The reason is that something changed that caused them to be unsuccessful in their environment.
Sorry if it is not right.
The parent may have had an recessive gene that didn't show up in them but showed up in the the offspring!!
Given what we know, we can confirm that in summary, what makes a tunicate more complicated than a sea sponge is cellular differentiation.
<h3>What is cellular differentiation?</h3>
This is what we call the cells ability to specialize itself into a specific cell type. Some examples of this in humans include:
- Heart cells
- Digestive cells
- Reproductive cells
Due to this, tunicates have evolved different tissues, organs, and complete cell types, making them much more complicated organisms than sea sponges.
Therefore, we can confirm that due to the multiple tissues, organs, and systems developed through cellular differentiation, tunicates have become more complicated than sea sponges.

It is carried on the X chromosome.
Taking this test on Gradpoint, hope I helped.
