Analyze the definition of an outgroup

An outgroup in a cladogram is a lineage that diverged prior to the common ancestor of the ingroup. It is evolutionary related to the ingroup, sharing a more distant common ancestor, rather than being "completely unrelated."

Evaluate the statement

The statement claims that the outgroup is "completely unrelated to the other groups." Because all life shares a common origin and the outgroup specifically shares a common ancestor with the ingroup, the statement is false.
