Answer:
The hypothesis that states that viruses originated from more complex cells is called the regressive hypothesis.
Explanation:
The regressive hypothesis -also called <u>degenerative hypothesis</u>- raises the possibility that viruses originally were cells that behaved as symbionts or parasites of other cells, and this condition of dependence could have originated the disappearance of genes, becoming structures formed by nucleic acid inside a viral capsid (virus).
Some evidence gathered to support this theory suggests that some bacteria, such as rickettsia, need to parasitize a cell in order to replicate, just as viruses do.
