The correct answer is: B. are descended from a single ancestral species.

The hypothesis of the tree of life suggests that all living organisms share a common ancestor and that life has branched out over time, creating the diverse forms we see today. This concept implies a common lineage rather than a linear progression or static existence of species. If you have more questions or need further clarification, feel free to ask!
