How many derived characteristics separate hag fish form chimps and what are they?

Hagfish and chimpanzees are separated by numerous derived characteristics, primarily due to their vast evolutionary divergence. Major differences include the presence of a backbone in chimps, complex brain structure, advanced social behaviors, and the development of opposable thumbs. In contrast, hagfish are jawless, have a simple body plan, and lack a vertebral column, relying on a notochord instead. These distinctions highlight the significant evolutionary adaptations that have occurred over millions of years.
