted line indicates respective timeline of stages depicted in Fig. 4. For the black lines, tissue fate was either not restricted to a single fate yet or a confident determination was not possible at the latest stage documented. Branches in the trees are arranged according to the same scheme (see first paragraph of “Results and Discussion” for details)
